Eviter is able to be toggled on and off.

Know no Pain and Stalemate do not receive this benefit, meaning that if you have both equipped, you can never toggle between which you would rather be using at any given moment.

Toggling Eviter on and off does not allow you to use another parry under it. At least, that's not how it works according to Dev. It just turns it off.

..That's incredibly dumb.

If you have multiple parries, being able to turn one off and enable another should be feasible. You're spending slots for both. Having them both be active at the same time is a different matter entirely to just.. Toggle: Off Eviter and Toggle: On Know No Pain.

This is not a bug.
