yeah. i just think it was an insanely silly claim to make, considering it IS fantasy. maybe that one hand is weakened, meaning you hit less hard when holding onto a sword with just that hand, but your other
good hand adds enough strength and stability to stay effective with two-handers

.
I get that it is fantasy, but even in a fantasy world there needs to be some semblance of consistency (or a declaration that nothing is consistent...which is okay too, but not a game that I'd buy).
In this case, the combination of issues I experienced, if by design, would be (in my opinion) [censored]:
- Only one combat skill significantly reduced
- Absolutely no indication of what it was... anywhere
- No guidance on how to discover what the issue is
- Expectation that one will just chug potions to see what makes it go away
Game design needs to balance fantasy world and its rules with helping the player understand/be aware of what is happening.
In this case its a bug, so we can stop sweatpumping this.
