Excal-heim
Burning Bloody Death. If the phoenix dies, it explodes.
Each creature in a 10-foot-radius must make a DC 20 Dex save, taking 10 necrotic damage on a failed save.
The fire ignites flammable objects in the area that aren't being worn or carried.
The explosion destroys the phoenix's body and leaves behind a 5 lbs egg.
The egg is immune to all damage, and after 1d6 days, it hatches a new Bloodflame phoenix.
Flyby. The Bloodflame phoenix doesn't provoke an opportunity attack when it flies out of an enemy's reach.
Illumination. The Bloodflame phoenix sheds bright light in a 15-foot radius and dim light for an additional 15 feet.
Fire Form. The Bloodflame phoenix can move through a space as narrow as 1 inch wide without squeezing.
Any creature that touches the phoenix or hits it with a melee attack while within 5 feet of it takes 1 fire damage.
With a touch, the Bloodflame phoenix can also ignite flammable objects that aren't worn or carried (no action required).
Bloodflame Touch. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 27 6d8 Necrotic damage. When dealing 48 damage, the target gains 1 level of exhaustion.
