Alchemy Meisters can make this potion, which increases your attack damage by 10% 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 Boss Rush's Boost Potions, Penetrating Boost Potions, and Great Blessing Potions cannot be used together. The cooldown is 50 minutes.
