In addition, your spell attack roll is made at advantage, saves against the spell are made at disadvantage, and the spell deals maximum damage.

Absorb Spell While holding this wand, you can expend 7 charges and use your reaction to cast the counterspell spell as a 4th level spell from it. If you successfully counter the spell, the wand absorbs the spell's energies and stores it until you use it.

The wand can only store one spell at a time.

While this wand has a spell stored in it, you can cast that spell. The spell uses the slot level, spell save DC, spell attack bonus, and spellcasting ability of the original caster, but is otherwise treated as if you cast the spell. The spell cast from the wand is no longer stored in it, freeing up space.

As a bonus action you can harmlessly discharge the spell stored in the wand without casting it, freeing up space.
