Scale of Kethelrax
Weapon (Dagger), Uncommon (Requires Attunement)

This Dagger is said to have been created by Kethelrax the Cunning, the kobold warlord of Shaarat Kol. Its short, crimson blade resembles a red dragon’s scale, and tiny flames dance along its edge.

While you are holding this Dagger, you can use it as a Spellcasting Focus for your spells. Additionally, you can cast Fire Bolt as a Magic action, using Intelligence, Wisdom, or Charisma (you choose when you Attune to the dagger) as the spellcasting ability.

Whenever you hit with a weapon attack using this Dagger, you can choose to deal Fire damage instead of Piercing damage.
