Eidolon Blade [PrC]

[The Demented One]

Eidolon Blade

Eidolon Blades are master Soulknives who have unlocked the secret of eidolons. They have learned to transform their mind blades into channels for their own subconscious–eidolons. By opening the mind blade as a psychic conduit, they can bestow it with sentience, a persona derived from their own subconscious, along with considerable power. Even master swordsmen are wary of crossing steel with an Eidolon Blade, for he never fights without an ally or a weapon–he has both in his eidolon.

Class Features
All the following are class features of the Eidolon Blade prestige class.

Weapon and Armor Proficiency
You gain no additional weapon or armor proficiencies.

Awaken Least Eidolon (Su)
At 1st level, your mind blade becomes an eidolon. It is treated as an intelligent object. Its alignment is decided by the DM, although it is always within one step of yours. It has two mental ability scores of 12 and one of 10. These scores are decided by you and, once determined, cannot be changed. It can communicate with you through empathy alone, and has 30 ft. vision and a sense of hearing. It has no powers, lesser or greater, and no dedicated purpose. When your mind blade is unformed, it can still communicate with you–and only you–as a voice in your head, though it cannot perceive the outside world. If you split your mind blade, then both are intelligent, though each of their mental scores is 2 less than normal.

Mind Blade Enhancement (Su)
Eidolon Blade levels stack with Soulknife levels to determine the enhancement bonus of your mind blade, but not for purposes of psychic strike damage, mind blade special abilities, or any other Soulknife class features.

Lesser Eidolon Power (Ps or Su)
At 2nd, 4th, and 6th levels, your mind blade gains a minor power. Rather than using the standard list of minor powers, choose powers from the list of below. Your mind blade cannot use its powers, minor or greater, while it is unformed or split into multiple blades. Powers limited to a certain number of uses per day can only be used that many times a day, regardless of how many times you form or dissipate the blade. Your mind blade’s manifester level is equal to your class level, and all psi-like abilities are fully augmented for its manifester level. The minor powers you may choose from are as follows:

{table=head]Power|Description
Concealing Amorpha|Mind blade can use concealing amorpha on you 1/day.
Detect Hostile Intent|Mind blade can use detect hostile intent 3/day.
Detect Psionics|Mind blade can use detect psionics at will.
Dispel Psionics|Mind blade can use dispel psionics 1 /day.
Eradicate Invisibility|Mind blade can use eradicate invisibility 1/day.
Know Direction|Mind blade can use know direction and location at will.
Precognition|Mind blade can use either defensive precognition or offensive precognition on you a total of 3/day.
Prevenom|Mind blade can use prevenom weapon on itself 3/day.
Psicraft|Mind blade has 10 ranks in Psicraft
Vigor|Mind blade can use vigor on you 3/day.
[/table]

Shape Eidolon (Su)
With sentience comes greater control over form. At 2nd level, you may shape your mind blade as a standard, rather than a full-round, action. In addition, you can change your mind blade into the form of any one-handed or light martial or simple weapon, or any one-handed exotic weapon you are proficient with. If you change it into a light weapon, you may split it as usual.

Aligned Eidolon (Su)
At 3rd level, your mind blade becomes aligned, and is treated as a weapon of one aspect of its alignment, chosen by you, for overcoming damage reduction. If the mind blade’s alignment is different than your own, then you must choose the aspect of its alignment it shares with you. If either you or your mind blade is true neutral, or your mind blade has no non-neutral aspect of alignment in common with you, then you may align the blade with the alignment of your choice. Thus, the chaotic neutral mindblade of a chaotic good Eidolon Blade would be chaotically aligned, while the neutral evil mind blade of a true neutral Eidolon Blade could be aligned with any alignment of his choice.

Awaken Lesser Eidolon (Su)
At 3rd level, your mind blade’s two ability scores of 12 increase to 14, though its ability score of 10 remains unchanged. It gains the power of speech, and the range of its vision increases to 120 ft.

Eidolon Focus (Su)
At 5th level, you may store your psionic focus in your mind blade. You can spend a full-round action attempting to psionically focus your mind blade. At any time when you need to expend your psionic focus, you can expend your mind blade’s psionic focus instead. The mind blade cannot focus itself. If your mind blade dissipates, the stored focus is lost.

Awaken Greater Eidolon (Su)
At 6th level, your mind blade’s two ability scores of 14 increase to 16, though its ability score of 10 remains unchanged. It gains the ability to read any languages it can speak, and it gains darkvision out to 60 ft.

Adamant Eidolon (Su)
At 7th level, your mind blade is treated as an adamantine weapon for ignoring object’s hardness and for overcoming damage reduction.

Greater Eidolon Power (Ps or Su)
At 8th and 10th levels, your mind blade gains a greater power. Rather than using the standard list of greater powers, choose powers from the list of below. Greater powers function exactly like minor powers do.

{table=head]Power|Description
Adapt Body|Mind blade can use adapt body on you 1/day.
Aura Sight|Mind blade can use aura sight at will.
Correspond|Mind blade can use correspond 3/day.
Energy Blade|Mind blade can use weapon of energy on itself 1/day.
Keen Edge|Mind blade can use psionic keen edge on itself 3/day.
Psychic Strike|Mind blade’s psychic strike damage increases by 1d8.
Second Chance|Mind blade can use second chance on you 1/day.
Truevenom|Mind blade can use truevenom weapon on itself 1/day.
True Seeing|Mind blade can use psionic true seeing 1/day.
Vampiric Blade|Mind blade can use vampiric blade on itself 3/day.
[/table]

Awaken Major Eidolon (Su)
At 9th level, your mind blade’s two ability scores of 16 increase to 18, though its ability score of 10 remains unchanged. It gains the ability to communicate telepathically and to read magic, and the range of its darkvision increases to 120 ft. It gains blindsense out to 30 ft.

Eidolon Unbound (Su)
At 10th level, your mind blade gains the ability to move and attack foes of its own volition. As a swift action, you may release a held mind blade to act on its own. You cannot use this ability if your mind blade is split. The released mind blade functions as if it were a magic weapon with the dancing special ability. However, instead of fighting for four rounds after being released, instead, each round the mind blade is released, excluding the round you released it, you must make a Concentration check. The DC of the check is 20, plus 5 for each previous round the mind blade has been released. If you fail the check, the mind blade dissipates and reforms in your hand. Otherwise, it continues fighting on.

Intelligent weapons for soulknives? I like. You might want to lower the BAB requirements since soulknives have only cleric BAB progression.

[Were-Sandwich]

Mesa like.

[Khantalas]

I was hoping for some cool Ghostwalk action. You crushed my dreams, TD1.

[martyboy74]

Can the blade use its eidolon powers while it is unbound?

[Raum]

I like the class as a whole. I do have a few questions or comments on specific powers though.

Awaken Least Eidolon (Su)
At 1st level, your mind blade becomes an eidolon. It is treated as an intelligent object. Its alignment is decided by the DM, although it is always within one step of yours. It has two mental ability scores of 12 and one of 10. These scores are decided by you and, once determined, cannot be changed.

If you split your mind blade, then both are intelligent, though each of their mental scores is 2 less than normal.

Looks cool. I like the idea of summoning idealized images of blades as mind blades, it seems appropriate somehow. :)

Mind Blade Enhancement (Su)
Eidolon Blade levels stack with Soulknife levels to determine the enhancement bonus of your mind blade, but not for purposes of psychic strike damage, mind blade special abilities, or any other Soulknife class features.

You may want to simply create a progression specific to Eidolon Blades and state that it stacks with enhancements from other classes. Not a big deal. just seems easier than specifying all the purposes for which levels don't stack.

Lesser Eidolon Power (Ps or Su)
At 2nd, 4th, and 6th levels, your mind blade gains a minor power. Rather than using the standard list of minor powers, choose powers from the list of below. Your mind blade cannot use its powers, minor or greater, while it is unformed or split into multiple blades. Powers limited to a certain number of uses per day can only be used that many times a day, regardless of how many times you form or dissipate the blade. Your mind blade’s manifester level is equal to your class level, and all psi-like abilities are fully augmented for its manifester level. The minor powers you may choose from are as follows:

{table=head]Power|Description
Concealing Amorpha|Mind blade can use concealing amorpha on you 1/day.
Detect Hostile Intent|Mind blade can use detect hostile intent 3/day.
Detect Psionics|Mind blade can use detect psionics at will.
Dispel Psionics|Mind blade can use dispel psionics 1 /day.
Eradicate Invisibility|Mind blade can use eradicate invisibility 1/day.
Know Direction|Mind blade can use know direction and location at will.
Precognition|Mind blade can use either defensive precognition or offensive precognition on you a total of 3/day.
Prevenom|Mind blade can use prevenom weapon on itself 3/day.
Psicraft|Mind blade has 10 ranks in Psicraft
Vigor|Mind blade can use vigor on you 3/day.
[/table]

On the minor powers, you may want to assign a set number of power points. Primarily for augmentation purposes...else a 3rd level EB with the Dispel Psionics power can't manifest at all...can't use 5 points yet. Alternatively, base manifester level on all manifesting classes rather than on the EB class.

Shape Eidolon (Su)
With sentience comes greater control over form. At 2nd level, you may shape your mind blade as a standard, rather than a full-round, action. In addition, you can change your mind blade into the form of any one-handed or light martial or simple weapon, or any one-handed exotic weapon you are proficient with. If you change it into a light weapon, you may split it as usual.

Why not two handed swords also? The soulknife can already shape it into a bastard sword and use it two handed.

Aligned Eidolon (Su)
At 3rd level, your mind blade becomes aligned, and is treated as a weapon of one aspect of its alignment, chosen by you, for overcoming damage reduction. If the mind blade’s alignment is different than your own, then you must choose the aspect of its alignment it shares with you. If either you or your mind blade is true neutral, or your mind blade has no non-neutral aspect of alignment in common with you, then you may align the blade with the alignment of your choice. Thus, the chaotic neutral mindblade of a chaotic good Eidolon Blade would be chaotically aligned, while the neutral evil mind blade of a true neutral Eidolon Blade could be aligned with any alignment of his choice.

Hmm, I don't like the idea of an evil weapon being capable of aligning with good. How about adding a statement limiting aligning to alignments that do not oppose the alignment of either blade or wielder?

Awaken Lesser Eidolon (Su)
At 3rd level, your mind blade’s two ability scores of 12 increase to 14, though its ability score of 10 remains unchanged. It gains the power of speech, and the range of its vision increases to 120 ft.

Have you considered allowing the blade to see out of it's wielder's eyes when unmanifested at some level?

Eidolon Focus (Su)
At 5th level, you may store your psionic focus in your mind blade. You can spend a full-round action attempting to psionically focus your mind blade. At any time when you need to expend your psionic focus, you can expend your mind blade’s psionic focus instead. The mind blade cannot focus itself. If your mind blade dissipates, the stored focus is lost.

Cool, I like it.

Awaken Greater Eidolon (Su)
At 6th level, your mind blade’s two ability scores of 14 increase to 16, though its ability score of 10 remains unchanged. It gains the ability to read any languages it can speak, and it gains darkvision out to 60 ft.

Speaking of known languages, do you specify which languages the blade knows? Or how it learns more? I may have simply missed it if you did...

Adamant Eidolon (Su)
At 7th level, your mind blade is treated as an adamantine weapon for ignoring object’s hardness and for overcoming damage reduction.

Nice.

Greater Eidolon Power (Ps or Su)
At 8th and 10th levels, your mind blade gains a greater power. Rather than using the standard list of greater powers, choose powers from the list of below. Greater powers function exactly like minor powers do.

{table=head]Power|Description
Adapt Body|Mind blade can use adapt body on you 1/day.
Aura Sight|Mind blade can use aura sight at will.
Correspond|Mind blade can use correspond 3/day.
Energy Blade|Mind blade can use weapon of energy on itself 1/day.
Keen Edge|Mind blade can use psionic keen edge on itself 3/day.
Psychic Strike|Mind blade’s psychic strike damage increases by 1d8.
Second Chance|Mind blade can use second chance on you 1/day.
Truevenom|Mind blade can use truevenom weapon on itself 1/day.
True Seeing|Mind blade can use psionic true seeing 1/day.
Vampiric Blade|Mind blade can use vampiric blade on itself 3/day.
[/table]

Same comments made with minor powers apply here.

Awaken Major Eidolon (Su)
At 9th level, your mind blade’s two ability scores of 16 increase to 18, though its ability score of 10 remains unchanged. It gains the ability to communicate telepathically and to read magic, and the range of its darkvision increases to 120 ft. It gains blindsense out to 30 ft.

Blindsense to 30' is a bit powerful, how powerful depends on whether it negates the 50% miss chance or not. As written, I'd say it doesn't simply because the blade has to tell it's wielder where the enemy is. If it is meant to negate the miss chance, I'd say it may be too powerful.

Eidolon Unbound (Su)
At 10th level, your mind blade gains the ability to move and attack foes of its own volition. As a swift action, you may release a held mind blade to act on its own. You cannot use this ability if your mind blade is split. The released mind blade functions as if it were a magic weapon with the dancing special ability. However, instead of fighting for four rounds after being released, instead, each round the mind blade is released, excluding the round you released it, you must make a Concentration check. The DC of the check is 20, plus 5 for each previous round the mind blade has been released. If you fail the check, the mind blade dissipates and reforms in your hand. Otherwise, it continues fighting on.

Have you considered rephrasing this to make it similar to a caster concentrating on a spell (requires a standard action)? Not sure which method I prefer to tell the truth, but needing to hit a DC increasing by 5 each round may be a bit underpowered for a capstone ability.

As I said, I like what you've done overall!
