PoE Tier 17 Maps Crafting Currency – Path of Exile

Tier 17 Maps are now modifiable only with Chaos Orbs, Vaal Orbs, and Chisels (previously only Chaos Orbs). They also now drop with a random Quality, rather than always dropping with 20% Quality.

fter socketing your first Voidstone on the Atlas, you can now hover over Tier 14 and higher Maps and view what Tier 17 Map can be dropped there.
Monsters in Tier 17 Maps now have less Life and deal less Damage, now fitting better into the progression between Pinnacle and Uber Pinnacle content.
The Union of Souls Map Modifier can no longer roll on non-Valdo’s Tier 17 Maps.
Exclusive Tier 17 Map Modifiers now have Increased Item Rarity to Quantity ratios more in line with regular Map modifiers.
The Tier 17 Map Modifier that causes an area to contain additional Clusters of Highly Volatile Barrels has been removed. In its place, we’ve added a new Modifier that provides a chance for Rare Monsters to Fracture on death.
Added a 6th slot to the Map Device. The 5th Map Device slot is now unlocked by completing either Maven’s Invitation: The Atlas, or by completing a non-Valdo’s Tier 17 Map. The 6th slot is unlocked when you complete the other encounter.
Improved the Meteor telegraphing for the "Players are targeted by a Meteor when they use a Flask" Tier 17 Map Modifier. The Meteor also now has a 2 second cooldown.
Added 179 more foiled Tier 17 Valdo’s Map options that the Valdo’s Puzzle Box can yield.
