Item discovery is not affected by your level, it is in independent stat.

Your base item discovery is 100. It can be increased in three ways. Gaining liquid humanity (the number at the top left) adds to your item discovery. Each humanity add a little more up to 10, at which it adds 110 extra discovery. Alternately it can be increased by using one of two items, the Covetous Silver Serpent Ring or the Symbol of Avarice, which both add 200 discovery. These item will stack with humanity, but they will not stack with each other, making the highest possible discovery rating 410.

This mechanic is explained on the Humanity Mechanic page.
