Alethra's Gale

You trace a sigil in the air and two gusts of wind burst out, shredding everything they hit. Make a ranged spell attack against a target within range for each gust. You can direct the gusts at the same target or at different ones. On a hit, the target takes 2 slashing damage.

This spell creates two additional gusts of wind at 5th level (4), 11th level (6), and 17th level (8).
