Another variation to try after you are high paragon level (meaning you have both points already in wis, wisdom arty, +16 wis gear) is to only take esf: evo and instead take psf: abj. The 100% IE is nice as well as the dispell ability. After testing if you still get implode DCs of still around 60-61ish (I don't remember the exact number off hand). Good trade off imo and I've liked it so far. Ultimately up to preference though.
Yeah that's the version I'll go for once it hits 80 I think (or if I build up the courage to suck up the XP hit earlier).
