The raid setup can be a 2 of each setup. its all about assigning jobs.
first off you need to assign 12 members to perform combinations to pull bosses, and 6 different members to perform golden constellations, and 1 beacon holder. this leaves 5 members that can be backups.
After members perform a constellation , they will get a debuffs that prevents them from doing it again for 45s.
We do the following order:
Winter- Arctic boss
Spring- Thaw boss
Summer- Swelter boss
Autumn- Harvester boss
Each of these bosses will get dmg buffed if he comes in contact with the corresponding spirit and debuffed if he comes in contact with the opposite spirit.
Example. Winter vs summer / spring vs autumn
Each of the bosses casts meteor spell, this spell is targeted on ''beacon'' holder, this spell will do 8k dmg(tanks) per second to any member standing between him and beacon. the beacon is always auto-taken by person furthest from boss. a big tip here especially to melee dps/tanks is that this spell is a 180 Degree line dmg and is quite wide, its a good idea to stand clear from his front when he turns to do it.
Each of these bosses will also perform a AoE 1shot that is interrupted by keeping him +- 6/7 meter close to the opposite spirit.
The spirits are CC'able, and for a brief moment they will chance direction after CC'd and resume normal rotation after 3/4 secs.
We start by pulling Arctic first,the 12 members do the constellation, boss comes out (bosses Spawn ALWAYS near The Emperor), we pull it to summer spirit Asap. as this is being done the ''beacon'' moves to the door(close to winter spirit), this member must only focus on keeping distance from the actual boss, and keeping the line between him and boss not cross the middle pads, so that the 6man group can safely perform their constellations.
As soon as the 12 man group exits the central pad, the 6 man group goes in and performs the constellation in order to give the raid immunities against channelling spells from emperor*. They receive a 45s debuffs that prevents them from doing constellation, and emperor will start a new one every 50s, so the golden group must be fast in order to not have debuff for next constellation.
*we dont have all the spells he channels on record but its a variety that includes: aoe magic dmg, +hate, -hit rating, -speed.
Also the boss always starts with meteor followed by a AOE 1shot after a few secs.
We keep the raid in front of the boss on the path of the spirit we tank it on, we always keep boss with symbol as it rotates, however we try to control Spirit so we have to do it as Least as possible. This kinda control requires us to keep 1 Ranged DPS near buffing spirit that tried to CC lock it (1 demo/ranger) in order to keep distances from each spirit, to prevent them going together wich would buff boss.
These bosses have huge volume, and so they frequently move around, its important to both tanks and beacon to adjust as fast as possible. tanks hugging the boss, and NOT using dread shadows helped us ALOT to keep boss in place.
After each boss is dead, members not performing constellation should go ensure that the next relevant symbols are far apart, also remember that the symbols DON'T return to their spawn points after any boss is dead. and aggro'ing tank need to be always aware where the relevant symbol is.
Also keep in mind that if the golden constellation was performed shortly before boss was killed, summoning the next boss should be delayed till the golden group has maximum 15 sec CD on buff.
Also don't forget that you only have about 30 secs to summon next boss, if u fail to pull, The Emperor will casts massive Aoe on group ending boss-fight.
About golden constellations also need to add, each individual boss can have 2 different constellations and these will be also active on next boss you pull, so for example:
you start with artic you will have 2 different ones.
I you pull Thaw after you will have the 2 from artic + 2 new ones from Thaw.
So pretty much last pull is 8 different golden constellations.
Each constellation corresponds to a specific spell from Emperor, ATM we don't have them on record.
We killed the following bosses by following these ''simple'' guidelines. each fight is pretty much the same logic. And also, the fun part, you got 10 min to kill all bosses
