So, while looking at the WD tree, it seems several skills specifically Mass Confusion, have the runed ability to summon a zombie dog, so if you picked up a passive skill to support your summons, but then used a skill like mass confuse, you could have zombie dogs AND and extra skill that you wouldn't have if you just initially picked zombie dogs?
I guess they would be weaker, because they are not runed. That might be the downfall.
Well i wonder if you did have the skill and runed for say fire dogs, then would the dogs resulting from Devolution(Runed Confusion) would benefit from the rune effect. Regardless i just threw together a build inspired by this idea.
