Another one of those dumb combo ideas

Corrupted soul - Cloaking (Soul Harvest) + Magic circle (Material Synthesis) consumed

increase mana acquisition by 100%

cloaking is always active

lose 5% of max health every 5 seconds

you can only recover hp from killing enemies

increase hp recovery for each enemy killed by 0.01% per 50% mana acquisition.

If max level reached then: lose 6% of max health every 5 seconds

atk increase 1.1x per 60% mana acquisition atk amplify 1.05x per 60% mana acquisition magic cd - 15%

(abyss is bad here, but this combo is even worse, lol)
