You sap the vitality of one creature you can see in range. The target must succeed on a Constitution saving throw or take 1d4 necrotic damage and fall prone.
This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
You touch one willing creature. While this spell is active, the target's senses are heightened. If the target rolls a 9 or below on the die when making a Wisdom (Perception) check, they instead act as if they rolled a 10.
You spread your arms wide, allowing yourself to become enveloped by the air around you. Until the end of your next turn, any ranged attack against you is made with disadvantage.
Melee attackers who successfully hit you must make a Constitution saving throw against your spell save DC. On a failure, the attacker is flung away from you up to 10 feet and is knocked prone.
