Dragoon Jump

You gain the ability to take a giant leap in the air and descend on your enemies.

If you have not taken any movement on your turn, as an action you can instantly vertically jump up to triple your jumping height and are suspended in air until the start of your next turn. At the start of your next turn, you can land anywhere up to your movement speed and gain the following benefits:

• You can make a melee attack on a single target, within 10ft of your landing point. Upon hit, roll one of your weapon’s damage dice one additional time +1 for every 10ft you descend on the target. 
• You have advantage on this attack roll if your enemy is on the ground and large or below in size. 
• You do not provoke opportunity attacks while taking this action and avoid all rough terrain between you and your landing point.

In order to complete this action:

• You must be able to jump unimpeded at least 10ft vertically
• You cannot be wearing armor heavier than medium 
• You must be proficient and wielding a weapon with the two handed and reach properties. 

If you are hit with an attack while suspended in mid air, roll a Dexterity or Strength saving throw. If passed you land at your intended target, if failed you immediately drop to your point of origin, taking 1 pt of damage for every 10ft you descend.
