Basically, summon wolf in two hotbar spots. Once you have 10 squirrels, put summon wolf in another hotbar slot. It comes up as the summon spell version while the other slot stays on Sciurine’s Rage. Cast it, 1 squirrel dies, 2 appear, totaling to 11. The number on the squirrel count icon is 11. Also, change the summon version back to whatever skill you want and they still remain as 11 summoned squirrels. And that extra little turd seems to follow his own rules and goes crazy nuts trying to solo things that are offscreen, which he can do… eventually. Most often when I’m just flying through the crowds of mobs and not paying attention, he’ll latch on to something regardless of what the other squirrels are doing.
Can’t say it’s not fun having 11 of them, but I saw the 10 squirrels 1 wolf bug, so I’m guessing it’s not intended.
Will edit in game log post here when I figure out how to make one.
