The centerpiece of the patch is the new talisman challenge league. In this game mode, players will encounter special mobs that possess talismans (super-charged amulets) that are apparently quite desirable. The league also contains challenges and special locales that require talismans to conquer.
The patch is bringing out several additional skills, new support gems, more unique items, the ability to bring out two pets at once, and so, so much more. It also marks the official launch of Path of Exile in Brazil with full support for Brazilian Portuguese. The devs have a preview of the patch notes up for anyone wanting to dive in to all of the juicy details.
