Transfigure

You attempt to turn one creature into another creature. For each Stamina you spend, you can affect a creature up to twice that value. When casting this on a willing creature, you do not need to make a Spell Contest. Make a Spell Contest. If they fail, they turn into an animal of your choice, pig, sheep, or chicken. If they tie, they turn into the animal for 1 round. If they succeed, they do not turn into an animal. They can repeat the contest at the end of each of their subsequent turns. The effect ends after 1 minute.
