Syrik's Drunken Sailing
Invocation Savant (Warlock)
Your power as an invoker is so great that parts of your power have increased while using other skills.
Prerequisites: Eldritch blast class feature, Spellcraft 5 ranks
Benefit: Your warlock level is increased by 4, up to a maximum of your HD, for the purposes of caster level, invocation save DCs, and Eldritch Blast damage. If your HD is not high enough to gain the full benefit of this feat, it will increase when you gain another HD that is not from the warlock class until you have gained the full benefit. So a warlock 5/rogue 2 with this feat casts her invocations as a level 7 warlock, and has an eldritch blast that deals 4d6 damage. If she later gains another level of rogue (making her warlock 5/rogue 3) her caster level, invocation save DCs and eldritch blast are all calculated as if she were a warlock 8. This does not grant any other abilities or benefits from the warlock class.
