im going to try to break down what I think of her, lets see:
- Debuffs are not really the highest point of concern and shouldnt really be considered that great of a feat
- The way to trigger death effects without taking wounds is Nessas biggest plus, which is really good, cant lie, it is amazing when paired up with haunted synergy and Woad, but it doesnt really make it enough to be raised a tier, as Void Beacons can generate much more food with Woad, more than Nessa can even think of doing
- The Healing and Dps she does is very niche and cant compare to other monsters that can do similar feat, for example Gora.
- Rings are not enough to raise it tbh, it would just be too reliant on them to even work a little bit.
She is in the need of a rework and isnt suitable for anything other than D currently.
