Phase Monster

The phase monster attacks with its horns and its claws.

Melee Weapon Attack: +6 to hit reach 5 ft. one target. Hit: 8 (2d4 + 3) bludgeoning damage. If the target is a creature and the phase monster moves at least 20 feet straight towards the target before the attack the target takes an additional 5 (2d4) bludgeoning damage and makes a DC 14 Strength saving throw falling prone on a failure.

Melee Weapon Attack: +6 to hit reach 5 ft. one target. Hit: 8 (2d4 + 3) slashing damage plus an additional 5 (2d4) slashing damage if the target is prone.

The phase monster unleashes a horrific screech. Each creature within 60 feet that can hear it makes a DC 13 Wisdom saving throw. On a failure it is frightened for 1 minute. While frightened by Blood-Curdling Scream a creature must take the Dash action and move away from the phase monster by the safest available route on each of its turns unless there is nowhere to move. If the creature ends its turn in a location where it doesnt have line of sight to the phase monster the creature makes a Wisdom saving throw. On a successful save it is no longer frightened.
