Julius’s vow of chains

5th Level Divine Conjuration (named)

Casting Time: 1 action

Range: 12 sqr. (18m)

Components: V, S, M (a blessed chain link)

Duration: 1 minute, concentration

Chains of radiant energy erupt from the ground, binding a fiend of your choice within range. The target must succeed on a Strength saving throw or become restrained. While restrained, the fiend has disadvantage on saving throws against divine source spells and cannot use reactions.

Each turn, the fiend can make a Strength saving throw to break free. On a failure, the chains tighten, dealing 3d8 radiant damage.
