Staff, very rare (requires attunement by a wizard)
This staff of polished gray wood bears numerous runes carved along its length. The staff has 10 charges and regains expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff turns into dust and is destroyed.
While holding the staff, you can use an action to expend 2 or more of its charges to cast one of the following spells from it, using your spell save DC and spell attack bonus: Fortune's Favor (2 charges), Pulse Wave (3 charges), or Gravity Sinkhole (4 charges).
New Possibility. If you are holding the staff and fail a saving throw against a spell that targets only you, you can turn your failed save into a successful one. This property can't be used again until the next dawn.
