While browsing youtube for the minimal content there is on the game, after been gone off the game for years (casual player) I found this video for a warrior build with Eternal Aether Spark. However i can not find this weapon anywhere in the codex? Did it get removed, renamed or am i just missing something?
Thanx in advance!
Aether Spark is a Wizard item. Use a Jasper crystal to change it to Warrior. 
Welcome to the forums!
Welcome to DQ Forums @PurpleHaze !
whenever you find an Item in a build that isn’t in a Classes list in the Codex, just check the other 2 Classes (Jasper Crystal can be used to change an Items Class).
also, some Items that are in 2 or 3 of the Classes might have one or more affixes that are different between the Classes.
