Are there plans to have an equivalent of the pain threshold from Symbaroum translated to the 5e version? Maybe as an optional rule?
A pain/Wound threshold could work in the 5e version, or even something additional triggered on a crit, with consequences like a small risk of dropping to zero hit points, stunned, or knock down etc. There’s an equivalent system shock rule in the DMG, but it’s very much tied to the high heroic curve of vanilla 5e. Something a little more grounded may be appropriate, less of a super hero curve?
Situational options like receiving damage when surprised or incapacitated could also be a trigger for effects similar to the Symbaroum pain threshold.
I like the heroic 5e attritional combat, but sometimes if the setting allows, as I think Symbaroum does, it’s fun to add a touch more threat to the game.
