Patch 12.1 and Midnight Season 2 bring a brand new way to fight World Bosses by… well, removing the world! Each World Boss will now have its own Lair, an instanced version where players can up the difficulty all the way to Mythic!
The encounters will have two parts. There’s a starter where you’re defeating elites so that enough players can gather, and then there’s the main boss fight. These encounters can be undertaken by groups of 5 to 40 players for most difficulties. Mythic will require 15 to 25 players, however. These Lairs will be accessed via summoning stones at the bosses’ open world locations. Lairs will unlock the base, Normal difficulty, with the patch launch. The rest of the difficulties will arrive a week later with Season 2’s launch.
The loot will scale accordingly, all the way up to Mythic 1/8. There’s a full breakdown of the loot and achievements below. So far we’re just getting the one boss, Nymrissa Wavecaller, in the Tidebound Grotto, so let’s see what she’s all about!
Step into Lairs, a new evolution of world boss encounters that gets you into the action faster. Enter a monster’s lair on World difficulty to join a dedicated instanced encounter with other players, rally your allies, and take on fearsome bosses without the wait or heavy coordination.
These bosses will scale in difficulty through Normal, Heroic, and Mythic (15-25), allowing coordinated raid groups to also take on these new challenges.
Where There’s a Lair, There’s a Way
Similar to Delves, Lairs are found in specific locations throughout the zone, with an available summoning stone just outside the instance making it easier for players to take on these bosses at a difficulty of your choice.
Queuing Solo?
After selecting World difficulty and pressing Enter, you’re delivered straight into the Lair while players gather around you. While waiting for other participants to enter, champions enter a two-part scenario while the instance automatically fills up with additional challengers.
The first part of the scenario calls heroes to take down elite monsters until the Boss appears, but have no fear, you won’t be soloing the boss. This just ensures a certain critical mass before the second part of the scenario can begin. Boss difficulty scales between 5-40 players, ensuring that a large range of group sizes can walk away with epic loot.
Groups
For pre-made groups, the leader must choose the difficulty and enter first. Once inside, the rest of the group can follow as the raid group fills around you.
Higher Difficulties
Lairs are also available for organized pre-made groups on Normal, Heroic, and Mythic (15-25) difficulties, letting groups of all sizes enjoy these new encounters. Lairs employ a scaling difficulty even on Mythic, allowing tons of flexibility in whom you bring along.
Dive Into The Tidebound Grotto
Brave champions must make their way to the Tidebound Grotto, but get ready to hold your breath because you’ll need to swim down to the Lair entrance in the waters below The Coiled Isle. If you have an aquatic mount, now’s the time to make good use of it!
