...genin...
...hard to keep alive...
...as a force fielder...
*Brain Asplode*
Well... they're also silly looking. I have my vanity.
But I've also tried this build before, and I found the difference between using Genin+Jounin+Oni, and just using Jounin+Oni, is that all 3 of my henchmen usually survive every battle, so I don't have to re-summon very often. That just saves a lot of endurance, so I can keep on fighting instead of having rest every few minutes.
That, and 6 force fields are much less a hassle to maintain than 12.
Nobody is answering my core question though: which of the three options is better if I want my Jounin to kill stuff fast.
1)- Edict of the Master: Acc/Dam, Acc/End, Acc/Dam/End, +5% Def, ... then Achilles Heel Def Debuff, Chance for -20% Damage Resist
2) - Edict of the Master: Acc/Dam, Acc/End, Acc/Dam/End, +5% Def, ... then Touch of the Lady Gray Def Debuff, Chance for Negative Damage
3) - Edict of the Master: Acc/Dam, Acc/End, +5% Def, ... then Commanding Presence Acc/Dam, Acc/End, Acc/Dam/End
Can't decide whether to slot on Def Debuff or not. Can't decide whether Achilles Heel is worth it. Can't decide whether the Lady Gray proc is worth using a slot for either.
In the first two cases, using level 20 IO's (because I'm still only level 21), I get 1.45 Accuracy and only +28% damage. The real question is whether dealing a side damage like Negative will help me against enemies that strongly resist lethal damage. Or would Achilles Heel help me more? Or should I just not worry about it and go all out Lethal?
Honestly at that level your better with DO's and then SO's when you ding next level for improved damage.
As to the specials, I've no idea as I've yet to try any of them with this set, or any MM set I think 
I do prefer the prospect of the -Res over a presumably weak-ish occasional extra damage hitting.
I'm trying to figure out the best way to get the most damage out of my Jounin. I'm not considering any purples just yet (she's only level 21 so far). I've been trying using the Achilles Heel proc, since most of the sword attacks are def-debuff, but I'm not really seeing phenomenal results from that.
Should I just frankenslot for damage and accuracy? Is the Touch of Lady Gray (chance to deal negative damage) proc worth applying?
One of my slots is reserved for the Edict of the Master +5% defense proc. Can't put it on Genin because I'm skipping them. I can do a Mids later if it's necessary. Basically she's a Ninjas/FF MM focused on trying to max out defense on her pets, but only taking the top 3 pets. (I find Genin are just too hard to keep alive when you've only got Medicine pool as a heal power.)
