Arcane Lockpick

This tiny pick of mithril has intricate elven runes inland with diamond dust. 

The pick has 6 charges, and regains 1d4+1 charges after a long rest.

When used to pick a mundane lock, you gain advantage on the roll. If the roll results in a failure a charge is expended.

The pick grants the ability to remove the Arcane Lock spell. The roll to pick an arcane lock is an Intelligence (Arcana) roll. The DC is equal to the spell save DC of the caster of the lock. Failure on the roll causes 2 charges to be expended on the pick.

If the pick is ever reduced to 0 charges, it breaks.
