When a nearby unit it's damage with loss of life type of damage, the Adept unit doesn't gains any basic attack. It shouldn't since it doesn't takes any damage, but hp loss.
I know, but I used a basic attack so it wasn't described that way. Maybe Attak: Loss of Life should say "if target is damaged, it instead loses that many hp".
Poxbase defines what Loss of Life is, so i'd assume the game defines what it is as well. https://poxbase.com/ability/522
