Yeah i wanna know too. It seems i kill a soldier and i don't gain any basic attack damage so im guessing it's guardians but 15 kills is a bit extreme but i could probably do it. Wish they'd explain also im curious as to whether or not your gems work under your relics? It seems stupid buying a gem for 5k to put in a relic when you could just buy a 200 one.
Reppin' the underused and underrated on every game I play.
