Does “stack” = “buff”? (As in the description of War Equalizer or Malosi’s Special.) I am always perplexed by that language. If it means “buff”, please use that word. If it doesn’t mean buff, please tell me what “stack” means.
A stack is from a hero like Mireweave or Skadi. Each time they cast there special it applies a buff which gets better the more times you fire it.
So not all buffs clear in Equalizer Wars?
