Ringlerun

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.

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

At will: light, mage hand, prestidigitation

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

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

Ringlerun makes three staff of power or Freezing Ray attacks. He can replace one of those attacks with a use of Spellcasting.

Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) bludgeoning damage, or 5 (1d8 + 1) bludgeoning damage when used with two hands, and Ringlerun can expend 1 of the staff's charges to deal an extra 3 (1d6) force damage.

Ranged Spell Attack: +8 to hit, range 120 ft., one creature. Hit: 27 (6d8) cold damage.

While holding his staff of power, Ringlerun can expend 1 or more of its charges to cast one of the following spells from it (spell save DC 14, +8 to hit with spell attacks): cone of cold (8d8 cold damage; 5 charges), fireball (10d6 fire damage; 5 charges), globe of invulnerability (6 charges), hold monster (5 charges), levitate (2 charges), lightning bolt (10d6 lightning damage; 5 charges), magic missile (1 charge), ray of enfeeblement (1 charge), or wall of force (5 charges).
