Who hasn't thought about throwing the "ultimate" and hitting barrels or mobs that are further away from the boss?
As a solution, I think it would be nice to edit this special ability, that the last one only targets nearest enemies and enemies (in this case, if you are between 2 mobs and the boss, just get close to the boss to hit him and you don't end up hitting a mob that has 2% life and you waste the shot
If it is possible that it also aims in a smaller area that the enemy with more life falls the shot
