Wiki states: at lvl2 imbue explode is 10d6 damage. It also explains that "Explodes for 10d6 + 1d6/2 AA levels of Fire damage in an AoE. The AoE his the target as well. DC vs Reflex of 10 + AA levels + hard DEX or INT mod (whichever is higher)."
What actually happens: You get a fireball spell that does 1d6 per caster level as a touch attack.
I don't think this makes sense, aside from the information on wiki being inaccurate. The main issue is that the attack now scales with the caster level, but why would an arcanist need another fireball spell they already have, and why would an archer need an attack that scales with arcane caster levels?
I'd appreciate any insight but this definitely broke my build and now I'm mean to everyone at my work lately.. =P
