Fey Ancestry. Zaek has advantage on saving throws against being charmed, and magic can't put him to sleep.

Spellcasting. Zaek is a 3rd-level spellcaster. He can cast the following spells from the wizard spell list. Intelligence is his spellcasting ability for these spells (+3 to hit, spell save DC 11):

Cantrips (at will): dancing lights, fire bolt, mage hand

1st level (4 slots): burning hands, magic missile, shield

2nd level (2 slots): darkness

Sculpt Spells. When Zaek casts an evocation spell that affects other creatures that he can see, he can choose a number of them equal to 1 + the spell’s level. The chosen creatures automatically succeed on their saving throws against the spell, and they take no damage if they would normally take half damage on a successful save.

Staff. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 3 (1d6) bludgeoning damage, or 4 (1d8) bludgeoning damage if used with two hands.
