Burning Shield. When Jerry takes damage from a melee attack, he can use his reaction to create a temporary barrier of fire between him and his attacker. His AC against the triggering attack increases by 5, and he has resistance to damage dealt to him by the triggering attack if it hits, unless the damage is force or necrotic. The attacker also takes 18 (2d12 + 5) fire damage. Jerry must be able to see his attacker to use this reaction.

Jerry can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Jerry regains spent legendary actions at the start of its turn.

Searing Burst (Costs 2 Actions). Jerry emits magical, divine energy. Each creature of his choice in a 10-foot radius must make a DC 23 Dexterity saving throw, taking 28 (8d6) fire damage plus 14 (4d6) radiant damage on a failed save, or half as much damage on a successful one.

Enkindle. Jerry causes one creature he can see within range to ignite with intense flames, which last for 1d14 rounds. The creature takes 36 (4d12 + 10) fire damage immediately, as well as at the start of each of the creature's turns. Before taking this damage on its turn, the affected creature can use its reaction to attempt a Dexterity saving throw (DC 22) to extinguish the flames.

Fiery Movement. Jerry runs up to his walking speed, leaving a trail of fire wherever he goes. Any space he occupies during this movement ignites and remains on fire for 1 round or until it is extinguished by rain, a moderate or greater wind, or some similar effect. A creature that moves into this flaming area for the first time on its turn or starts its turn there must make a DC 22 Dexterity saving throw or take 36 (8d8) fire damage, or half as much on a successful save.
