Frostwave (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Range:||Self (10-foot circle or 15-foot cone)|
|Duration:||Concentration, up to 1 minute|
A spray of crystal laden cold sweeps out from you to deter movement. When casting this spell, you choose whether to affect a 10-foot circle centered on you or a 15-foot cone in front of you. For the duration, this ice turns the ground in the area into difficult terrain.
A creature of Medium size or smaller in the area when you cast the spell must succeed on a Strength saving throw or be restrained by the frost until the spell ends. A creature restrained by the frost can use its action to make a Strength check against your spell save DC. On a success, it frees itself. Prone creatures have disadvantage on the save and the check.
When the spell ends, the frost dissipates harmlessly.
