The AetherWalker is a wand that requires level 70 to drop and originally only dropped during the season one for seasonal characters. After season one , it became available again at normal levels. There's more than just its rare property holding this weapon in power! The unique manipulation of Teleport has been replaced with an ability known as Arcane Power; giving you unlimited amounts if Pure Energy while also reducing your cool down time down from 5 seconds all together (to 0) simply by using them normally when equipped onto yourself or another person who owns their own set ( Teleport no longer has a cool down but costs 25 Arcane Power.) The patch 2.3 has introduced some interesting changes to the game that could potentially change how players play! The first of these is a way for you, as an classes with no resources whatsoever and limited abilities at their disposal; get rid of those pesky cool downs by using Teleport instead (all without spending any arcane power points or casting time on top). With Wormhole now available in combat (and free!), there's also another option when traveling across realms via portal devices like seen before...though this trip will cost just 0 cast-time but leave behind 1 second total post Activation.
This wand reduces the cooldown of Teleport to half of a second. Blizzard Community Manager Tyvalir explained the reason for this as follows:

"Virgil quickly lashed together remnants of his old broken wands and an unidentified artifact and sanctified them with his own blood, allowing him to teleport to safety and to begin formulating his revenge."
