A Sons of Gruumsh Forgotten Realms Web Enhancement
Sons of Gruumsh is a FORGOTTEN REALMS adventure for 4th-level
characters set in the Moonsea region of Faerûn. Several scions of the great families have disappeared from the city of Melvaunt, and the player characters (PCs) have been recruited to find and rescue them. Their investigations lead them north into Thar, where they discover an orc army massing for an attack. At that point, it’s up to the characters to carry out their original mission, as well as foil the plans of the orc adept Jurrg and her orog companions.
Tougher Sons of Gruumsh provides all the adjustments required to make Sons of Gruumsh suitable for 8th-level characters. As in the adventure, appropriate miniatures for all adversaries are suggested as part of the creature statistics blocks.
