Using 7433 Tiles on Windows. Shockers are supposed to shock you when you hit them with something that conducts electricity. I’ve seen the term “zapback” being thrown around and I assume that is what this refers to. It also seems to be happening with bows, however. No matter how far away the shot is from it always zaps my character. I didn’t notice it for quite a while though, and looking at the bows I’ve accumulated I assume it’s because this one conducts electricity where the others didn’t. That said, the arrow is no longer touching the player once it is shot so this shouldn’t happen.
The bow in question is the Survivor’s Fighting Bow from the Cataclysm++ mod. It may affect other ranged weapons that conduct electricity as well; I haven’t tried it.
