When I was playing Cinder405 he/she Equipped Cloak of Long Knives to Ospryan Valkyrie and it'll created impassable shadow clones in the starting 3-6 rounds.
If you use Bone Circle: Lich twice you'll lose your +1 range permanently on previously affected champions from the boon. You could possibly trouble shoot it by switching to skeletons and then back to Lich, but I'm not sure that's WAI. Edit... Actually I'm having trouble gaining the 1range alone from using it once.
