Bladesinger’s Spear

Weapon (spear), very rare (requires attunement)

You have a +1 bonus to attack and damage rolls made with this magic spear, which has the finesse property. The spear returns to your hand immediately after it is used to make a ranged weapon attack. You gain the following benefits while holding the spear:

• You can use the spear as a spellcasting focus for your wizard spells.
• When you hit with an attack roll using the spear, you can unprepare one wizard spell you have prepared to deal extra force damage equal to 1d8 + the spell’s level to the target.

When you unprepare a spell using this spear, you can’t cast that spell again until you have finished a long rest and spent the requisite time preparing it again.
