Omens of War
Progression
The Omens of War expansion is part of EQ Might's progression. To complete Tier 9, you have to defeat Arch Magus Vangl.
Defeating Overlord Mata Muram is optional.
Omens of War offers access to the Epic weapons version 1.5 and 2.0. For knights, there is an addtional quest to unlock the one-handed Epic 2.0 weapons.
Access to Citadel of Anguish
In order to enter the Citadel of Anguish, a player must be level 66 or higher and be in possession of the item "Seal: Mastery of All".
The "Seal: Mastery if All" is dropped in any of the regular Muramite Proving Ground Raid Trials. There is also a chance that the seal drops in the solo/duo instance "Mastery of Versatility".
Lockouts:
Muramite Proving Grounds Group Trials: 3 hours, plus 1 day if won
Muramite Proving Grounds Raid Trials: 3 hours, plus 2 days if won
Boss NPCs in Citadel of Anguish: 5 days
Anguish
The instance for Anguish can get in two ways:
At the usual place in Walls of Slaughter, by clicking on the gate to Anguish. This is a "regular" expedition of the zone. It supports 2-20 players. It does not support the Aura of Might.
Through Howard in Plane of Knowledge. This is an EQ-Might specific instance of the zone. It supports the Aura of Might, but it does not spawn legendary loot for AMV and it does not spawn the OOM event. (The reason for it not spawning OMM, is that OMM directly drops Reliquaries and is intended to be fought with no more than 20 players. This instance, however, does not limit the number of players.) For teams of 6 or less, it is highly recommended to get this instance.
Epics 1.5 and 2.0
If you completed the Epic 1.0 quest or acquired your Epic weapon(s) 1.0 from Cloe, you can skip the 1.5 pre-quest.
Once you are in possession of the Epic 1.5 or 2.0, you can talk to Alisha in Plane of Knowledge to collect an Epic ornamentation.
OOW Tier 2 Quest Armor
Tier 2 armor pieces for chest and helmet feature a slot for type 15 augmentations. The other armor pieces are standard.
Teleports
There are various cross-zone and in-zone teleports available, some of which have to be unlocked.
Plane of Knowledge
Howard offers teleports to:
Bloodfields
Dranik's Scar
Riftseeker's Sanctum (requires level 65 to enter)
Wall of Slaughter (by entrance to Citadel of Anguish)
Wall of Slaughter (by zoneline to Nobels' Causway)
Items
