Exceptional Weapon

You touch a melee weapon and imbue it with magic.

While the spell lasts:

• As a Bonus Action, you can cause the weapon to appear in a free hand.
• You can cause the weapon to disappear without requiring an action. The weapon is stored in an extradimensional space.
• If the weapon is not magical, it becomes magical for the duration of the spell.

You can only have one exceptional weapon at a time

In addition, whenever you make an attack with the weapon, you can replace that attack with an Arcane Slash.

Arcane Slash. 60 ft.

• Attack: Choose a creature you can see within range. Make a weapon attack against the target using the weapon.
• Hit: The target takes the same damage and effects as if it had been hit by a normal attack made with the weapon.
• Before making the attack roll, you can change all of the attack's damage to Force, Acid, Cold, Fire, Lightning, or Thunder.
• Attacks made with Arcane Slash ignore Half Cover.

Permanent Bond. When you cast this spell, you can cause the weapon to require Attunement from the caster and occupy one of their Attunement slots. If you do, the duration becomes Until dispelled. The spell ends if the Attunement ends or if the effect is dispelled.
