Which IV for Brave Hector

I mean... whaaaaat do you want him to do? A mixed tank doesn't mind the loss in physical bulk cause he crazy tanky anyways
Res tank the answer is obvious
Offensive powerhouse I mean he has Bf, 54 ark with weapon and qr 5 built in just give him the atk iv ooooooor like wait and see if you don't pull another...

I wouldn't use -Def.

I also have neutral and +Res -HP. I can't make up my mind either. Neutral might be better as speed is clearly his only dump stat.

he is very slow so he is going to tank hits many times so +res would be appreciated. -hp is his second best bane so its fine. -def really hurts him and the attack boon is not important enough to go for it.

-> +res is way better than neutral
