Staff of the Four Seasons

Alter: This Magical Staff changes with the seasons. You can spend 10 minutes concentrating on the staff to change it to a different season. It remains in this new form for the next 8 hours before reverting to the current season again.

This staff can be wielded as a magic quarterstaff that grants a +2 bonus to attack and damage rolls made with it. In addition, your melee attacks deal an extra 1d8 cold (Winter), radiant (Spring), fire (Summer), or necrotic (Autumn) damage based on its season as long as there is at least 1 charge remaining on the staff.

This staff has 10 charges. While holding the staff, you can expend 1 or more charges to cast one of the following spells from it (depending on its season) using your spell attack modifier and spell save DC:

Winter: Color Spray (1 charge), Darkvision (2 charges), Sleet Storm (3 charges).
Spring: Guiding Bolt (1 charge), Moonbeam (2 charges), Plant Growth (3 charges).
Summer: Burning Hands (1 charge), Spike Growth (2 charges), Fireball (3 charges).
Autumn: Inflict Wounds (1 charge), Pass without Trace (2 charges), Vampiric Touch (3 charges)

The staff regains 1d6+2 charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff loses all foliage and vitality, becoming a gnarled, nonmagical quarterstaff.
