This is a mod that has an anvil that provides you with the ability to add potion effects to your weapons.
It should work with most modded items like modded tridents, axes, swords & potions. This mod works in survival and has a crafting recipe to make it obtainable, but the recipe costs alot of iron + one sacrifical anvil.
A bonus feature of this mod is that you can remove and add effects to existing tipped arrows by putting the tipped arrow in the left side of the anvil and and potion in the slot next to it, and to wash the arrow you take a full water cauldron and right-click it while holding a tipped arrow.
