Everlasting Abilities gives the player the ability to retain various buffs without needing to carry around bottles of potions all the time. The Abilities come from random totems found throughout the world and are loaded up to the player via an Ability Bottle. The bottle should show up the first time you load the game with the mod installed but it can also be crafted.

Then if you find a totem you simply right-click with it in your hand and move it over in the ability bottle GUI.

You’ll be able to add things like fire resistance:

Strength:

And even flight!

Adding abilities requires a significant amount of XP that will return to you if you remove them. And some have multiple levels making your permanent buffs that much more impressive! This mod requires an additional API found here.
