@GunnerMcGrathAre warlock invocation prerequisites by class level or character level? Book doesn’t specify. Thanks! The intent is that a level prerequisite in a warlock invocation refers to warlock level.

@GunnerMcGrath @mikemearlsAwesome, thanks! @mikemearls said otherwise on his AMA but mentioned you were the rules expert. =) Yours makes more sense. Yeah, any official ruling is made or approved by me.

@chadkoh(Sorry for the lateness) I assume this is also the intent for level-based damage? Cantrip damage is based on character level, not class level.
