ASol passive executes minions under or left below 25hp.
It’s literally useless past lvl4 though so I don’t even know why it’s still there lmao
Also ASol E isn’t interrupted if he has a shield to block damage for him. His HP bar needs to be altered which means that with mountain soul, ASol Q/E’s can be even harder to stop than they sometimes already are.
Kai'Sa Q also does something similar where it executes minions at a certain HP point, this is to help with last hitting because otherwise it would be much harder to use Q to farm.
