I noticed during "Do Animatronics dream of Automatic Weapons" 18 Desert, the NPC Weapon Smiths hit for 400-700 damage, not a charge. If it was a charge it doesn't display the charging icon. I got dropped in about 10 seconds. Without Invuln on, those would hit me for 1/4 of my HP. Submitted a bug, but figured I'd post screenie here. I don't think it was every mob of Weapon Smiths either, that I noticed...

I've hit this issue as well.
I'm Dual Blades, with Invuln and Ego sprites + Advantage if anyone's curious.
