Tusksong's Abjurer's Blade

You weave together threads of your arcane ward to create a sword of solidified arcane light, with an orb containing an unknown necrotic substance (on the pommel) in your hand. This magic sword lasts until the spell ends. It counts as a simple melee weapon with which you are proficient. It deals 2d8 force damage on a hit and has the finesse, light, and thrown properties (range 20/60) using your Intelligence Modifier for attack and damage roles. In addition, when you use the Abjurer's Blade to attack after a successful Counterspell, you have advantage on the attack role.

If you drop the weapon or throw it, it dissipates at the end of the turn. Thereafter, while the spell persists, you can use a bonus action to cause the sword to reappear in your hand.

Per every point of damage dealt by your Abjurer's Blade, one quarter of this damage rounded down is reduced from your Arcane Ward. If your Arcane Ward is reduced to 0, the blade vanishes from your hand until your arcane ward is replenished at minimum one quarter of your Arcane Ward maximum.

At Higher Levels. When you cast this spell using a 3rd- or 4th-level spell slot, the damage increases to 3d8. When you cast it using a 5th- or 6th-level spell slot, the damage increases to 4d8. When you cast it using a spell slot of 7th level or higher, the damage increases to 5d8.
