Arcane flare

A crossbow, light, crossbow, hand, or Quarterstaff you are holding is imbued with arcane power. For the duration, you can use your spellcasting ability instead of Strength/dexterity for the attack and damage rolls of attacks using that weapon, and the weapon’s damage die becomes a d8 and it's attack range increases by 15 ft. If the attack deals damage, it can be the weapon’s normal damage type, or you may roll a d4 to determine the magical damage type. Attacks made this way are considered Ranged weapon attacks (Not melee and not spell).

D4:
1 - Fire
2 - Cold
3 - Lightning
4 - Force

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

Cantrip Upgrade. The damage dice roll and attack range are modified when you reach levels 5 (1d10, +30ft), 11 (1d12, +45ft), and 17 (2d6, +60ft).
