Vandomar, Blue Arcanian

Frost Rime. Vandomar is not affected by difficult terrain created by ice or snow. In addition, the ground in a 10 ft radius around him is difficult terrain for creatures other than himself.

Spellcasting. Vandomar is a 6th-level spellcaster. His spellcasting ability is Intelligence (spell save DC 15, +7 to hit with spell attacks). He has the following spells prepared:
Cantrips (at will): frostbite, mage hand, ray of frost
1st level (4 slots): alarm, ice knife, shield, magic missile

2nd level (3 slots): hold person, shatter, snilloc's snowball swarm

3rd level (3 slots): counterspell, sleet storm, wall of water

Icy Blast. Vandomar can use his action to create a 15 ft cone of freezing wind extending from his outstretched hand. Each creature in the cone must make a Constitution saving throw. A creature takes 14(4d6) cold damage on a failed save, or half as much damage on a successful one. A creature that fails its save against this effect has its speed halved until the start of Vandomar's next turn

Wand of Winter. The wand has 7 charges, which are used to fuel the spells within it. With the wand in hand, you can use your action to cast one of the following spells from the wand, even if you are incapable of casting spells: ray of frost(no charges, or 1 charge to cast at 5th level; +5 to hit with ranged spell attack), sleet storm (3 charges; spell save DC 15), or ice storm(4 charges; spell save DC 15). No components are required.

The wand regains 1d6 + 1 expended charges each day at dawn. If you expend the wand’s last charge, roll a d20. On a 20, the wand melts away, forever destroyed.
