The Ability Stones mod adds a series of stones to apply certain effects for 3 minutes at a time. The new Magical Dust Ore is the key to crafting the stones. It allows you to create Mundane Stones that the effects can be applied to as well as powers the stones when you craft them.

Then you can combine potions to the mundane stones in the Ability Infuser with the magical dust to create the ability stones.

When activated these stones will allow you to resist fire:

Breathe underwater:

Jump higher:

And you can even see at night or be invisible altogether!

You can also create an advanced infuser that allows you to combine effects into one stone. Check out the wiki here for a list of possible combinations.
