I've got some crazy bug report for ya! Using the latest Tmod (v0.9.0.2), Thorium (1.2.13.4), Prefixes for Enemies (v1.2.0b), and Class Based RPG (v0.4.2.2) I have found a strange issue during multiplayer. I obtained a Danger Dual-shot bow from a regular slime, and later on a rare slime. Never used it before, thought it would fire two shots (which it did) and gave it a go. Well, every time I fire the bow I get a few items at random, always guaranteed a drill. Here's a picture of some stuff I got, Thorium exclusive items only.

In seperate shots, I got Feather Foe and Danger Drill, Flight Hat and Danger Drill (2), Danger Shard and Danger Drill, Danger Greaves and Danger Drill, etc. It seems to be mainly flight and danger items.
Hopefully this is enough information to figure out the issue with the bow. The Bow dropping on rare enemies 100% seems like a Prefixes for Enemies issue since they aren't dropping tokens at the start of the game. I don't get why regular enemies occasionally drop randomly stacked Thorium items, though.
Edit- My friend and I may have just saw a slime drop the bow as well. We just noticed it where a pile of slime gel was, where slimes were being killed off.
Edit 2- A regular zombie just dropped a Steel Chestplate. Now I'm really curious as to what's going wrong here lol.
Edit 3- All regular ocean mobs dropped Shade Master's Treads. Anywhere from 1-4 in a stack. Can't reach the abyss so I can't confirm on those mobs.
