Crimson Chains Of Carceri

You summon red chains of arcane energy to bind an opponent within range. The target must make a Strength saving throw. On a success, the spell does not take effect. On a failure, the target is considered restrained. At the start of each of the target's turns, for as long as you maintain concentration on this spell; the target makes a strength saving throw. On a success, the target breaks free of the bands and the spell ends. On a failure, the chains blast with arcane force and the target takes 2d6 Force damage.

At Higher Levels: When you cast this spell with a Spell slot of 4th level or higher, you can target 1 additional creature with the spell, but the additional target must be within 30 feet of the previous target.
