From Drifter's Wiki

Reagents are consumable items generally found as loot on animals that enhance skills. Each class has two abilities that can utilize reagents. To use them, they must be equipped to a belt bar slot and then enabled by the little check box. You will see the stack number appear on the corresponding ability. The power of the reagent increases based on the level of the monster it drops from.
