question about obsidian armor

Can someone explain to me how obsidian armor works? I know that there are 6 types of obsidian armor (example, monks: they have Ascetic's, Acolyte's, Shepherd's, Judge's, Disciple's, and Wanderer's). Do they all turn out to look like the monk obsidian armor? and can someone please tell me the materials needed to make them. Thanks in advance.

Here's the link to wiki :

There's pic for all of the Obsidian aka FOW armor sets available, also there's a list of all the materials need to craft them. And yeah different armor name, have the same look but different bonus on them. But since all armor set had been upgrade to take insignia now, there won't be any different anymore.

Now that all armour uses Insignias, go by the materials needed for the Insignia version.

for each profession, there is a different art style. Each profession has one art style for fow armor, regardless of mods on the armor

and as Curse You stated, all are insignia based now. any obsidian armor you saw for a profession all looked the same just like how sunspear armor with different insignias would look the same.
