Runes of Magic US / AU

Recommended Group Composition: 1 priest + 1 other healer (priest, druid,w/e). Some kind of off-tank, can be wd/w, could be a geared c/p, or k/p. This is to help with trash as well as being a target for certain boss skills that kill dps players. No macro'd alts.
We were able to down bosses 1 and boss 3 with what could be considered a sub-par party (some players undergeared, 2 healers, no c/p k/p buffs, etc.)

Trash:
Focus single target damage on the big ugly guys first, making sure to keep them silenced or disabled at all times. They cast a frontal aoe that also is a knockdown, and if you pull two of these at once without silencing your raid dies. For the large group before you turn the corner before first boss, you can avoid pulling the Mages (who stun their target) as long as you don't run up to them.

Silencing some mobs when they are at their peak patrol point will let you pull smaller groups in some places. When pulling 10 mobs is unavoidable, just wait for your 3min cds and go in with burns.

--more to come as I run the instance more often.

1st Boss:
Sanbresha Gordy only has 171m hp, Burn this one with cds first. After that, simply avoid Lorl Gordy when he is using his aoe (he is covered by some wind effect skill). Fairly Simple.

2nd boss: *shrug*, haven't tried yet.

3rd boss: Slogar
10 Minute Rage Timer. If you can't kill him in this duration, you need more practice and/or better dps players.

-Keep boss out of the middle grates (kite him aruond the outside as needed). Anytime he passes over them, he gains stacks of a debuff which allows him to drop fires on the ground that fear players (debuff has a fire icon). If you keep him stationary, these fires will be underneath him, and fear players within 40~ range (white hit melee range). You can go so far as to use an Invisibility Potion to make it so he has 0 stacks at the start of the fight, but can be done without the use of invis potion.

-Players Standing in the middle grates take some burn damage. The fear can make you run into this, which is why the tank needs to make sure the boss, and no other players, run into the middle of the room, and why the dps need to be mindful of their positioning.

-He will gain 10 stacks of an immune buff. While this is active, I was not able to taunt or apply any debuffs to the boss. Have your dps (and only dps) click the objects around the room. Clicking the objects makes the player unable to move, and possibly unable to cast spells, but gives a medium-ranged Alternate Skill that removes 1 stack. Remove 10 stacks to be able to damage the boss

-He will Cast a spell called "Rage Mode". When he does not have his shields up, this skill can be interrupted (throat attack, silence, lightning all seemed to work). If you don't interrupt this skill, the boss gains tremendous damage output, and will most likely need to be kited by the tank. He hit me for 400k+ with 620k pdef with just a basic attack.

-Periodically Casts "Steel Porcine Blow", which targets the second highest aggro player. This ability is a linear aoe (think cross chop, phoenix, etc), hitting all units inetween the boss and the target. Have a second tank purposefully position himself on the opposite side of the room of the boss, so that this aoe passes through the middle of the room where no players should be.

-Periodically casts Rusty Iron Blade, a close range 360 aoe ability. This will stun for 5s~ and possibly kill nearby players, but most importantly, if he tank gets ht by this, the boss switches aggro. It isn't a complete aggro reset, but for the duration of the stun, the boss will ignore the tank and slaughter your companions.

-The tank gains a 50s duration, stacking debuff, roughly once per 20s. This debuff greatly increases damage done. This is the reason for the Priest Selection in group composition -- this player can cleanse the debuff, and it is EXTREMELY important this is done quickly. This debuff + rage mode can result in huge damage taken by the tank.

-classes like m/s, m/r, wl/c should in theory, be fantastic here. Ranged, sustained, damage dealer who doesn't need to worry about the fear fires dropped on the ground, that can move while attacking to avoid aoe damage.

Execution: Ensure off tank is second in aggro at all times. Aggro boss without pulling him through center, and keep him outside the middle grates at all times. Tank MUST avoid the Rusty Iron Blade aoe skill, or boss attacks other players. DPS click clubs and remove defense stacks as needed. Silence/interrupt RAGE MODE when boss isn't immune, if he finishes cast, use speed buffs, or all defense cds, and kite. Healer needs to constantly remove the debuff. Offtank positions him/herself such that no other players are betweeh them and the boss, when it casts Steel Porcine Blow. Co-ordinate cooldowns to to max damage when boss is vulnerable.

Here's a vid from the offtank wd/w perspective: https://www.youtube.com/watch?v=I_VSLg_eG_E&feature=youtu.be

4th Boss: Old Dan Gordy (incomplete):
-boss uses a frontal aoe. Turn him away from party
-3 debuffs get placed on random players in the group. Broken Soul, and Torn soul, both deal damage and/or kill the player afflicted when they expire. The third debuff, Devour Soul, gives a 1 use alternate skill to remove the previous debuffs. Upon use, a new player gains this debuff.

Ths macro will cast the alt skill to remove debuffs, but with only one attempt using it, we have not yet killed the boss.

Quoted from "ShaWalker"

This 'Rusty Iron Blade' seems a 2 second cast, but when i try to run away (when I'm tanking here), I'm already stunned in the first second of the cast, it looks that the stun is applied earlier? Or maybe its just lag, i need to test it more tho.

Its definitely lag, the stun is not applied until you get hit by the skill. The range isn't that far either, maybe 50 or 100 at most from boss.

Also, specific to third boss, the 3 tiems we downed him, we burned him to 30-40% before his first immune. He has a 10 minute rage timer, and unless you're bringing classes like w/m or maybe a bunch of well geared m/s, you won't get through 50+% hp in that time.

I have modified the given macro as such.

I didn't consider what happens when position 12 gets the debuff....With previous setting, he/she would never get targetted by another player, since there is always someone before them to have skill cast on. With new time setting, this will help remove debuff from any position, not just the first 6-8 players in raid. Thanks for suggestion.

preliminary poking of 5th boss on ez mode suggests its a "ranged classes win" fight. During the fight he will place a debuff on some players. This debuff causes the skill he's constantly casting, Undead Worship, to 1 shot you if you get hit while the debuff is in effect. Undead Worship, however, has a limited range, so melee need to constanty run away from it while ranged characters can sit in one spot.

He spawns some adds when you have people within melee range at certain times, but again, this is another thing that didn't happen when our group stayed far away from boss. I guess mages/scouts ftw here? Will post more information with more detail if/when we attempt this on hard mode.

We tried on easy mode having only a centaur hit the boss. It took damage slowly and eventually died. Unsure if the damage taken was due to having aggro, or someting that will happen regardless of aggro or not. Damage didn't show up in combt log, it just slowly died.
