How To Use Arcane Weapon in 5e

Arcane Weapon can be cast as a bonus action on any weapon that you are currently holding. When you cast it, select from one of several damage types outlined in the spell’s description. On every attack you make with this weapon you deal an extra 1d6 of the chosen damage type. Additionally, this weapon is now considered magical for the spell’s duration. On any following turn, you can use a bonus action to change the damage type.

Arcane Weapon is a concentration spell, which means that if you take damage, you must succeed on a Constitution saving throw or you will lose concentration. In this case, the spell ceases to function and must be recast. Further, you can only have one active concentration spell at a time.

Similar Spells

Since Arcane Weapon is not officially published anywhere, some DMs may not allow it. If you want to get similar results, there are a few other options available.

Arcane Weapon Vs Elemental Weapon 5e

Elemental Weapon was introduced in the Player’s Handbook and has been in D&D 5e since the very beginning. It shares a lot in common with Arcane Weapon, but with two important differences. Arcane Weapon gives no bonus to attack and an extra 1d6 damage die on each attack. Elemental Weapon gives a +1 to attack and an extra 1d4 damage. You’ll hit more often, but not as hard.
Also, Elemental Weapon is a 3rd-level spell, meaning it isn’t available until much later in the game. Additionally, Elemental Weapon requires a full action to cast and the damage type cannot be changed.

Arcane Weapon Vs Arcane Infusion

If you’re playing as an Artificer, you have the option at level 1 to create up to two Arcane Infusions at a time. If you choose to create an infused weapon, it receives +1 to Attack and Damage rolls, but no elemental bonus.
