After the fifth phase of the TBC Nostalgia Suit is opened, the S4 Guardian Series equipment will meet the player.
If you're still brushing ZAAM's Natural Mercy Brooch right now, you can brush the Honor and wait for the next stage to buy a suppression pendant. The S4 Necklace requires 15300 Honor points and 5 Storm Tags, and when inserted with 10 Rush Gems, the properties are stronger than the Natural Mercy Brooch.
