Darkfire

You summon a blaze of darkfire in your open hand. Darkfire emits no light, but produces the same heat as a regular fire, and it is invisible
except to those with darkvision. While you hold the dark flames, it doesn't harm you or your equipment, and you have several options, which can be taken immediately or performed as an action on a later turn:

Touch Make a melee spell attack against a creature within 5 feet of you. On a hit, the creature takes 3d10 Fire and 3d10 Necrotic
damage.

Hurl Make a ranged spell attack against a target you can see within 90 feet of you as you hurl the blaze of darkfire at them. On a hit, they take
3d10 Fire and 3d10 Necrotic damage.

Breathe You breathe in the darkfire, then exhale it in a 20-foot-cone in front of you. Creatures in the area must make a Dexterity saving throw. Creatures that fail the saving throw take 3d6 Fire and 3d6 Necrotic damage. If they succeed, they take half as much.

When you use one of these options, the darkfire is extinguished, and the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, increase the Fire and Necrotic damage by 1d10 per two
spell levels for the Touch and Hurl options, and by 1d6 per two spell levels for the Breathe option.
