Battle of Azeroth Patch 8.2 brings us the silent glider. The silent glider is similar to the Ankoan Wavetay and the Unshackled Waveray. If you want to get the silent glider, you must go to the coral forest of Nazjatar. As the name suggests, the forest consists of huge corals. So it's best to get a flying mount to make it easier to get to the corals. If you don't have a flying mount, you can do it also without one.
The corals have deep coral buds and these will give you a buff so you can jump further, and therefore come to other unreachable corals. Be prepared to spend a long time in the coral forest! You'll have to deal with a very rare enemy.
To be exact he only shows up every 1-8 hours. You're looking for "Silent", heard right, the name of your opponent and he'll drop the silent glider if you're lucky, but only with a very small chance. The silent glider has internal gases by nature and so it can survive in the depths and even fly through them. If you're one of the lucky few who have the privilege of owning the silent glider, you're really lucky.
You don't have to spend much time trying to get this mount, but get our boosting and get it immediately. Use it to fly through the air of BfA and glide through the depths of the oceans.
