Raidwide AoE damage that is unavoidable. Stack up and heal through it.
Air Strike
Easily avoidable red circles on the ground. Spawns Titan Probe adds after.
Launch (Defense Sequence Three)
Titan flies up in the air and the leaves behind a rocket blast at end of channel that will hit anyone not hiding behind rocks for 21k damage. Spawns Titan Probe adds when he lands.
Missile Burst & Flame Burst (<20%)
Soft Enrage mechanic. Missile Burst is an unavoidable raidwide damage while Flame Burst is an proximity based AoE damage all around the boss. Burn the boss before your healers run out of heals
Titan Probes
Adds with 20k HPs. 2-3 spawn after every Airstrike while 6 spawn after every Launch. They do a Targeted Laser attack that deals minimal damage.
Titan 6 is a huge robot that specializes in Regional Annihilation at Reasonable Rates. This fight has a lot of raidwide AoE damage, something the healers should be aware. The fight is divided into two phases. Phase 1, which is from 100% to 20%. Phase 2, starts from 20% and is a soft enrage phase with constant AoE damage. Phase 1 is further broken up into bits in which the entire raid must hide behind rocks to avoid the massive explosion from Titan 6s rockets.
Phase 1
Phase 1 basically repeats this attack sequence over and over.
Lots of Missiles > Air Stike > Lots of Missiles > Launch
Lots of Missiles
This is an unavoidable raidwide AoE damage for 6 seconds. It ticks for 1.5k every second for about 9-10k damage in total. While Titan 6 channels this ability, everyone will get hit by missiles. This is an AoE attack so the raid should spread out while this attack is being channeled to reduce the overall raid damage. Group can stack up for heals after the channel has ended.
When starting this attack, Titan 6 will announce Initiate defense sequence two! both as an audio cue and also in your chat window.
Air Strike
This attack comes in between Lots of Missiles. It it a 2 second cast that spawns red circles on the ground that can be easily avoided. After the red circles disappear, two Titan Probes will also spawn from under the boss that will need to be killed.
Launch
Launch comes immediately after the second Lots of Missiles attack. Titan 6 will announce this attack as Initiate defense sequence three! Launch is a 8 second ability. At the end of the cast, Titan 6 will fly up in the air and the ground will be engulfed in flames. You must take shelter behind the rocks (running to the orange spot behind them will automatically put you in cover) unless you can take 21k damage or have abilities that make you immune to damage like Sorcerer/Sages Force Barrier.
When Titan 6 lands on the ground, six Titan Probes will spawn and must be dealt. Each of them have around 20k HP.
Phase 2
Phase 2 is a soft enrage mechanic. Once Titan 6 hits below 20%, he will drop down on the ground via an attack called Explosive Charge (deals around 7k damage). From here on, he will bombard the raid with Missile Burst which hits for about 2.7k damage every 3 seconds and sprays those around him with Flame Burst, a proximity based AoE attack that deals 3.6k damage every couple of seconds.
It might be helpful to spread out to lessen the raid damage from Missile Burst which is an AoE attack.
From this point on, this is mostly a race to kill Titan 6 before the raidwide AoE damage overwhelms your healers. Melee characters will take more damage due to the Flame Burst attack.
