Mika The Gale

This wooden blade, magically reinforced, strikes as a shortsword or rapier, dealing Force damage. Once per day, on a successful hit, creatures in a 15 ft cone ahead of strike must make a DC 14 Strength save. On a fail, they take 1d10+3 Thunder damage and are pushed 15ft back in direction of attack; on a crit, they are also deafened. On success they take half damage and remain in position. At level 5 feature increases to twice a day.
