Boosters
Boosters are consumable items that can be found in chests, given as rewards from doing bounties or bought from the Mat/Booster shop in The Acropolis for Ancient Coins. There are many types of boosters, some give stat boosts while others provide special effects. Note that boosters which provide special effects scale with the Hero's level, the formula is the boost listed below +2*lvl, so at lvl 99 the boost will be the value listed below +198%. Boosters of different tiers (e.g. Attack II and Attack III) will stack effect, while boosters of the same tier (e.g. multiple Attack II's) will stack duration.
