Don't put points into its movement speed if you want to glide faster. It glides as fast you run, so putting points into your movement speed will increase how fast it will glide. Hope this saves you from wasting levels like me : )
Amazing for riding Ptera. Right before you run out of stamina on ptera, simply jump off while holding one of these and the ptera will regain its stamina in the air. Once your pteras stamina is full you can hop back on. Never need to land in dangerous areas again.
Some youtubers say that they are useless. WRONG. They are better than wasting time crafting a parachute and they can attack and they are small so very hard to target. I saw one of these drill through a rex and the thing didn’t even take damage once and the rex died.
