While attuned to this staff, you may treat it as your spellcasting focus.

This staff has 7 charges, and it regains 1d4 + 1 at dawn each day. Whenever you cast a spell of 1st or 2nd level that requires concentration for no longer than a minute, you may expend one of the charges on this staff to cast it again. While concentrating on both spells, if you would lose concentration, you lose concentration on both spells.

Notes: Requires attunement by a Sorceror, Warlock, or Wizard, Control
