[GAMEPLAY] Brand's passive kills tryndamere under ultimate

I'm not sure how often it happens, but I definitely saw it in my last game :

Tryndamere was fighting against Brand, he was about to die, activated his ultimate (the skill went on cool down and we could hear the sound of its activation (tryndamere's scream)), but he died right after, as if he hadn't activated it.

I believe it was Brand's passive that killed him because of the timing (he died like one second after Brand's last skill, just after reaching 1 hp)

I'm sorry I don't know the exact way to trigger this bug, but I hope my explanation will help you fix it !
