Consecrate Weapon

The weapon you are holding is imbued with radiant power. For the duration, you can use your spellcasting ability instead of Strength for the attack and damage rolls of attacks using that weapon.

The weapon becomes magical, if it isn't already, and deals an extra 1d6 fire damage on each attack. Any target hit with the weapon Burns for 1d6 fire damage on each round following the attack. While the target is burning, attacks and checks against it have advantage as long as the attacker can see the target. The target cannot benefit from being invisible.

The target may put out the fire by succeeding a Constitution save equal to your spell save DC, or by being healed.

The spell ends if you cast it again or if you let go of the weapon.
