Arcane Disciple Feat

[relytdan]

Warlock does its Invocation spell like abilities qualify for Arcane Disciple?

[Chronos]

No, because Arcane Disciple requires "able to cast arcane spells", and a warlock can't. Even if they did qualify, it wouldn't do any good, because they don't have a class spell list, nor any way to learn spells from it.

As Chronos mentioned, Arcane Disciple has, as a prereq, "able to cast arcane spells," and as a benefit it adds a domain's spells to your arcane spell list.

Complete Arcane specifies (under "Warlocks and Prestige Classes") that:
A warlock cannot qualify for prestige classes with spellcasting level requirements, as he never actually learns to cast spells. However, prestige classes with caster level requirements, such as the acolyte of the skin, are well suited to the warlock. A warlock’s caster level for his invocations fulfills this requirement.(Emphasis added.)

In other words, although a Warlock's caster level for invocations may qualify him for things which require a caster level, it will not qualify him for anything that actually requires the ability to cast spells, such as Arcane Disciple.

And as Chronos mentioned, without the ability to cast spells, adding domain spells to your nonexistent list does precisely zip.

Well you could use it for certain prestige classes. Effigy Master for example would work very well in this case. I'd certainly talk to the DM about getting that approved if that's your aim, since it's not that ridiculously OP.

What's more interesting is the Sandshaper prestige class, which a warlock can qualify for, and which adds a number of spells to your spells known. You still can't actually cast them, but I think it would mean that you'd now be able to use wands of those spells without UMD.
