Whenever you cast a spell through this wand, you ignore half cover, gaind +2 spell attack, and raise your spell DC by 2. 

This wand has 12 charges. When casting a spell, you can expend charges to raise the level of the spell, however you can not exceed your own highest spell slot. Each raise costs a number of charges equal to cumulative levels between the expended spell slot and the final level. (Using a 2nd level spell slot to cast a 4th level spell this way would expend 7 charges).

Whenever you cast a spell using this wand, make an arcana check against DC "15 + final spell slot level + expended charges", if you fail this check roll for an effect on the wild magic table.
