Hotfixes: October 6 (Source)
Mythic Keystone Dungeons
- (Destruction) Dimensional Rift will no longer spawn portals that are out of range to do damage to your target.
- The amount of Artifact Power rewarded from end-of-run Mythic Keystone chests now increases with the Level of the Mythic Keystone Dungeon.
- When beating a Mythic Keystone timer by a margin so significant that your Keystone is upgraded by more than one step, you will earn multiple loot chests as before, however, the additional chests beyond the first will no longer contain Artifact Power.
- Developers’ Notes: These changes are aimed at aligning the efficiency of the different tiers of difficulty, so that a well-geared group of dungeon experts is rewarded more for tackling a high-level Mythic dungeon, rather than incentivized to stomp an entry-level dungeon.
- The Archaeology World Quest heirloom reward Spear of Rethu should now be item level 700, as intended (was item level 605).
