Fire Bolt (Cantrip). Ranged Spell Attack: +6 to hit, range 120 ft., one target. Hit: 11 (2d10) fire damage.

Staff of Frost. While holding this staff, Avarice can expend 1 or more of its charges to cast one of the following spells from it (spell save DC 14): cone of cold (5 charges), fog cloud (1 charge), ice storm (4 charges), or wall of ice (4 charges). The staff regains 1d6 + 4 charges daily at dawn. If its last charge is expended, roll a d20; on a 1, the staff turns to water and is destroyed.

Banishing Rebuke (Recharges after a Long Rest). When Avarice is damaged by a creature that she can see within 60 feet of her, she can banish that creature to a frigid extradimensional prison for 1 minute. While there, the creature is incapacitated and takes 5 (1d10) cold damage at the start of each of its turns. At the end of each of its turns, the creature can make a DC 14 Charisma saving throw, escaping the prison on a success and reappearing in the space it left or in the nearest unoccupied space if that space is occupied. A creature that dies in the prison is trapped there indefinitely.
