Where can I learn "Ruusan Relic of Devastating Vengeance"? It's not on trainer or can't be learned from any of my schematics. I know it's out there somewhere because they are on GTN.

they were at the trainer back in 3.0..they should still be available researching starting from the green version at your trainer.. green is 168 rating.

As of 4.0 all schematics learned from trainers start at blue quality, so there are no longer any 168 rated relics available from the trainers. The highest rated relic schematics you can learn from the trainer are for 178 Hiridiu relics, which can then be REd to learn the schematic for relics with a 186 rating. The Ruusan relics were replaced by these and relegated to the archives section of any artificer who learned them prior to 4.0, so they can still be crafted, but only by someone who already learned them.

186 is obsolete. How about the rest ?

I assume only the ops ones are REable since the ones that I get via crystals are not ?

186 may be "obsolete", but since the only way to get a >186 proc relic is to get lucky an an ops drop/RE an ops drop, they're still popular.

You can easily get any of the Proc Relics in 204 and 208 rating. The PvP ones.

 

Getting 204's is very easy indeed, just a few WZ's, not even a weekly will get you a pair.

 

Hope that helps
