Forgotten Realms: Gi of the Elemental Master for D&D 5E

In my Forgotten Realms game, I'm creating some magic items to seed my campaign with:

Decades ago, a Master of Dragons whose ki had been corrupted, hid this powerful gi away. Only recently was it discovered to be hidden in the land of Chult, within the Peaks of Flame. Those seeking it must endure the jungle, the Peaks, the ancestor spirits set to guard it and possibly the Dragon of the Peaks, itself.

GI OF THE ELEMENTAL MASTER
Wondrous item, legendary (requires attunement by a monk)

This traditional gi is made from golden silk and the shoulders are adorned with scales freely given by the gold dragon, Nyrosaki of Kara-Tur.

You gain these benefits while wearing the gi:

• If you aren't wearing armor, your AC increases by 2.

• Your maximum ki points you can spend to cast a spell increases by 2.• Your ki save DC by 2.

• You martial arts attack bonus and damage bonus each increases by 2.
