Frost Glider(New Mob For Mountains!)

FROST GLIDER-MOB-This mini-boss would spawn in ruins generated at the highest snowcapped peaks. They would be neutral but territorial to all hostile mobs and players, meaning players who wish to build their bases on their territory must first defeat them. When they choose to approach someone at a lower altitude than they, or are pushed off a cliff, they will spread their arms, exposing a membrane connected from the arm to the hip, and slowly descend to the ground. Their membrane are tough as well, deflecting arrows when shot. When engaging a player, occasionally they will raise their arms, and using the membrane under their arm, will attempt to push players away with a icy gust of wind by flapping their arms. The gust of wind will carry entities and mobs backwards for a short distance. This way, players have the additional worry of getting pushed off a cliff as well as surviving the attacks of the Frost Glider. When slain, Frost Gliders will drop a FROST GLIDER MEMBRANE. 

FROST GLIDER MEMBRANE-ITEM-Dropped by the Frost Glider, they can be combined with an Elytra in a smithing table to add a low amount armor points and durability to the Elytra, with the added effect of deflecting arrows and other projectiles when hit in the back, similar to the shield. When brewed, they will give the player the “Gust” effect, which makes it that every time the player lands from flying an Elytra, they will create a gust of wind in the direction they landed.
