How about a dip into cleric? I'm considering doing that so my kineticist can use curing and restoring wands (I think I'm right about how that works). He'll be doing a lot of the healing for the party.
is there no bard, witch, ranger, paladin, skald, oracle, cleric, inquisitor, alchemist, etc in the party that can use the wands already?
Cause it's a very minor boon being able to use CLW wand, and a pretty big loss in delaying your kineticist stuff.
I played a hydrokineticist who took the kinetic fist talent and a 1-level dip into brawler. He went around punching people with his water fists. Worked pretty well.
I never understood the annilater surely the blasts scaling damage outscales the .5 con damage?
I would strongly recommend just sticking with the Kineticist. There's not really much you can get from another class that won't beat out sticking with Kineticist for the good wild talents and all the scaling that is built into the class (elemental overflow, your kinetic blast damage, and infusion specialization all scale to your level and are important).
Evangelist is probably fine though.
