Another fourth dimensional and powerful take.

Remove/change the curse effect and instead make it so all status effects but slows halve healing from sustain. Burn, poison, bleed, the whole nine yards.

Occult and illusion shouldn't be the only trees capable of contesting the sustain meta.

(Just a suggestion I haven't fought anyone with sustain but I've seen some sins out there.)

most of the point of curse is countering sustain, so I think having them all do the same amount would have all the other (more popular) status effects stealing its thunder. I think it'd be better if they all reduced sustain by 25%-ish, instead, but other than that, I totally agree that sustain needs more counters.

That's kinda the point. If curse's only point is countering healing, then it's either dead weight or necessary as a status effect depending on who you face. It's better off being a part of status effects as a whole and giving curse a new identity.

ohh, I see. I think that could be cool, especially since the curse effect's never really felt worth the difficulty of landing distort in a real fight. do you have any ideas of what to replace it with? personally, my only suggestion would be removing the damage dealt to the target over the duration of the status effect from their max hp for the rest of the round, similar to how black knife tiche works in elden ring. 

that might be a bit op, though, so take my suggestion with a grain of salt, lol.
