From publisher blurb:
A 3RD-LEVEL FIFTH EDITION ADVENTURE
How the Grick Stole Christmas is a 5th Edition adventure for three to five characters of 3rd to 4th level and optimized for four characters with an average party level (APL) of 3. A gang of mischievous gremlins trained a giant grick to tunnel into the town of Tinker’s Haven and stole Mother Midwinter’s magic sack of toys! They’ve taken it back to their hideout and are playing with their new toys while the townsfolk call on the adventurers for help!
This adventure fits into any existing campaign with a midwinter festival with only a few modifications and name changes. The adventure is designed so that characters can avoid most combat for a more comedic or light-hearted approach. As always, the GM determines the ambiance, and things can take a grim turn if desired.
