Gust of wind

Gust of wind is an evocation spell that blows away or knocks down smaller creatures.

Effect
This spell creates a strong blast of air that originates from you and moves in the direction you are facing. The force of this gust automatically extinguishes candles, torches, and similar unprotected flames. It causes protected flames, such as those of lanterns, to dance wildly and has a 50% chance to extinguish these lights. Creatures caught in the area may be affected (see the Dungeon Master's Guide for details about wind effects on creatures). Any creature is entitled to a saving throw to ignore the gust's effects.

A gust of wind can do anything a sudden blast of wind would be expected to do. It can create a stinging spray of sand or dust, fan a large fire, overturn delicate awnings or hangings, heel over a small boat, and blow gases or vapors to the edge of the range.

Focus
A tiny leather bellows.
