Puddle of Blood: As an action, you create a large pool of blood on the floor in a 10 foot space that you can see within 60 feet.

The Puddle of Blood is considered difficult terrain for creatures other than yourself. 

You can have up to 3 puddles active at one time, which last for 1 minute. During that time, if you are in a Puddle, you can teleport from puddle to puddle as a Bonus Action. This does not trigger attacks of opportunity
