Windmaker

A dark green blade meets the black handguard and hilt. A refined orb of the Wind Ore makes up the pommel and it glistens in the light.
The Windmaker is a versatile weapon in terms of the reach it provides. It may be handled as a traditional blade that allows for the user to strike targets within 5 feet of it for 2d6 slashing damage. However, it may also be handled much like a spear or halberd to pierce the enemy. When handled in this manner, the Windmaker has 10 feet of range and does 1d10 piercing damage. Windmaker grants you a +3 to attacks roll made with the weapon.
Wind Slash. As a bonus action, you unleash a piercing or slashing wind in a 30 foot line. You must make an attack roll against each enemy in the line and you are teleported to the end of the line. You may use this feature a number of times equal to your proficiency bonus. The uses replenish on a long rest. 
Gale Blast. As a reaction to being targeted by a melee attack, you send out a blast of gale force winds in a 20 foot radius. Each target within range must make a DC 20 Strength saving throw and be pushed back 20 feet and knocked prone on a failure. On a success, the creature is pushed 10 feet back and is not knocked prone. You may use this feature a number of times equal to your proficiency bonus. The uses replenish on a long rest.
Wind Scythe. Windmaker slashes the air itself and unleashes a slashing arc of wind in A 30 foot cone.  Each target in range must succeed on a DC 20 Dexterity saving throw or take 16 (3d10) slashing damage. On a success, a creature takes half damage. This attack may be used in place of one of your weapon attacks. You may use this feature a number of times equal to your proficiency bonus. The uses replenish on a long rest.
