This patch adds in four new souls for the Primalist, the normal mode for Tartaric Rifts, new raid rifts, new creatures, and the new Vostigar Peaks region. It also involves lots of balance changes, which the team has helpfully compiled for players to examine and offer feedback on. There’s not much time before the patch is supposed to hit the live servers, so you’d probably better get into the test client and start testing sooner rather than later if you want your feedback in the mix.
