Thessaltrice

Thessaltrices were one of the four known thessalmonsters, a species of crossbred hybrid creatures. A thessaltrice was the result of crossbreeding a thessalhydra and a cockatrice.

Combat
Each of the serpentine heads acted independently and injected a poison with each bite.

Uses
Juvenile thessaltrices were sometimes used as guards. Thessaltrice eggs were worth up to 5,000 gp and a live juvenile up to 10,000 gp.
