What about increasing difficulty corruption? I mean combine all of the ideas like:
- below light corruption only max HP and stamina gets reduced as it is right now
- on light corruption you lose strength and (real) accuracy while still losing HP and stamina
- on medium corruption you slow down and lose encumbrance (I do not have better ideas right now). This is an added “bonus”, you still losing accuracy, strength, HP and stamina.
- on heavy corruption and beyond on top of the former losses you start to lose your actual perks.
