When you choose to use one of the tavern features like 30% attack bonus for 24hrs, you also get a second window come up after which offers a double boost for diamonds.
Does that mean the second boost for diamonds is added to the first boost - so 60% boost in this case? Or does it add a second boost o nce the 1st one has expired?
Also, is it 30% boost on your base att/def bonus, so (100% base att/def = 130%) followed by the second boost of what will be 130% with 30% on top of that? or 30% on top of the base att/def, so another 30% in this example giving you 160% in all.
