PokeManiac Is Back!
But where are the sub-forums?
Imagine if Shaman is attacking a builder Hut in the corner of Base, it will take 10s for him, while other troops can take it down for about 4s.
About his range... When you deploy him, he selects an ally to heal and go to buildings until he is 3 tiles away from the aimed one. So he will take down all (I think there can be max. 5) buildings in 5 tiles range at a time (after 10s).
