Ryfter
Terrarian
A new item, craftable from every existing expert mode boss drop, (SoC, Boc, Hive pack, etc...) into one that can do all these abitilies, and maybe a toggle next to the inventory in case you want to disable some of them, as SoC can be annoying sometimes, either it could be all of them combined in one craft, or more like the ankh charm, where you combine them by groups
