Not a weapon. But I find the Djinn's Curse really fun to use on mounts like the Unicorn. It greatly amplifies your airtime control without having to use Wings. Although doubtful to give up your leg slot for it.
I agree to this as well, I love the Shadowflame Weapons, if I can get either a Bow or the Knives, they usually let me take on the Mech bosses and a majority of Hardmode without too much trouble, even on Expert Mode.i've barely seen someone use the shadowflame weapons, they are very useful against the destroyer
You're supposed to get the Uzi before MegasharkWell, that's because the Uzi deals more damage but is slower at firing than the Megashark, but the Megashark does less damage, thoughhhhhh with it's fast speed, it makes it more powerful than the Uzi, so... Megashark is better than the Uzi, despite it having lower damage
