Keystone Dungeons

Mythic Keystones

• A Mythic Keystone is a special item used to begin a Mythic Keystone Dungeon.
• Each Keystone is attuned to a specific dungeon and has a Mythic Level.
• The Mythic Level of a Keystone determines dungeon difficulty and which affixes are active.
• A character can only have one Keystone at a time.

Obtaining a Mythic Keystone

• Completing a Mythic dungeon grants a Mythic Keystone.
• Completing another player's Mythic Keystone dungeon grants a Mythic Keystone at the end of the dungeon.
• After the weekly reset, opening the Great Vault grants a Mythic Keystone if a Mythic Keystone dungeon was completed in the prior week.

Downgrading a Mythic Keystone

• Failing to complete the dungeon within the time limit lowers that Keystone's Mythic Level by 1.
• Resetting the dungeon instance after the Keystone has been used lowers that Keystone's Mythic Level by 1.
• Lindormi in major cities can lower a Keystone by 1 Mythic Level on request.

Starting a Mythic Keystone

• Enter the dungeon the Mythic Keystone is attuned to on Mythic difficulty.
• At the entrance, insert the Mythic Keystone into the Font of Power and activate it to start the dungeon.

Replacing a Mythic Keystone

• When a Mythic Keystone dungeon is completed within the time limit, Lindormi can exchange a character's Keystone for one attuned to a different dungeon. To be eligible for exchange, the completed dungeon's Mythic Level must be equal to or higher than the Keystone being exchanged.

Completing a Mythic Keystone

• All bosses must be defeated.
• The enemy forces requirement must be met by defeating non-boss enemies.

Upgrading a Mythic Keystone

• Completing a Mythic Keystone dungeon within the time limit upgrades that Keystone's Mythic Level.
• If less than 20% of the timer remains, the Keystone upgrades by 1 Mythic Level.
• If 20% to 40% of the timer remains, the Keystone upgrades by 2 Mythic Levels.
• If more than 40% of the timer remains, the Keystone upgrades by 3 Mythic Levels.

Resilient Keystones

• Starting at Mythic Level 12, completing all current season Keystone dungeons within the time limit sets a character's Resilient Level to that Mythic Level for the rest of the season.
• If all current season Keystone dungeons are later completed within the time limit at a higher Mythic Level, the character's Resilient Level increases to that higher level.
• A Resilient Keystone does not drop below its Resilient Level when a dungeon is not completed within the time limit. A Keystone's Mythic Level can still be lowered by speaking to Lindormi.
