Wind's Favor

You create a localized area of strong wind (approximately 30 mph). This effect has limited utility in battle (see Table 3—24: Wind Effects, page 95 of the Dungeon Master's Guide), but is often used to propel sailing craft. By concentrating as a full-round action, you can change the direction of the wind by 45 degrees.   This spell is effectively identical to the spell-like ability that can be gained by a character with the lesser Mark of Storm (see page 66 of the EBERRON Campaign Setting), except the range and the affected area are different, as given above.
 

You create a steady, directional wind in a 10-foot-wide, 10-foot-high, and 120-foot-long line originating from a point within range. The wind blows at approximately 30 miles per hour (strong wind) in a direction you choose.   The wind has the following effects within its area:   Propels sailing vessels or airships effectively, as a favorable tailwind.   Extinguishes unprotected flames, disperses vapors, gases, and smoke within the area in 1 round.   Ranged weapon attacks made through the wind suffer disadvantage unless fired in the same direction as the wind’s flow.   Tiny or smaller flying creatures must succeed on a Strength saving throw against your spell save DC or be pushed 10 feet in the wind’s direction at the start of their turn.   As a bonus action, you can adjust the wind’s direction by up to 45 degrees.   At Higher Levels. When you cast this spell using a higher level spell slot, increase the length of the wind's area by 30 feet for each slot level above its base level.
