Not sure if working as intended but I thought minions were not affected by the burn, hence not using any charges. First game with vlad I couldnt help but notice the charges maxed at 25 or quickly rise as I spelled through minion waves. By the time I was attacking champs I was maxed out. Problem?
Update: I was wrong, as somebody else stated it charges passively and as you use it, it consumes charges. Got it. Working wonderfully as intended. Just gotta say, THANK you for this item. It has made my long time favorite Vlad viable again. Please dont nerf it too hard.
