Death March

You empower yourself and nearby allies with shadow magic, with the life-draining force of death. A 30-foot radius of effect moves with you, centered on you, for the duration of the spell. You and every friendly creature within this radius gains the following benefits while it remains within the radius:

• Deals an extra 1d6 necrotic damage on a hit with any weapon attack (or 1d8 if you have the Necrotic Power feature).
• Has resistance to necrotic damage and poison damage.

At Higher Levels. When you cast this spell using a spell slot of 5th level, the extra damage increases to 2d6 (or 2d8 if you have the Necrotic Power feature).
