Type of Feat: Spellcasting Prerequisite: Spellcraft 4 ranks, Warlock 1. Use: Automatic.

Your caster level for invocations increases by +4. This can't increase your caster level beyond your HD. For determining eldritch blast damage, you gain +2d6 damage if you are 4 or more caster levels below your hit dice or +1d6 damage if you are 2 or 3 caster levels below your hit dice. For example: A Warlock 11/Blackguard 4 would deal 8d6 damage while a Warlock 11/Blackguard 2 would deal 7d6 damage.
