So it seems to be an annual tradition in my D&D game that I run a holiday special, complete with a goofy Doctor-Seuss-ish poem and some seasonal themes. Last year our heroes got into a flying-sleigh-fight with a bad guy who wanted to prevent presents from getting to good boys and girls, and also battled a squad of snow golems (snolems for short).
This time there were Christmas treants hung with alchemical globes, each of which produced a different effect. And it's not over yet.
Here, Kaia, in rock elemental form, digs a hole while angry Christmas treants approach. Frances casts spells and Reginald skulks among the trees. Zylphia is just outside the bottom of the shot, hacking one up with a sword.
