Cometfall

7th-level evocation

Casting Time: 1 Action

Range: Touch

Components: V, S, M* (a gold piece equivalent to the object’s worth, which is consumed)

Duration: 10 Minutes

An icy ball of magic forms above you, expanding into a 5-foot radius comet, which you then send at a point you can see within range. Upon impact on the ground or against something solid, the comet detonates in an icy explosion. Any creature that was within a 30-foot radius of the center of this comet must make a Dexterity saving throw.

A creature who was under the 5-foot radius comet who fails takes 12d8 cold damage, or half on a success. A creature who was not under the 10-foot radius comet but was within the 30-foot radius explosion takes 6d8 cold damage on a failure, and half on a success.

Any creature who takes damage this way has their movement speed halved until the end of their next turn.

At Higher Levels. When you cast this spell at 8th level or higher, the damage increases by 1d8 per spell slot.
