The final variant quest is badly designed
There are two paths with some bad designs. The first is the caustic temper path with bleed vulnerability and the second is the biohazard with bleed vulnerability. To start with the caustic temper path, there is only ONE option. Hulk is the only choice if you want to deal any damage. Using vision (the only other poison immune) it takes around 2000 hits. Biohazard isn’t that bad with vision, but it still takes around 150 hits with vision. The major problem is putting bleed vulnerability on these paths instead of dash vulnerability. This would make the fights much more bearable
