Blightward

You create a barrier of protective energy around a point you choose within range. The area forms a 20-foot radius sphere that prevents Blighted creatures from entering or remaining within it. Blighted energy attacks can pass through the barrier, but creatures inside the barrier have resistance to Blighted energy damage.

• Any Blighted creature that starts its turn in the area must make a Constitution saving throw (DC 15).
  • On a failed save, the creature takes 4d6 radiant damage.
  • On a successful save, the creature takes half damage but still cannot enter the sphere.
• Blighted creatures are repelled from the area and cannot cross into it for the duration of the spell.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher:

• The radius increases by 5 feet for each slot level above 3rd.
• The caster must sacrifice an additional 5 HP for each slot level above 3rd.
