My own tierlist:
Note: bias towards Wasp

Differences to vivafringe's tierlist:
- F-Tier Glasses vs. vivafringe's C-Tier
I got glasses + Inkwell, in a position where Inkwell could be protected, but died after I spawned into a corridor where the glasses were facing. The stratagy might be worse on Wasp since Magpie has enough space to avoid any corridors where glasses might be a weakness.
- B-Tier Seashell vs. vivafringe's C-Tier
Everytime I pick up seashell in the mid-late game, it survives for just long enough to get to another tool. But putting it lower is still chill because it is still somewhat dangerous.
- D-Tier Credit Card vs. vivafringe's A-Tier
Anytime any combo that provides a coin upon destruction somewhat too dangerous, especially when I get a silver coin in return. Obviously when you get a gold coin its solid, but its never guaranteed. I prefer seashell more than credit card, but I still take it when I feel that I can strategically take it to take the coin to advantage. But once your at 70+ points with Wasp, you get so many coins that a credit card isn't even useful.
My optimal combo is Inkwell + Candlebra, the damage potential is insane. Bonus points for staple and/or cross, they can clear any big hoard of enemies that usually stack because of wasp's small map size. Double Inkwell is definitely really solid, but with Wasp or in general, one of the Inkwell's gets taken out quickly, so when you have double Inkwell, make a plan instantly to replace one of them when they inevitably breaks.
With Wasp, killing a rat in a certain location matters a lot more than any other mob. For instance, if you have the best combo, Inkwell + Candelbra, staple and/or cross, picking up coins interrupts the combo. Since Wasp's map is so small, you really want to think about killing the enemies in the most optimal location so that you don't have to pick up. The worst maps are when your forced down a corridor to kill and in a good position in terms of weapons. Then, you have to pick up all of the usually grey coins down the corridor.
I agree with vivafringe not taking 1 gold coin + 2 silver coins weapons, their usefullness is mediocre than getting 2/3 gold coins. Obviously, getting 1 gold coin is better than 3 silvers but even 3 silvers have some usages, such as the mirror. I think clock is 1 coin, and I believe that its one of the best semi stable weapons, in the mid game
I probably will update this as I get higher scores.
