Just a Devil Fruit remover, it's very simple and there probably won't be any updates to the mod, except for one or two bugs that are reported.
(Unfortunately I don't know how to put images in Curseforge to illustrate the craft, I recommend you use JEI, otherwise try to understand this:
Slot0: Nothing Slot1: Glass Slot2: Nothing
Slot3: Glass Slot4: Diamond Slot5: Glass
Slot6: Glass Slot7: Kairoseki Slot8: Glass
Result: Remover Blade;
Slot0: Kairoseki Slot1: Glass Slot2: Kairoseki
Slot3: Kairoseki Slot4: Glass Slot5: Kairoseki
Slot6: Kairoseki Slot7: Kairoseki Slot8: Kairoseki
Result: Remover Body.
Remover Blade + Remover Body =
Devilfruit Remover.)
