Deaths Domain

The Ground around you in a 20-foot radius becomes shrouded in necrotic energy. If a creature within the radius casts a necromancy spell they gain 5 temporary hitpoints. When the spell is initially cast the caster chooses one more effect in the radius and can change it with a bonus action.

- The Energy thickens and obscures visibility in the area for those that can't see in magical darkness

-Skeletal hands of necrotic energy burst from the ground and turn the area into difficult terrain

-Allies within the area count as undead and gain resistance to Necrotic damage

For every level above 3rd level that the spell is cast increase the radius by 10ft
