Electrostaff of Unfettered Ferocity

All Vibroblades with the Baton sound type have the same sound, including the Electrostaff of Unfettered Ferocity. This isn't the official name, and this Vibroblade sound type may be labelled something like weaponmeleeelectrostaff01 in the background of the game.

I do not have a video of the Electrostaff of Unfettered Ferocity, but you can watch a video of the Battle Champion's Electrostaff weapon to hear the Baton sound type, which is the same as the Electrostaff of Unfettered Ferocity.

The Armstech crew skill trainer can teach players how to craft many crafted weapons sets as they level up in Armstech. However, these semi-retired crafted weapons sets are no longer available to be learned from the Armstech trainer from the launch of the game 1.0 - they were removed from the trainer in Update 4.0, and replaced with a more streamlined set of weapons schematics to be learned from the trainer. However, if you can find someone who learned the old schematics from the trainer pre-4.0, they can craft you these items, as the crafted items are Binds on Equip.
