You will hide in the front left corner face into the room so your npcs are ahead of you. Mobs that spawn will run past you and pool in the center, wait until they are all pooled together then shoot them & your tank npc should run into them / use his aggro skill before they all get to you. There may be some extras that did not get caught, you just need to run around your tank NPC until he uses his threat ability.
Rinse and repeat including the mini boss, dps it when it is safe.
Second Room
Before entering this room you are going to mount up, then proceed to charge in. Collect all the mobs and then run in circles around your tank npc until he picks them up, when he has them you will dps the mini boss, repeating the running process if extra adds spawn and go for you. It is okay to use your AoE abilities if the tank npc has threat.
Third Room
Just like the first room you are going to immediately go into the left (or right) corner and wait for the mobs to pool, AoE when they are together and let your tank do his business / kite as necessary. This is rinse and repeat even when the mini boss & main boss spawn.
Class Advice
Aeore Healer
Keep Fairy up on yourself prior to doing your Mass Dark Veil on the mob group, just in case. You don't have to but you can use Mass Fatal Sleep on the mob group, particularly in Room 2 & 3, so the mobs are right on the tank and have the threat ability used on them without you needing to kite. Dark Backfire & Mark of Lumi on the mini bosses and main boss whenever it is safe to do so, it helps.
Do not let yourself get low hp, use Panic Heal whenever the main boss punches you in the face & make use of your Celestial Shield + Dissolve skills in particular. Keep max range from the boss to avoid Boss Fear, which can become a dangerous situation if he decides to hit you during this time too. Use Tree / Lumi pet at your discretion, I prefer tree but only really use it during the poison phase in first room.
Buff all of your helper NPCs at the start!
Give yourself Emblem of Salvation!
Alternate strat: Heavy armor + Wizard Harmony, this went very smoothly and I've been using it the past few days, you have a faster kill time too. Much less stressful!
Wynn Summoner
Use your Reaper pets, keep up your self buffs + transfer pain, use your Reaper AoE ability to pull the groups. Use your debuffs on the mini bosses & main boss, every little bit helps.
Bears are actually pretty awesome on minion waves, but truly suck on the bosses. You could use them for the first room and last room, unsummoning them and going back to reapers at wave 7, send them in and use their AoE ability, heal them like the little tanks they are BUT I daresay this is over complicating it.

With the pooling tactic you should be able to have 90% of the mobs down in two big AoEs, use your teleport skill to avoid being hit. -Sercatum in another thread, http://boards.lineage2.com/showthread.php?t=236668

Bottom of page 1 Dreamer has made a specific strategy for Tyrr, enjoy and thank you!

for the most part turn on rapid stance, AOE mobs and kite as necessary. Bosses you will kite until tank has aggro, then use Siege stance and spam skills. - courtesy of juicebox09

Iss Enchanter
You might consider staying with the prisoners at the top of the stairs in the first room and keeping them alive / fighting there, you are pretty durable and lack a ranged aoe for the pooling tactic + there will be less kartia guards to fight. - information from Darkwings, ty!
Polymorph is a great skill, make use of it but remember that you will not be healed by the NPC in this form. Don't forget to try and keep up shadow blade debuff! -courtesy of electra07
There are several more detailed, fairly large posts on page 1 below this that you may want to look at!
General Tips
- Don't be Cheap, buy ISS buffs! Get KNIGHT HARMONY! It helps a ton.
Emblem of Salvation / Blessing of Noblesse can save you a half hour if you make one small mistake and get killed, if it's available get it / use it!
Better to hold your DPS and go slower than to die.

Sometimes in the rooms you may not aggro all of the mobs, use this to your advantage and kill the ones that are attacking before cleaning up the others! -courtesy of electra07
For stage 4(or 5) when the mini boss in the 3rd room spawns, you can leave 1 mob alive while you kill the mini boss so you don't need to deal with it + the next wave. - courtesy of juicebox09
If your npcs are stuck in the first room, take a good look around, odds are there is a mob or two left there somewhere. If not, well nobody claims it's a bug free instance.
Your npc helpers seem to be much more active if you keep a (living) mob targeted, try it out.
