Tier 17 map

The most difficult and most rewarding content in Path of Exile can be found in Uber Pinnacle bosses, such as The Maven and The Searing Exarch. Currently the only way to access these bosses is by allocating specific Keystones on the Atlas Passive Tree. While this system offers a nice element of control, it causes a problem: Rewards and access to the non-Uber variants are now economically priced around the rewards of the Uber fights. This means it is wasteful to run the non-Uber variants instead of simply selling them.

In addition, the difficulty jump between the Pinnacle and Uber Pinnacle content was relatively large, and there wasn't obvious content available that could bridge this gap. Many players would give up on their character before being able to defeat the Uber Pinnacle Bosses.

Tier 17 Maps have 20% Quality and are Unmodifiable. Test your characters in new ways. These feature a new set of Bosses, Uber Monsters, and a new tier of modifiers that can roll on Maps.

Rewards

These fragments can be obtained from the new Tier 17 Maps we're also introducing with this patch. These Maps give you access to the Uber Pinnacle content.

There are five new Tier 17 Maps in total. For each of their bosses, an existing unique item has been removed from the core drop pool, and now exclusively has a chance to drop from these bosses. These unique items have been rebalanced to be fitting rewards for the content

• Fortress Map - Yoke of Suffering
• Citadel Map - Manastorm
• Sanctuary Map - The Dark Seer
• Ziggurat Map - Wraithlord
• Abomination Map - Malachai's Mark

The fifth slot in the Map Device is now unlocked upon completing a non-Valdo's Tier 17 Map.

Acquisition

Voidstones, when socketed into the Atlas of Worlds, have a chance to convert Tier 16 maps into a random Tier 17 map.

With average map investment, a player can expect to see a Tier 17 map drop roughly once every 5 maps. To prevent a massive disparity of Tier 17 maps drops with certain "juicing" strategies, Tier 17 map drops are subject to "diminishing returns" within a map; this means that the first Tier 17 map dropped in a map will use the above conversion rate, then diminish to a unannounced point for subsequent drops in the same map.

Tier 17 maps cannot drop inside a Tier 17 map.
