Well, as I see it, pointing 5 points into Ice summon, silver charge summon him, respec, 5 points into cloud strike, silver summon him, and then respec, 5 points into Berserk Stance. Now I have 2 pets that will stay with me regardless of zoning or teleporting. ALSO, this makes it where enemies DO NOT TARGET the Ice summon.
Seems pretty broken / exploitable to me.
