Belt of Four Elements (Patreon)

Wondrous item, very rare (requires attunement by a monk)

This belt is made from stone plates harvested from the Elemental Plane of Earth. In it are four gemstones, which are each attuned to and associated with a different element and damage type: air (lightning), earth (thunder), fire (fire), and water (cold). When found, the belt's planar energy is channeled through one of these gemstones.

While wearing the belt, you gain resistance to the channeled gem's associated damage type and deal an extra 1d4 damage of that same type to any target you hit with a melee attack. Whenever you use an action, bonus action, or reaction to spend 1 or more ki points, you can choose to shift its planar energy to a different gem of your choice.

The belt is merely a tool to deepen our connection to the elements, not a source of power. Everything we see is made from these elements: the fire that keeps us warm, the air we breathe, the water we drink, and the earth we stand upon. To achieve true enlightenment, we must strive to know the elements as we know ourselves, because it is only then that we may begin to understand our world and what it means to be Material.
