Very Rare Wondrous Item, Requires Attunement

• Breath of the Furnace can only be used when wielded in two hands
• Can be used as a spellcasting focus for Cleric Spells

Cremation. As an action, you can use the Breath of the Furnace to create a jet of holy fire, forcing a creature that you can see within 30 feet of you to make a DC 16 Dexterity saving throw, making them take 2d10 Fire plus 2d10 Radiant damage on a failure. 

• (Recharge 6) While this item is charged, you can cause this ability to affect all creatures in a 30-foot cone instead and make it deal half damage on a successful saving throw as well.
  • Bringing an Undead creature to 0 Hit Points with Cremation automatically recharges this feature. 

Blessed Ashes. When you deal Fire or Radiant damage to a non-tiny corpse or creature at 0 Hit Points, or when you bring a non-tiny creature to 0 Hit Points with Fire or Radiant damage, the creature is disintegrated and you can immediately cast Bless (1st level) as a reaction using the item without expending a spell slot. 

• If you disintegrate more than one corpse or creature with a single effect, the Bless spell functions as if it was cast with a spell slot of level equal to the amount of disintegrated creatures.
  • If you disintegrate a creature of CR 10 or higher, the Bless spell doesn’t require concentration. 

Deus in Igne. You automatically succeed on Concentration checks caused by Fire or Radiant damage.
