It would work like this: You prep a Fortitude Tonic and buy another one. When you have around 40 corrosion on Horatio and thus 40 weakening on you, you take one Tonic and got 40 damage per attack+ the nerfed damage you got before. Repeat after another 40 corrosions and you have 80 damage per attack and Horatio has 20 (when you still have resists).
Or is corrosion maxed at some point? Monk is excellent at stacking corrosion fast, so I dont care about any other damage source


I am still not sure if this is possible but it would be a cool achievement
