Breachstones can be empowered using the respective Breachlord's Blessing on it, turning it into the Flawless variant. The area of a Flawless breachstone offers an increase in quantity and rarity of items found, as well as an increase in monster level, monster experience and monster pack size over its regular counterpart. Flawless Breachstones also spawn with additional modifiers and grants less additional time from monster kills.
How to get Flawless Breachstone
Flawless Breachstones no longer drop from Maven Invitations.
Breach Blessings can now be used to upgrade a regular Breachstone into the Flawless version of that Breachstone. Breach Blessings are now rarer as a result.
The Within Their Grasp Notable Atlas Passive no longer provides chances for Breachstones dropped by Breach Bosses in your Maps to be Charged, Enriched or Pure. Instead, it now causes Breachstones dropped by Breach Bosses in your Maps to have a 5% chance to be Flawless. It also now causes Breach Bosses Defeated in your Maps to have 4% chance to drop a Breachstone (previously 12%).
Flawless Breachstone Bosses can no longer drop Breach Blessings or un-upgraded Breach Uniques. They now have a chance to drop upgraded Breach Uniques.
In Path of Exile: Crucible, we're raising the area levels of Breachstones to a much higher baseline level - 81 for elemental ones, 82 for physical and 83 for chaos. Now that the regular Breachstones are much higher level. We have retired Charged, Enriched and Pure Breachstones. They will be converted to regular ones.
