It's been a busy week around the household. Boating on Sunday, Michigan Adventure on Monday. 3D Printer showed up on Tuesday, so I need to play catch-up. Here's another monster that shows up in the Stonemire region:
Hit Dice: 1d4
Armor Class: 3  or 7 
Attacks: Bite (1d6)
Saving Throw: 18
Move: 18 (swim)
*Skullfish are difficult to hit with any weapon that isn't piercing. The better armor class is when someone is not using a piercing weapon (like a spear or trident)
Skullfish are about the size of a sunfish or crappie. They derive their name from the exposed skull bones. They have no eyes, and no holes for eyes. The skin and muscles attach at the base of the skull giving these fish a distinct, horrifying look. They travel in schools of 10 to 50, and relentlessly attack anything that moves with their tiny dagger-like teeth.
