Great points and thank you!
- Whetstone is tricky because it's hard to make it not too OP but I do like the idea of scaling chance based on number of swords in a non-hit match. Keep an eye out after I test it carefully.
- Yeah in the demo, Arja doesn't come with any explanation. I'll bring a full-build mechanic across, which is a short Zerker intro to explain how arrows are different from swords. They also don't pierce but the animation implies they too. It was a visual choice that's become quite confusing, so I'll patch that first so any arrows that overkill hit the walls, and hit arrows don't.
Thanks for the spot on questions and feedback!
