Diatium Onslaught

Diatium Onslaught Armor Set

The Diatium Onslaught armor set is a crafted armor set that Armormechs can craft at armormech level 380 if they have found the schematic in Star Wars: The Old Republic. This set is wearable only by Republic characters, who are level 47 or higher on any Republic class in the Outfitter tab but is restricted to characters that can wear heavy armor in the normal equipment slots.

Crafting the Diatium Onslaught Armor Set as an Armormech

Armormechs can craft the Diatium Onslaught armor set at armormech level 380 or higher. To craft this set, Armormechs must first find the schematic which can be found in the world and through crew skill missions at random. The easiest way to get this schematic is to buy it from another player on the GTN. This schematic is not always available on the GTN, so players should continue checking the GTN over time to see if it becomes available.

Buying the Diatium Onslaught Armor Set from the GTN with Credits

Pieces of the Diatium Onslaught set can be found on the GTN, which is an auction house where players can buy and sell unbound items. To find the GTN at level 10 or higher, look for the Galactic Trade Network section of the Republic or Imperial Fleet.

It can sometimes be difficult to find specific pieces on the GTN, especially because this armor set can only be crafted by Armormechs who have found the schematic. If you don't see the pieces you want listed, you can look for other pieces of the set and try mailing the player who crafted it to trade with them, as some crafters try and collect all the schematics in the game and might have the pieces you are looking for.

Trading for the Diatium Onslaught Armor Set with Another Player

Other players who are Armormechs may have Diatium Onslaught pieces they are trying to sell that they have crafted - or may be willing to craft the set for you if they have the schematics. You can post in the /trade chat ingame to ask if anyone is selling the set, ingame mail an armormech you find on the GTN selling other pieces, post on the official forums for your server, post on the /r/swtor_trade subreddit, or post in the #trading-terminal channel of the SWTOR Discord Chat.


This armor set changes appearance when it is transferred Imperial-side. It keeps the same name, but will take the appearance of a set for the mirror-class of this set.
