Marcus Tex

Strategy
This mob is laying on a sort of experimental table, arount this table 5 nameds Vampires. Around the central room with these mobs, a circular corridor, around this corridor 5 rooms, alcove style Marcus Tex and the 5 nameds are not aggro.

Each of the 5 nameds has a symbol on his cloak, each of the 5 rooms has a symbol on its floor.

You must fight each of the 5 nameds, one at a time, in the room with the same symbol, when the mob is dead the symbol on the floor glow.

Each time you kill one of the 5 nameds it buffed the still living nameds, but even the last named is not too difficult.

When all the 5 nameds are dead Marcus Tex become aggro.

A few remark on this mob
 * He take damage only in the central room
 * The room and the mob spam 3 dirty AE
 * The five chairs where the previous 5 nameds where standing are now clickable, each one give a specific bonus. Below the one "mandatory" for the fight of Marcus
 * Create a pet
 * Prevent AE of a certain type

Here is the way we managed to kill it pretty easily Start the fight in the central room. When the walls of the central room start glowing with runes leave the central room and backup in the corridor, but do not stay in front of the door of the central room. The best is to have the MT on one side of the door, heals and DPS on the other side. Just after you backup in the corridor you will see 3 flash of light comming through the door, this is the 3 nasty AE. When the flash of light are gone you can enter the central room again to continue damage Marcus. During the fight Marcus will charmed one of you, do not remember the percentage of life when he do this, be sure to have the bonus pet up, Marcus will charmed it and let you free, do not bother this mob he is not worth the pain. Marcus will do this twice the fight. During the fight Marcus will spam an acid rain AE, you can survey this because it has a quite visible green cloud animation over your head, when you see this activate the anti-AE bonus, it could be quite useful to have more than one person to have this bonus just in case. Do not know what triggers this AE.
