Magical darkness envelops a 15-foot radius centered on your person and any light within 60 feet of you becomes dim light. All sources of non-magical light in this area are extinguished. Until the spell ends, you gain the following benefits:

• You gain immunity to necrotic damage and resistance to radiant damage.
• You can see in normal and magical darkness within 120 feet of you as if it were bright light.
• You can use your action to create a line of shadows 15 feet long and 5 feet wide. Each creature in the line must make a Constitution saving throw. On a failed save, a creature takes 14 (4d6) necrotic damage and you gain temporary hit points equal to the highest damage inflicted to any one target. On a success, the creature takes half as much damage and you do not gain any temporary hit points from that creature. This does not affect undead creatures or constructs.
