Editing Defeat Hoshino Kei (section)

=== Part 5: Private Quarters ===
# Ahead, you will fight a few more spawns and at last reach the Private Quarters portal. The drop is safe.
# You will now be in a large room with the [[Spirit of Bist'elle]] and a mnemosyne. DO NOT click on the mnemosyne unless ready to begin combat. Everyone in the group can talk to her (unknown if this is required).    
# This fight requires teamwork. By clicking the mnemosyne, the room will be filled with creatures on a fast respawn. An NPC form of Hoshino Kei will also spawn next to the mnemosyne. DO NOT at any time speak to her - she will portal you to [[Fort Tethana]]. The goal is to kill three large ward crystals (Blight, Decay, and Darkness) that will also spawn in separate locations in this room. Archers can machine gun the crystals but they are immune to life magic. Once each crystal dies, it will be replaced by an NPC that you must protect. If the NPC dies, the crystal will respawn and you will have to kill it again. Note that you cannot heal the NPC and must instead kill the spawns that attack it.
# The suggested strategy is to remain near the middle of the room and bring each crystal down to very low HP before killing them all simultaneously. This will save you from having to defend each NPC while some of the crystals are still alive.
# Once all crystals are dead, and all NPCs remain alive for 5min, Hoshino Kei will become vulnerable and the NPCs you were defending will despawn, but the monster respawns will continue.
# You can imperil and vul the [[Materialized Hoshino Kei]], but she will dispell constantly (it is a level 8 dispell). You may choose to assign a dedicated vuler. Keep in mind she has very high magic defense and 500k HP (HP is unconfirmed). She can also dispel your buffs (including rares!). Hoshino sticks to the center of the room mostly, however, if she targets a player on the edge of the room with a ring spell she will move to them.
# Once dead, pick up a {{Itemlink|Mirror Shard}} from her body. She drops 9. These shards are turned in to the [[Spirit of Bist'elle]] who will give you a key to a reward chest, as well as the XP and luminance rewards, then portal you to the chest room. 
# Loot the [[Legendary Empowered Robe of Utter Darkness]] from the altar in the NE corner, then use the key to loot the chest of your choice.
