Blood Pool

You take 1d4 slashing damage to create a 5-foot by 5-foot pool of blood on the ground in an unoccupied space within range. The pool has the following properties:

• Difficult Terrain: The blood pool counts as difficult terrain for all creatures except you.
• Alertness: You can use your reaction to be alerted whenever a creature comes within 5 feet of the pool.
• Blood Spike: As a bonus action, you can command the pool to lash out with a blood spike, dealing 1d4 piercing damage to a single creature within 10 feet of the pool.
• Movement: As a bonus action, you can move the pool up to 20 feet to an unoccupied space within your line of sight.

The pool appears as a dark, viscous liquid that pulses with a faint, malevolent glow.
