Ras Nsi with the Ring of Winter

Ras Nsi is fallen member of the Barae, a powerful group of paladins that worship and serve Obtao. He was infamous for seeking bloody and violent revenge against the Eshowe tribe of Chult and for the creation of the majority of the undead that roam that land. In the Tomb of Annihilation, he is in a weakened form due to the Death Curse.

In my campaign he survived and managed to acquire the Ring of Winter, a powerful artifact that gives creatures dominion over the cold. Contained within is the stat block of an end-game Ras Nsi battle, balanced for players in the fourth tier of gameplay. Additionally, a battle map of his inner palace is included as part of this product.
