It would be cool to see how various season 3 familiars have their stats and effects modified as they level up. I want to know mostly about Ethereals, but any info would be helpful. Does Kero’Var’s 2% potency group buff scale as it levels up? If so, by how much per level?
I don't think anything about the procs scale. Just the personal buff stats, and the potency to self. I could be wrong, but that is what it looked like to me.
I was talking to someone in game who had a leveled up Clonlin Ethereal maxed who said the damage proc was doing about 1000, and his potency was around 50% (Level 8 familiar). I'm not sure, but if the damage procs scale and the group buff potency doesn't, one seems far better if leveling familiars up. Then again, if group potency scaled up it would be pretty broken. If anyone runs a test on a cheaper familiar to draw some conclusions, let me know.
