Chains of Elysium

Divine chains extend into the ground from the hands of the caster, emerging and ensnaring their foes from beneath like a marionette.

For the duration the caster’s speed becomes 0 ft. and they select any number of creatures within range. Each creature must succeed on a Strength saving throw or be restrained. A creature who is of evil alignment has disadvantage on this saving throw.

While restrained the creature takes an extra 1d8 radiant damage when hit by an attack. A creature may use its action to make a Strength (athletics) or Dexterity (acrobatics) check to free itself from the chains. 

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage dealt to restrained creatures increases by 1d8 for each slot level above 4th.
