The newest version adds a ninth level for certain gear. The new level also requires new materials, not only in Rampaging RK-9 Kennel dungeons, but in the infamous RK-9 or in the hard mode with the common Corrupted Skynest dungeons. The patch further brings the latest battle pass, kicks off several events and made some fixed items and the Ninja class into one of the more popular ones. The patch notes show everything.
