The nascent draconic soul of Archie, the Drakewarden.
Breath Weapon (Recharge 5-6).
When you command your drake to attack, it can now exhale a 15 cone of elemental energy in place of its Bite. Any creature in this cone must succeed a Dexterity saving throw against your spell save DC, or take 3d6 damage. On a successful save, a creature takes 1/2 damage. The damage type is determined by your drake's Draconic Essence.
