Charisma for warlocks (NWN2)
 

I don't like posting two topics in rapid succession, but I couldn't fit this in with my other post.

When creating a warlock, the game recommends high Charisma, but I don't know what bonus that really gives you. Clearly you don't get more spells per day, since you already can cast at will. Presumably each level of invocations requires a certain Charisma score for access - but there are only four levels, so I can get by with a score of 14? Or does the Charisma score have to match up to the "Equivalent Spell Level" thing in each invocation's description? And beyond that, does high Charisma confer any other class-specific bonuses?
