Ring of the Mantle

The Ring of the Mantle is a bauble added by Botania. When worn, the player acquires the Haste and will be able to mine faster, at the cost of using Mana from a carried Mana Tablet whenever the player swings their arm while wearing the Ring.

To equip it, press the "B" key (by default) to open the Baubles inventory GUI, where the player can equip the Ring in a Ring slot.
