WorldGrower:Ghoul Transformation

Ghouls are people that need human meat to survive.
You can become a ghoul by eating human meat.

When you become a ghoul, you require human meat to continue functioning.
It's possible to restore your human meat level by eating human meat.
Once the human meat level gets low, the ghoul's energy gets drained.

As a ghoul, you count as undead for all spell and item effects.
As an undead, you don't need to eat or drink, except for human meat.
