[Alchemy Lv 42] tooltip lists the following for the Carnage recipe:
1 Oil of Corruption
7 Pure Powder Reagent
2 Tiger Mushroom
3 Trace of the Earth
2 Spirit's Leaf

I used that recipe and was successful but my higher alchemy might have been the reason. Anyone else use this recipe and was successful?

Thanks for the report. I've corrected the number of the ingredients.

Alchemy master 7 and was able to use 1 special tiger mushroom in place of 2 normals
