Empress of Light
Anyways, the name already suggests what the weapon is – a combination of the Meowmere and the Whoopee Cushion (or the Fart in a Jar). This will be crafted at a Mythril/Orichalcum Anvil and now you have the very annoying Fartmere! At least now you what to do when you have a spare Whoopee Cushion and a duplicate Meowmere in your chests.
The Fartmere will be a weapon with no additional stat increase, but has the "Annoying" dial at 11/10; not only will the Meowmere cats will still meow every time they bounce/explode, but a (hopefully bass-boosted) Whoopee Cushion fart sound will also play whenever they bounce!
With the 1.4 addition of the toilets' ability to shoot out feces and the upcoming Fart Kart, I hope this can get into the game as yet another joke item. Thanks for reading!
