[Haunted Evil Pajamas]

You can proc stalemate from behind if the attack is from more than 1 tile away. The easiest way to test this is with couloir. I've been told this has been a bug for a long time but I haven't noticed it's been reported, if it has been reported you can point a metaphorical gun at me.

How to replicate: Stand behind someone with stalemate within 2 range or farther and use a basic attack with a sword, spear, or axe that can hit them. This can be done with couloir, pierce linker, crash potions, a mutated bow or something.

Note: This does not apply to evitir, that works normally.

This has been brought up quite a few times in the past, with Dev's response being:

It's not a bug, Stalemate can only be bypassed in the tile directly behind the Black Knight.

Changes to this interaction would be better in Balance Fu, unless Dev changed his mind about it being a bug.

Just as a note, Ice Point Guard functions in the exact same way.
