Currently it seems that if you trigger a glancing strike while simultaneously triggering "Resist" on a spell, (Untested on basic attacks) it does not lower momentum by 1.

I've noticed this a lot during my playthrough as a summoner, that casting a spell that is resisted will drop your momentum to 3 instead of 4, as intended. Unable to cast the spell a second time that round. However if the resisted spell triggers GLANCING, then you remain at 4m after the spell and can cast it a second time. My Youkai make this happen fairly often. Untested if it works with players as well, but I assume it does.

Steps to reproduce:
1: Make sure the enemy will resist your element of choice enough to proc "Resist!"
2: Hit them with the spell.
3: Hit them with the spell again until it triggers "Glancing"
4: Note the momentum discrepancy between steps two and three.

This is just a quirk of how the glancing system works; you also don't gain momentum for hitting a weakness, because glances are technically a 'miss'.
