Chains of the Guilty (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Duration:||Concentration, up to 1 minute|
Ethereal black chains appear from the ground in a 20-foot square starting from a point within range. For the duration, these chains turn the ground in the area into difficult terrain. A creature in the area when you cast the spell must succeed on a Strength saving throw or be restrained by the chains until the spell ends. A creature restrained by the chains can use its action to make a Strength check against your spell save DC. On a success, it frees itself.
When the spell ends, the chains turn to ash and are blown away.
