Unstable Mutagen

You discovered or were given a secret to make your mutagens more unstable—but also more potent.

Benefit: Once per day, you can create an unstable mutagen. It is like a normal mutagen in most ways, but also gains a single benefit or hindrance due to its instability. Roll 1d6 to determine the result of the instability.
