Advanced Boss Rush Boost Potion

Only Alchemy Masters can make this potion, which increases your Boss Damage by 20% for 40 minutes.

Caution
Normally, only 1 potion can be used at a time, but Alchemists can use 2 if they are of different types.
However, even Alchemists cannot use 2 of the same potions at once, and Great Hero Boost Potions, Penetrating Boost Potions, and Great Blessing Potions cannot be used together.
