Mistmaster

Mistmaster fighters use primordial energy to their advantage, channeling it through the form of powerful attacks propelled by the wind itself and misty clouds of fog to shield allies from certain death. 

Fog Of War

Beginning when you choose this archetype at 3rd level, you gain the ability to use an action to summon a cloud of fog. You create a 20-foot-radius sphere of fog centered on a point within range. The sphere spreads around corners, and its area is heavily obscured. When you use this ability you can see through the fog, as well as up to 4 other creatures of your choice. This fog can't be dispelled by any effect and lasts for an hour. You can have a number of fog clouds active at a time equal to one-fifth of your fighter level rounded down(minimum one). you can use this ability a number of times equal to your proficiency bonus, and regain all expended uses on a long rest.

Additionally at 5th level you can cast the misty step a number of times equal to your proficiency bonus or with any available spell slots, you also regain all expended uses upon a long rest.

Zephyr's Aim

Starting at 7th level, when you make an attack with a ranged weapon you can attack at long range without disadvantage. Additionally, you can use your reaction when a ranged weapon attack misses to redirect the projectile and give it a +5 attack roll bonus, potentially turning failure into a success. You can use this feature a number of times equal to your Dexterity modifier (minimum one) and regain all expended uses on a long rest.

Tempestuous Magic

Starting at 10th level, when you make a ranged weapon attack or a thrown weapon attack, you can choose to imbue the attack with the power of lightning. If the attack hits, the weapon transforms into a bolt of lightning that deals additional lightning damage equal to your fighter level. Additionally, any creature within 10 feet of the target must make a Dexterity saving throw or take half of the additional damage. You can use this feature only once per turn.

Wind Rider

Starting at 15th level, you gain the ability to soar through the air. You gain a flying speed equal to your walking speed.

Storm Mastery

At 18th level, you attain mastery in your abilities. You can cast  misty step at will and gain the ability to cast the storm sphere and  wind wall spells. You can cast either of these spells a number of times equal to your Dexterity modifier (minimum once) and regain all expended uses on a short rest. Additionally, you gain unlimited uses of your fog of war ability and can cast it on a creature to cause the cloud of fog to follow them.
