Bug: Duct tape blocks bows' effect from arrows behind it, even though bow specifically says only affect arrows
Edit: Also scratch doesn't count as damage for some reason I tested it against the rooster
The scratch bit is intentional.
I can't see how it is because it obviously deals damage.
The design of scratch as far as I can tell is it is a low cost low damage alternative to high damage seeing as those things proc effects and scratch doesn't.
