Hi, does anyone know and has noticed that when the opponent is at low health and you have Assassin mastery, ur champ should make more damage. I was playing against symbioid in AQ map 2 on day 5 with my 4* rank 5 King GROOT ( signature level 45) , and I have level 1 in Assassin ( 20 .0% Attack) the damage on basic attack was 222 per hit when the health of the opponent was very low , I am sure it was below 18% mark. Here is a video and a image. Not sure if it's working fine or not.
