I struggled through the debuff in one of my playthroughs. It was very doable actually. I think we are afraid of the words "Can't" and "Reduced" a lot, while in fact those would go mostly unnoticed.
Also, there should be a way to remove it. I think there is a spell in DND that can remove curses. This can be a good way to deal with the drawback, if they implement it.
There is :
- Remove Curse : 3th level spell and casters only get access to it at Level 5 (others at Level 9).
- Greater Restoration : 5th level spell and casters only get access to it at Level 9.
If it's actually a curse, both could apply. If not, Greater Restoration might be the only solution.
Considering how strong of a debuff this is, I would agree that it would be nice to, at least, be able to reduce the debuff afterward, if not remove it entirely.
Or reduce the debuff from the get-go (if it's going to be permanent).
Is Remove Curse already in the game? SH should have it at least at Level 5.
Has someone tried?
