That means, the loot you might have gotten as a drop would get replicated for your main character. If that isn’t interesting enough, the raid difficulty for DPS has been cut by half for all but the final boss. So if you, and your guild, have had trouble progressing in the raid. This is your chance to be able to go further in the raid, and get as many achievements as you can.
The reason Trion is doing this now is in order to help reduce the raid difficulty to entice more players to raid. Throw in the “Comet of Ahnket” Tier 3 raid that is coming later this month – the testing does come with its perks.
So what do you need to do to take advantage of this?
You need to use your character downloaded from Live to PTS. In order to download PTS, you need to select the region from the top right of Glyph. You need to send the Rift Team a message regarding the raid time and team members so they can watch you test the raid. You need to record your gameplay, so that the Rift Team can watch for bugs that may happen during the raid. It also is to verify that you have killed what you said you killed in the raid.
And that is about it. If you have already cleared part of the Mind of Madness raid, then make sure to send a message to the Rift Team member linked in step 2 above. That way they can try to duplicate your progress on the Public Test Shard. If you are planning on taking advantage of this chance, best of luck!
