This staff of polished gray wood bears numerous runes carved along its length. The staff has 10 charges and regains 1d6 + 4 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).
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.
This weapon can be used with one or two hands. A damage value in parentheses appears with the property—the damage when the weapon is used with two hands to make a melee attack.
