Aspect Tattoo

You scribe a tattoo on a willing creature's skin that holds a portion of an animal's energy and ability. A creature can only hold one aspect tattoo at a time; scribing another eliminates the previous one. The animal being represented must be present when the aspect tattoo is created.

The recipient of the tattoo can activate the tattoo's effect as a bonus action. Once the tattoo is scribed, it remains until the effect is activated.

The known tattoos are as follows

Badger: The recipient goes into a battle frenzy, gaining tactical advantage on melee attacks for 1 minute.

Bear: The recipient's Strength score increases to 19 for 10 minutes.

Cheetah: The recipient's speed increases to 60 feet for 1 minute, and opportunity attacks against the recipient have tactical disadvantage.

Panther: The recipient gains tactical advantage on Stealth checks for 10 minutes.

Other animal tattoos could be discovered that grant different powers.
