Metamorph:
You can change into 1 random creature (+1 additional random creature per 7 levels advanced).
It will take 7 days to complete the transformation and gain all abilities of that creature. When changing into a random creature, the transformation cannot be stopped until complete.
To reverse this effect, and become yourself again, will take 7 days (reversing the transformation cannot be stopped until complete).
Roll on "Regions, Random Determination of" in the R section of the Basic Rules Book to roll up a random creature you will be able to change into.
