Legendary Resistance (3/Day). If the Eriflamme fails a saving throw, it can choose to succeed instead.
Magic Resistance. The Eriflamme has advantage on saving throws against spells and other magical effects.
Multiattack. The Eriflamme makes four Claw attacks. It can replace one of the attacks with a Bite attack.
Claw. Melee Weapon Attack: +18 to hit, reach 15 ft., one target. Hit: 20 (3d6 + 10) slashing damage plus 7 (2d6) fire damage.
Bite. Melee Weapon Attack: +18 to hit, reach 10 ft., one target. Hit: 24 (4d6 + 10) piercing damage plus 33 (6d10) fire damage.
Reform. All the Eriflamme's fire elementals vanish and the Eriflamme reappears in one of their spaces. The Eriflamme's hit points are equivalent to the combined hit points of the fire elementals.
Split (2/Day). As a reaction to taking damage, the Eriflamme can split into fire elementals and reduce the damage to 0. The Eriflamme can form up to 10 fire elementals, splitting its remaining hit points between them. The fire elementals appear in spaces adjacent to or within the Eriflamme's old location, and all act on the Eriflamme's initiative. They gain a +5 bonus to attack rolls and have the Eriflamme's Reform action.
Slam. The Eriflamme makes a Claw attack, which deals force damage instead of slashing damage if it hits.
Fireglide. The Eriflamme moves up to half its speed. It can fly during this movement.
Chomp (Costs 2 Actions). The Eriflamme makes a Bite attack with advantage.
