4th-level Spell: Shackle of Flame

Whispering (Conjuration)

You summon a ring of fire, which snaps shut on the target’s limb and attempts to pin it in place. The target must make a Dexterity saving throw. On a failure, it is shackled. While shackled, the target takes 6d6 fire damage at the start of each of its turns. The first time it attempts to move on its turn, it must make a Strength saving throw. On a failure, it takes 4d6 additional damage and its speed is reduced to 0 until the start of its next turn. On a success, the spell ends.

• At Higher Levels. When you cast this spell with a spell slot of 6th level or higher, both instances of damage are increased by 1d6 for every two slot levels above 4th.
