Посох мороза

You have resistance to cold damage while you hold this staff. The staff has 10 charges. While holding it, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC: **_cone of cold_** (5 charges), **_fog cloud_** (1 charge), **_ice storm_** (4 charges), or **_wall of ice_** (4 charges). The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff turns to water and is destroyed.
