Keen Smell. Zephyros has advantage on Wisdom (Perception) checks that rely on smell.
Fling. Zephyros tries to throw a Small or Medium creature within 10 feet of it. The target must succeed on a DC 20 Dexterity saving throw or be hurled up to 60 feet horizontally in a direction of Zephyros's choice and land prone, taking 1d8 bludgeoning damage for every 10 feet it was thrown.
Wind Aura. A magical aura of wind surrounds Zephyros. The aura is a 10-foot-radius sphere that lasts as long as he maintains concentration on it (as if concentrating on a spell). While the aura is in effect, Zephyros gains a +2 bonus to his AC against ranged weapon attacks, and all open flames within the aura are extinguished unless they are magical.
Multiattack. Zephyros makes two staff attacks.
Staff of the Magi. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 20 (3d6 + 10) bludgeoning damage, or 23 (3d8 + 10) bludgeoning damage if used with two hands. This damage is considered magical..
Rock. Ranged Weapon Attack: +12 to hit, range 60/240 ft., one target. Hit: 30 (4d10 + 8) bludgeoning damage.
