This wand is specifically attuned to work abjurationist spells.

While wielding this wand, whenever you cast an abjuration spell, you may expend a number of charges equal to the spell level cast, and not expend a spell slot.  The spell must be cast the minimum level possible and you must have an available spell slot of that level to cast it.

This wand has 3 charges and regains 1d3 charges at dawn. When the wand reaches 0 charges roll a d20, on a 1 the wand loses all its abilities and becomes a non-magical wand.
