A guide to the Tyth operation boss on Iokath released with patch 5.2.
- HP: 5.4 mil (8m)
- Enrage: ?
Mechanic Differences from Veteran Mode
- Tank swap isn’t really needed. A single tank can do fine
- No Inversion mechanic.
- You can ignore or kill some of the adds. Grace must be killed to prevent them from healing the boss but otherwise they are not really needed to remove Tyth’s rage stacks
- HP: 7 mil (8m), 14 mil (16man)
- Enrage: 9 minutes
Tyth has two cleave/AoE attacks that follow the tank. One is a simple triangular cleave and the other is a long rectangular attack called Energy Wave. Tanks can simply stand on the edge of the platform and eat these attacks.
There is a tank swapping mechanic right after Inversion where Tyth places a debuff on the current tank that increase their damage taken. The tank being swapped in must stand outside the Inversion circle so they get pulled in. Otherwise Tyth will aggro a random person and cleave them. Tyth also regularly places a stacking armor debuff on the tanks that can be cleansed off by the healers.
Tyth has a mechanic where he will gain rage stacks. These stacks will increase and decrease through the fight with a raid wiping mechanic if it reaches 10 stacks. Tyth gains 1 stack of Rage everytime an ally droid is killed (3 stacks if he killed the ally droid himself) but will autocleanse or decay one of his stacks every 8 seconds. The Grace droid also have a cleanse skill that will remove 3 stacks.
The goal of this fight is basically managing the rage stacks to ensure it never reaches 10 stacks. Once Tyth reaches 10 stacks, he will cast a raidwide AoE that deals massive damage and wipe out any remaining droids. This basically enables him to chain cast this AoE due to additional stacks from the newly killed droids.
As Tyth gain more stacks, his auto attacks (cleave and Energy Wave) get bigger in radius and becomes more likely to hit helper droids that spawn. His attacks increase in size at 3 stacks and 6 stacks.
Every 30 seconds, helper droids will spawn in waves. There are four types of helper droids. Killing any of them will grant Tyth 1 rage stack so you will need to control on when you kill them. Tyth’s AoEs can also kill them so do not drag them in front of Tyth.
- Guardian – These are just regular droids you have to kill. They have ranged attacks called Guardian Blast that hits frequently and can burst down on a raid member.
- Justice – These droids have an immunity shield called Multi-Phase Shield. These shields will damage you if you step in it and they make the Justice droid immune until you remove by it temporarily using a stun ability.
- Lance – Droids that cast a long rectangular attacks called Energy Lance that you can avoid.
- Grace – The most important droid. This droid cast two channeled skills – Avira’s Grace and Avira’s Restoration. You will need to assign a DPS or two to interrupt Avira’s Restoration, a channeled heal that removes 1 stack of Tyth’s Rage but also heal him for 3%. Avira’s Grace on the other hand, is an ability that remove 3 stacks of Tyth’s Rage and should be allowed to cast. You do not want to kill the Grace droid until the appropriate time or otherwise you may mess up Tyth’s Rage stacks and result in a raid wipe. The Grace droid will cast Avira’s Restoration 3 times before casting Avira’s Grace. A single melee DPS can handle all the interrupts using Leap/Interrupt but a Ranged DPS will need to be used as a back up during Inversion mechanic.
From 100-60%, every 30s a wave of four droids will spawn. The droid compositions are random but every even wave (i.e. wave 2, 4 6, etc) will have at least one Grace droid. Sometimes two Grace droids can spawn so you will need to have backups prepared for interrupts. Past 60%, droid waves will compose of five droids per wave and adds to the difficulty.
You want to time your kills so that the Grace droids can remove any stacks of Tyth’s Rage before being killed. This allow you to kill the Grace droid, wait for the decay, and then start the next droid wave without any stacks.
Inversion is a mechanic exclusive to hard mode. 20 seconds into the fight and every 40 seconds after, Tyth will cast an inversion skill. This skill will pull all raid members on the platform to Tyth unless they are already inside the Inversion circle.This is a 5 seconds channel so you have 5 seconds to get into the circle.
If you are not inside the Inversion circle at end of the channel, you will get pulled into Tyth and receive a debuff that reduce your damage and healing. If you are already inside the circle at end of the channel, you will get thrown out of the circle and instead get a buff that increases your damage and healing. What the tank want to do is to position Tyth right at edge of the platform and have everyone run inside the inversion circle to the edge of the platform right in front of Tyth. This will get them thrown to the middle of the platform with the damage/healing buff.
One important note about Inversion is that it will block all movement/gap closer skills for a few seconds so you cannot use skills such as Force Speed/Force Barrier/Leap etc. During this you will need to have a ranged DPS focusing interrupts on the Grace droid as melee cannot leap back to the Grace droids in time to interrupt the heals.
As Tyth get to 30%, you may choose to ignore all the adds but the Grace and do a final burn on Tyth. Healers will need to run around and kite the adds while rest of the raid focused on killing Tyth before its adds overwhelm the raid. Remember that past 60% Tyth summon droids that comes in waves of 5 so the Rage stacks accumulate faster and you have very little margin for error. It ultimately comes down to your group DPS as this tactic may not work if the DPS is lacking.
