[New Class] The Tactician, aka the mundane caster

[yisopo]

NOTES

What if a martial classe could wield the versatility of spellcasters? Enter the Tactician.

They possess a diverse array of gambits, each akin to a level-1 spell in complexity (at least that's what I would like). But how do they stay competitive as levels progress? Simple: they blend multiple gambits in a single turn, maintaining pace with other classes as they weave intricate combinations of tactics on the battlefield.

Essentially, from a mechanical standpoint, it's as if a spellcaster had magic building blocks and by combining them could create progressively more potent spells. However, thematically, the Tactician's gambits are purely mundane. No type of magic, hence no: teleportation, summoning, flight, and the like.

Spoiler: Spell Points adaptation

Show

As you can see, the progression of the Tactic Points has been directly taken from the "Spell Points" variant. The only difference (purely formal, while substantively unchanged) is that, in order to simplify the gambit system (where a gambit should correspond to a 1st-level spell), a gambit has a value of 1 instead of 2. So all the points have been halved.

This is my first draft, so it's still highly subject to change. In fact, I've posted it here specifically to gather as much feedback as possible and improve it. Please let me know if there's anything to adjust for balance or general improvements.


THE TACTICIAN

In a world where battles are fought with steel and magic, the Tactician embodies the essence of strategy and cunning. They emerge as the mastermind behind every move, orchestrating the flow of combat with precision and foresight. Armed not only with weapons but also with intellect, the Tactician navigates the battlefield like a chess grandmaster, always several steps ahead of their foes.

They are the architects of victory, turning the chaos of battle into a symphony of calculated strikes and gambits.

EQUIPMENT
You start with the following equipment, in addition to the equipment granted by your background:
• (a) scale mail or (b) leather armor, longbow, and 20 arrows
• (a) a martial weapon and a shield or (b) two martial weapons
• (a) a light crossbow and 20 bolts or (b) two hand axes
• (a) a dungeoneer's pack or (b) an explorer's pack

TACTICAL COMBAT
Beginning at 1st level, your mental acuity allows you to utilize various tactics during combat. Your calculating genius is represented by a pool of Tactical Points.

TACTICAL POINTS
The Tactician table shows how many tactical points you have to use your tactical abilities, called “gambits”. To use these gambits, you must expend those points: 1 tactical point for each gamble.

You can combine gambits together in the same turn with these constrains:
1. The column “Max Tactical Points per Turn” show how many tactical points you can use in singe turn of yours.
2. A gambit can force a Saving Throw to a specific enemy only once per round.
3. A specific water gambit can only be used once per round.
4. Only one gambit requiring a reaction is possible to use in a round (exception: “God of the Battlefield” feature).

In general gambits don’t expend actions or bonus actions; but some gambits can use a reaction.

You regain all expended tactical points when you finish a long rest.

GAMBITS KNOWN
The “Gambits Known” column of the Tactician table shows how many gambles you know at each level.

Additionally, when you gain a level in this class, you can choose one of the gambits you know and replace it with another gambit.

Some of the gambits require your target to make a saving throw to resist the gambit’s effects. The saving throw DC is calculated as follows:

Gambit save DC = 8 + your proficiency bonus + your Intelligence modifier

ANALYTICAL FIGHT
At 1st level, when you attack with a weapon, you can use your Intelligence modifier, instead of Strength or Dexterity, for the attack and damage rolls.

Your analytical mind is so focused that if you use this feature, you can’t cast spells or concentrate on them for 1 minute.

MENTAL RECOVERY
Starting at 2nd level, once per long rest when you finish a short rest, you can choose to recover an amount of tactical points as shown in the Tactical table.

WARFARE PHILOSOPHY
At 3rd level, you choose a warfare philosophy that shape the way you see your enemies and the battlefield. Your choice grants you features at 3rd level and again at 6th, 10th, and 14th level.

ABILITY SCORE IMPROVEMENT
When you reach 4th level, and again at 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

WEAKNESS ASSESSMENT
At 5th level, if you don’t spend any tactical points in your turn, you add 1d10 to the attack's damage roll. You cannot use this feature as a reaction or with the "Extra Attack" feature.

The feature improves at higher levels. This damage increases by 1d10 when you reach 11th level (2d10), and 17th level (3d10).

MASTER OF THE BATTLEFIELD
At 18th level, you have achieved great mastery over the battlefield. You may use a gambit belonging to your Warfare Philosophy even if you don’t know it.

You can use this feature once per round.

GOD OF THE BATTLEFIELD
When you reach 20th level, your ability over the battlefield becomes unparalleled. Your speed is increased by 10 feet and you have +3 to your AC against opportunity attacks.

In addition, when you use a reaction, you can combine two gambits requiring a reaction in the same round.


WARFARE PHILOSOPHY
While many adventurers excel in combat prowess, tacticians immerse themselves in the complexities of warfare, aspiring to dominate the battlefield much like a skilled chess player commands the board.

Through their rigorous studies, they develop unique ideologies regarding combat, known as Warfare Philosophies. Among these, two stand out: The Fire Philosophy and the Water Philosophy.

WARFARE PHILOSOPHY: FIRE

The Fire Tactician epitomizes the art of direct warfare, honing their skills to deliver devastating blows with unparalleled accuracy. They favor straightforward tactics that prioritize dealing maximum damage to their foes. Armed with keen insight and unwavering determination, they strike fear into the hearts of their enemies with every calculated assault.

TACTICAL ATTACK
Starting at 3rd level, when you didn’t hit with an attack roll against a creature, you can reroll and keep the result of the second roll.

You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

BLAZING BODY
At 6th level, you gain proficiency in Constitution saving throws. If you already have this proficiency, you instead gain proficiency in Dexterity or Charisma saving throws (your choice).

In addition, you have resistance to bludgeoning.

ENEMY ASSESSMENT
At 10th level, you add +2 to each attacks and damaging gambits.

FIRE SAVANT
At 14th level, when you use a fire gambit you can use it without spending tactical points.
You can use this feature a number of times equal to your proficiency bonus.

WARFARE PHILOSOPHY: WATER

The Water Tactician embodies the principles of indirect warfare, utilizing cunning strategies and astute defenses to outmaneuver adversaries with finesse. They manipulate the battlefield like a masterful tactician, employing devious tactics and shrewd defenses to secure triumph.

TACTICAL DEFENSE
Starting at 3rd level, when a creature makes an attack roll and hit you, you can force it to reroll. It keeps the result of second roll.

You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

FLOWING SOUL
At 6th level, Your Gambit save DC increases by 1.

BATTLEFIELD ASSESSMENT
At 10th level, you have a bonus to your initiative rolls equal to +5.

WATER SAVANT
At 14th level, when you use a water gambit you can use it without spending tactical points.
You can use this feature a number of times equal to your proficiency bonus.

IMPROVED CLIMB
Trigger: On your turn
You gain the ability to move up, down, and across vertical surfaces and upside down along ceilings. Your climbing speed is equal to your walking speed.
If you use both hands for climbing, this gambit lasts 1 minute. If you use only hand for climbing, leaving the other one free to hold an object (a weapon, a shield, …), this gambit lasts 2 rounds.

IMPROVED JUMP
Trigger: On your turn
For 1 minute, your jumps are improved. With a running start your long jump is 60 feet horizontally and your high jump is 20 feet off the ground. Without a running start your long jump is 45 feet horizontally and your high jump is 15 feet off the ground.
If there are obstacles in the way you cannot jump over any obstacles that are taller than 10 feet.

IMPROVED SENSES
Trigger: On your turn
You can automatically sense any invisible or hiding creatures within 60 feet that don't have total cover from you. Until the start of your next turn, you know their positions so you suffer no penalties when targeting those creatures with attacks, and they gain no benefits targeting you.

Trigger: On your turn
For 2 turns, your speed is doubled and you have +2 to your AC against opportunity attacks.

INTIMIDATING PRESENCE

You can use your reaction and attempt to grapple the creature. If you succeed, you can throw the creature up to 40 feet away from you and it is prone.

SLOW FALL
Trigger: You are falling (reaction)
You use your reaction to exploit the shape of your clothes and you choose the right movement of your body, so your rate of descent slows, and you prepare for the impact. You take one-third of the falling damage.

STEALTHY SHOT
Trigger: You make a ranged weapon attack while hidden
You can attempt to remain unseen. The attack does not automatically reveal your position. Make a Dexterity (Stealth) check. If the result of this check beats the passive Wisdom (Perception) score of each enemy that could potentially observe you, you stay hidden. If the attack hits, add 1d10 to the damage roll.

WILLPOWER FORTITUDE
Trigger: You fail a saving throw (reaction)

[JNAProductions]

Chassis
As written, they don't get light armor. I'm assuming that was unintentional omission?
Maybe give them a third skill prof.
Equipment includes chain mail that they do not have proficiency in.

Tactical Combat
When you say max in a turn, do you mean turn, or round? Just want to be sure.

Analytical Fight
I would probably remove the "Can't cast" restriction, but keep the "Can't Concentrate" one. Or lift the "Can't cast" at some level.

Mental Recovery
Once per long rest, not day.

Weakness Assessment
How does this interact with off-turn attacks?
How does this interact with extra attacks, either form multiclassing or TWF?

Straight
First off, the name feels kinda weird. Maybe Orthodox instead?
Tactical Attack is a big ol' pile of "Eh. Not that good."
Savant also feels pretty lame.
Assessment adds +2 or +4 with 2d6 weapons?
Overall, this subclass feels dull.

Curved
Defense feels a bit better than attack, but still underwhelming.
Savant, same deal.
Battlefield Assessment, why is the bonus so damn big? Maybe add +Prof to it, so at least it'll scale to that later.

Gambits, Straight
Rapid Attack is the first one that sticks out to me. Depending on how it interacts with magic weapons, this could be pretty nutso-a 20th level Tactician could, in theory, make 10 attacks in one turn. One normal, one from TWF, and eight from Rapid.

Gambits, Gay
Bait and Switch combined with Avoid could, as written, combo to be 1d10+5 to your AC provided you're adjacent to anyone. You get +1d10 AC regardless of if you switch, so... Yeah. That's kinda nuts.
Commander's Plan feels weird, since Bonus Actions usually rely on main actions.
Shocking Strike is insane, due to free crits.

Overall Notes
Some fiddly bonuses that feel out of place.
Might be weak in actual play.
And it suffers from the issue of its best options are available from level one-so as you get more Gambits, you're picking whatever you wanted less than the priority, since you already have those.

[yisopo]

Hi JNAProductions, first of all, thank you very much for the feedback. This is my first time creating a homebrew class. Every observation of yours is highly valuable. (Plus, English is not my first language.)

Chassis
As written, they don't get light armor. I'm assuming that was unintentional omission?

Yes, I will correct it.

Chassis
Maybe give them a third skill prof.

I was undecided about this, but I will follow your advice.

Chassis
Equipment includes chain mail that they do not have proficiency in.

I will fix it.

ChassisTactical Combat
When you say max in a turn, do you mean turn, or round? Just want to be sure.

Turn.

Analytical Fight
I would probably remove the "Can't cast" restriction, but keep the "Can't Concentrate" one. Or lift the "Can't cast" at some level.

I fear it might be too strong for multiclassing with the Wizard. Don't you think?

Mental Recovery
Once per long rest, not day.

I will fix it.

Weakness Assessment
How does this interact with off-turn attacks?
How does this interact with extra attacks, either form multiclassing or TWF?

I design this feature as a mundane version of cantrips: something to do when you don't have tactical points or don't want to use them for same reason.

I think this feature is OK with TWF. But I didn't think about the interaction with extra attack from multiclassing. I will fix it adding "You cannot use this feature as a reaction or with the 'Extra Attack' feature."

Straight
First off, the name feels kinda weird. Maybe Orthodox instead?

I was thinking to change the names in: Fire and Water. Fire = more damages, direct. Water = more flexible/control, indirect.

Tactical Attack is a big ol' pile of "Eh. Not that good."
Savant also feels pretty lame.
Assessment adds +2 or +4 with 2d6 weapons?
Overall, this subclass feels dull.

While I was designing the subclasses, I thought that the class was so strong/solid that it required subclasses that weren't too strong. But perhaps I've depowered it too much?

Regarding the dullness, I think the class with so many options is the perfect opposite of it. So I didn't want to include even more options in the subclasses. But I will think about that.

"Assessment adds +2 or +4 with 2d6 weapons?" --> I'm thinking to change it from "you add +2 to each weapon damage die" to "you add +2 to each attacks and damaging gambits". What do you think?

I will try to design it a more solid and interesting subclass. Here too, if you have any suggestions, they are more than welcome.

Curved
Defense feels a bit better than attack, but still underwhelming.
Savant, same deal.
Battlefield Assessment, why is the bonus so damn big? Maybe add +Prof to it, so at least it'll scale to that later.

I want "Battlefield Assessment" to be on par with "Enemy Assessment".

Gambits, Straight
Rapid Attack is the first one that sticks out to me. Depending on how it interacts with magic weapons, this could be pretty nutso-a 20th level Tactician could, in theory, make 10 attacks in one turn. One normal, one from TWF, and eight from Rapid.

2d6 (greatsword) + 5 (Intelligence modifier) + 2 (Enemy Assessment) + 8d10 (damaging gambits) + 16 (Enemy Assessment x 8) = 2d6 + 8d10 + 23 = 75 damages average. This combination should be comparable to a level-9 spells. So I think this is acceptable, right?
Whereas, regarding the magic weapons, do you have some examples?

One clarification: "Rapid Attack" is just for attacking a different creature from the previous one(s). Otherwise you can (and should) combo other damaging gambits.

Gambits, Gay
Bait and Switch combined with Avoid could, as written, combo to be 1d10+5 to your AC provided you're adjacent to anyone. You get +1d10 AC regardless of if you switch, so... Yeah. That's kinda nuts.

I will change with a +2 AC bonus. (Avoid works only against one creature.)

Commander's Plan feels weird, since Bonus Actions usually rely on main actions.

I will ponder on this one.

Shocking Strike is insane, due to free crits.

I took "Hold Person", a 2nd-level spell, and depowered it: Con saving throw instead of Wistom; 1 round duration instead of potentially multiple rounds. However, I didn't realized I powered it too removing the "humanoid" constrain. I'm thinking to change "paralysed" with "stunned".

Overall Notes
Some fiddly bonuses that feel out of place.
Might be weak in actual play.

Ironically, I was holding back because I thought it was too strong. :-D I will fix it!

And it suffers from the issue of its best options are available from level one-so as you get more Gambits, you're picking whatever you wanted less than the priority, since you already have those.

My ideal plan is to have all gambits (more or so) equally good. So, the real benefit of progressing with this class is to have more gambits for flexibility and, above all, more tactical points for more combos. The problem with tier gambits, you narrow the available options: if you are level-20 why would you want to use tier-1 gambits?

Anyway, mechanically what do you think about the general concept of a class that compose various gambits in order to form a "complete maneuvers"? And thematically, about a mundane class with a great variety like casters?

[JNAProductions]

I'm not sure you've met your goals. Especially since it's almost purely combat-there's a few skill boosters, lifted from Maneuvers, but that's about it. And I feel that there's a good chance you'll end up spamming the same gambits every turn just by finding one that works well with your parry.
Commander's Strike on a Rogue, for instance.

[yisopo]

Changelog 1:

• Proficency in Light armor added
• Scale mail instead of chain mail
• Three skills instead of two
• Mental Recovery: "per long rest" instead of "per day"
• Weakness Assessment: "You cannot use this feature as a reaction or with the 'Extra Attack' feature" added
• Subclasses names: Fire and Water instead of Straight and Curved
• Enemy Assessment: "you add +2 to each attacks and damaging gambits" instead of "you add +2 to each weapon damage die"
• Bait and Switch: "+2 to AC" instead to "+1d10 to AC"
• Shocking Strike: stunned instead of paralyzed

[yisopo]

I'm not sure you've met your goals. Especially since it's almost purely combat-there's a few skill boosters, lifted from Maneuvers, but that's about it.

This is a mundane class so it is OK for me not to have fly, invisibility, mind control, summoning and the like. But I want to have many combat options anyway.

And I feel that there's a good chance you'll end up spamming the same gambits every turn just by finding one that works well with your parry.
Commander's Strike on a Rogue, for instance.

I am well aware that this version is just a very improvable draft. But do you really think that, in general, my project isn't feasible with this core? I need your and other's advices. :-)

Regarding "Commander's Strike" I can fix it or even remove it entirely if needed.

If you were a level-5 Tactician, which 8 gambits would you choose?

Moreover, as a spellcaster doesn't always want to cast their highest spell, the Tactician doesn't always want to use the maximum gambits each turn. And so probably, different number of gambits = different choices of gambits.

[yisopo]

Changelog 2:

• Tactical Attack: "when you didn’t hit with an attack roll against a creature, you can reroll and keep the result of the second roll." instead of "when you are about to make an attack roll against a creature, you can have advantage to the roll."
• Blazing Body feature added at 6th level for Fire.
• Fire Savant at level 6 removed; it stays at level 14.
• Flowing Strike feature added at 6th level for Fire.
• Water Savant at level 6 removed; it stays at level 14.
• Battlefield Assessment: "+5 initiative bonus" instead of "+6".

Some changes are inspired by JNAProductions's advices of making the subclasses more interesting.

What do you think? Is Flowing Strike feature too strong? I copied from the Eldritch Knight but here is much stronger because the way the Tactician works.
