Your eyes become an inky void imbued with fell power.

Each object in a 20-foot cube within range is outlined in light (your choice of color).

You conjure a phantasmal watchdog. Until the spell ends, the hound remains in the area unless you spend an action to dismiss it or you move more than 100 feet away from it.

Negative energy wracks the target and deals 7d8 + 30 necrotic damage.

A fiery mote streaks to a point within range and explodes in a burst of flame. The fire spreads around corners and ignites unattended flammable objects. Each creature in the area takes 6d6 fire damage.
