Warpath of Gruumsh
In this level 3 adventure, the heroes face off against a band of orcs who live on islands in a pool of their orc god's blood.
Warpath of Gruumsh is part 2 of the Litany of Arrows adventure path, following up on the platinum-selling Castle of Corellon adventure. This can very easily be run as a standalone adventure.
Warpath of Gruumsh contains three versions of each full-color map (untagged, player's map and DM's Map), original artwork, one page of new magic items, and full entries on 6 new monsters, including mithral dragons and blood moon harpies.
