Reanimated Familiar

A necromancer's reanimated pet frog.
Raised in the age of Netheral using lost magics the pet has an Int of 5 and is able to bond with anyone it chooses as a familiar. During Netheralese time cycle and at times when the bonded one is mentally incapacitated the frog is able to take over just like it was the master. When doing so the bonded one is considered to have the water breathing and jump spells active upon them.
