Availbility: Once a game month, on the 13th at midnight (midnight of 12/13 or 13/14 - TBC).
Recommended that you have 3 Archons, as once Mharizad, The Elder Vampire is in the towne of Rune he will bit mobs and turn them into copies of himself if they are not killed quickly, which also need to be killed before you can kill him.
You will need to acquire a holy silver cross from Tower of Art to start this run, the cross can be found up in the CPK zone of the tower, through the only west door and then the first north, search to find it. Currently the cross decays rapidly, so you can not store it for long, should you get one, you need to head to the towne of New Rigel to Indra Temple.
Indra Temple can be found all south on Lewis Street, the final west door, head inside, west, west, then north and you will see a down. Say "In the name of the dark powers let me pass" this will unlock the down door, head in and place the cross into the coffin (this needs to be done between 7pm and midnight, and likely requires one full moon - TBC), this will release Mharizad, The Elder Vampire. You will then need to hurry to the towne of Rune.
Preparation
Check mems, reagents and be ready in the towne of Rune for midnight. Killing off as many of the local mobs will save you a bit of time hunting down the copies of Mharizad, The Elder Vampire.
