From publisher blurb:
Two Heads Are Better Than One is a short adventure designed by Hannah Rose for five 4th-level characters. It focuses on exploration and combat. Scaling options are included for weaker or stonger parties. The adventure also includes Plot Hooks to help the GM add this one-shot to their own campaign.
Background
The elven mage Albern, self-styled "the Ingenious," was outlawed from his academy for unlawful experimentation with the dead. Bitter and angry, he fled toa nearby cave and vowed to continue his experiments until he could create a creature powerful enough to enact revenge upon his former colleagues.
Albern's attempt to create a homemade zombie ettin by attaching an additional hear to an ogre zombie was technically successful - but unfortunately for him, the enhanced zombie killed him in a fit of mindless rage.
