Aside from the Archivist and Spell-to-power Erudite who can use spells like Divine Power and Haste?

Aside from the Archivist and Spell-to-power Erudite who can use spells like Divine Power and Haste?

Any arcane caster with level 4 spells and Arcane Disciple[War,Pride,Celestia,Competition,or Orc] or anyone with a sufficient level of Use Magic Device.

[Vaz]

Any psionic character can pick up Divine Power (or any Arcane or Divine spell) thanks to the StP Erudite wording, provided that they can take Expanded Knowledge for 4th level spells (or appropriate) , and the Ardent in particuoar can pick it up through the same wording, and use the Substitute Power ACF to add it to the respective mantle (Conflict, Guardian, Mental Might, Physical Power being the most likely).

Haste is appropriate for the Time Mantle, and some others.

Linked Power with Dominant Mantle cuts your action economy in half to buff up making it more worthwile to manifest buff powers in this way.

I also think you are underselling Persistent Spell.

Persistent Spell is normally a waste. It takes a spell of 3rd level, and makes it last all day at the cost of a 9th level spell, or a 1st level for a 7th etc, which is wasteful. The mitigation of this additonal cost means you have higher level spells permanancied, and/or have any lower level spell take less of a spell slot to cast.

Obviously, there is the benefit of a spell that otherwisr lasts for 3 minutes (typically the more powerful buff spells) actually last all day, but being able to throw down a dozen 24 hour spells, even at +2 cost means you're much more powerful until a dedicated dispeller comes along (which is why you are also an Item Crafter and make 50 spellblade shuriken) than many others in the game.

[Eldariel]

Any arcane caster with level 4 spells and Arcane Disciple[War,Pride,Celestia,Competition,or Orc] or anyone with a sufficient level of Use Magic Device.

Also Clerics with e.g. Spell domain, Time domain, Celerity domain, or the Cleric Righteous Wrath of the Faithful which replicates the extra attack (doesn't stack with Haste) while also granting generic stat bonuses. And of course, any Cleric can Miracle it.

[Chaosticket]

Not the right question then.
I meant Divine and Arcane magic.

I know the Mystic Theurge prestige can level both types simultaneously. Its hard to work with as it doesnt keep class features so its more about trading 3 Wizard levels for 13 Cleric levels. Specifically a second spell pool for Divine spells as you dont scale abilities and cant use armor with Arcane.

Arcane Hierophant is better as it keeps the Druids features scaling and basically gives you 13 wizard levels. Wild Shape+ haste+invisibility.

[Biffoniacus_Furiou]

You don't need to be able to cast both arcane and divine spells, especially on a gish. There are plenty of ways to add normally-arcane spells to your divine spell list or otherwise cast them as divine spells to buff yourself.

If you want to make an Arcane Hierophant, your BAB may suffer because Druid doesn't get Divine Power. If you do want to go this route, there are many ways to do it, I'd prefer maxing Druid abilities by going with any Elf race, Druid 8/ Suel Arcanamach 2/ Arcane Hierophant 10. That only gets +14 BAB, but it has Druid 18 spells, wild shape, and animal companion, max level Suel Arcanamach spellcasting, and you add a 12th level arcane caster's familiar benefits to your animal companion.

[Chaosticket]

I know raw BAB wont be as good, but animal forms with more attacks compensate somewhat. Its more about buffing. Adding Arcane spells and another pool means lots of buffs. Shield, Greater Mage Armor, Haste, and so on.

I heard about Bite of the (blank) series like Weretiger that gives an enhancement bonus to all physical stats especially a +12 to strength.

[atemu1234]

My old(est) build was a Sorcadin I posted a while back. Paladin 2 / Sorcerer 2 / Eidoloncer 2 / Spellsword 1 / Abjurant Champion 5 / Sacred Exorcist X.
TBH, in hindsight, it'd probably be easier just to be a Prestige Paladin 2 / Cleric X.

[Fouredged Sword]

A druid gish works really well with rollibar and karmeic strike. Stack strength and dex (tons of aoos) boosts from woldshape and bite of the x line. You have a smaller full attack than most gishes, but your single hit is much more powerful due to a strength in the 50s. Splattering anythingnthat dares to take a swing at you makes for a fun melee defense as well.
