First I'd like to ask about Death Touch drops by the Deathitude/Super Death monsters.
Currently confirmed that Level 14 drops from all Super Death monster, Ultimate Super Death as well as Un Death.
Level 17 and 20 are not known, needing confirmation.
Edit - Been trying to farm Un Death, got a drop of level 17 and 20 Death Touch.
Level 14 and 20 Death Touch drop from Ultimate Super Death.
Final Summary: All levels Death Touch drops from all Super Death monsters.
