Special Equipment. Ringlerun wields a staff of power. It has 20 charges when fully charged and regains 2d8 + 4 expended charges daily at dawn. If its last charge is expended, roll a d20. On a 1, the staff retains its +2 bonus to attack and damage rolls but loses its other properties; on a 20, it regains 1d8 + 2 charges.

Spellcasting. Ringlerun casts one of the following spells, using Intelligence as the spellcasting ability (spell save DC 14):

At will: light, mage hand, prestidigitation

1/day each: banishment, dispel magic, fly, knock

3/day each: charm person, detect magic, sleep
