Wrath of the Wyvern: Skyfire Showdown

From publisher blurb:

Wrath of the Wyvern is an epic one-shot adventure involving brutal combat as the players are tasked with hunting the last stone-scaled Wyvern in a cold, muddy region known as the Umbral Highlands.

It features 6 comic-style battlemaps, 5 new stat blocks, which, together with the tokens and music and ambient audio, will enhance your playing experience.

The adventure is designed for the following levels: 5 to 8.
The gamemaster can quickly adapt the experience to the level of the players by adjusting stat blocks or reducing or increasing enemy numbers and encounters.
