Basic Overview
Overview
Coratanni fight is divided into two distinctive phases. In the first phase you will fight Coratanni and Pearl. This is a two tank encounter with an interesting Ricochet Shot mechanic to prevent players from standing too close to each other. You will want to get Pearl to a low% before pushing Cortanni to 19% as she will escape and cause Pearl to enrage (if you kill Pearl first, Coratanni will enrage). Use the escape pod to get to phase 2 where you will face off against Ruugar. Avoid stacking too close as Ruugar throws out AoE Corrosive Grenades, Land Mines, and explosive Death Mouse droids. If Ruugar holds someone hostage, stop attacking Ruugar or you will transfer all the damage to that player. Fight is finished at 7% when Ruugar self-destructs the ship.

Basic Mechanics
| Mechanic | Description |
| Ricochet Shot | Ricochet Shot is an ability casted by Coratanni every 10s with a 2.5s cast time to a random raid member. It applies a debuff called Double Down that will also spread to the nearest player to the targeted person. If they get hit again with Ricochet Shot with Double Down debuff, they will likely get instantly one shot. |
| Suppressive Fire | 3.0s channeled conal attack with a big telegraph, need to face Coratanni away from the raid. 15s cooldown. |
| Flame Grenade | Casted every 30s starting at 30s into the fight. Flame Grenade applies a burning debuff to everyone in the raid. You can remove this by using the panels in the back to spawn blue circles to remove the buff. |
| Corrosive Grenade | Poison DoT applied to a random target. 15s CD. Very low damage and can be ignored. |
| Deck Guns | Four cannons will activate on a 20s cooldown one side of the room when Coratanni reaches 66%. They have big yellow telegraphs you need to avoid. |
| Acid Spit | Conal attack from Pearl, need to turn him away from the raid as well. 15s cooldown with 2s cast time. |
| Frenzied Onslaught | 4.5s channel from Pearl that pins the target down. 30s cooldown. |
| Pearl’s Poison | DoT applied to whoever Pearl is attacking. 30s cooldown |
| Activating | At exactly 732192 HP (around 18-19%), Coratanni will stop taking damage and run to the escape pod. You have a few seconds to kill Pearl before he enrages and deals 300% more damage. |
| Land Mine | Orange circles placed on the ground by Ruugar, anyone stepping inside them will get a Burned DoT |
| Corrosive Grenade | AoE poison around the target from Ruugar, can be cleansed. 15s cooldown. |
| Corrosive Dart | A stacking DoT from Ruugar applied to the target with main threat. 10s cooldown. Tank swap mechanic |
| Cull | 3.0s channeled attack from Ruugar with 20s cooldown. May force a tank swap since it causes all poison DoTs on the target to deal damage as well. |
| Knockback | Standard knockback from Ruugar, 30s cooldown. |
| Hostage Situation | Ruugar grabs a random raid member, any damage dealt to Ruugar will be transferred to that raid member. 60s cooldown. |

Detailed Mechanics
Cortanni and Pearl
Both bosses will need to be tanked so two tanks are required here. There isn’t any tank swapping mechanic on storymode but Pearl will become immune to taunts from time to time and go after random raid members. The tank will need to grab Pearl back.
Cortanni’s filler attacks is mostly Ranged Attack while Pearl’s are a combination of Swoop and Peck.
Ricochet Shot
Ricochet Shot is an interesting mechanic. Coratanni will target a random raid member and casts Ricochet Shot, which has a cast time of 2.5 and a cooldown of 10s. The ability itself doesn’t seem to do any damage but it applies two debuffs on you: Double Down and Split City.
Double Down lasts for around 20s and Split City lasts for 8s. Split City will apply Double Down to the raid member nearest to the player with the Double Down debuff. This will cause two raid members to have this Double Down debuff with every Ricochet Shot attack.
If you get hit by Ricochet Shot again with the Double Down debuff, you will take quite a bit of damage and might be instantly killed. Coratanni won’t target the same person again for the next Ricochet Shot but she might have a chance to target the player who received Double Down debuff via Split City.
To counter this, everyone should spread out to avoid getting hit a second time by the Ricochet Shot mechanic. If you know who is the target of this Ricochet Shot mechanic, move away from them.
Suppressive Fire/Acid Spit
Suppressive Fire and Acid Spit are two telegraphed conal attacks from Coratanni and Pearl respectively. They should all be pointed away from the raid to prevent unnecessary cleaves and raid damage.
Flame Grenade
About every 30s starting at 30s into the fight, Coratanni will apply the Flame Grenade debuff to everyone in the raid. It ticks for about ~4k damage every 3 seconds. If your raid team is decently geared, you can ignore this as it doesn’t do a lot of damage. Otherwise, you can have one person go to the panel in the back to spawn blue circles in the room. Step inside the blue circles to remove the Flame Grenade DoT.
Deck Guns
Four cannons will activate from a specific place in the room when Cortanni reaches 66% HP and every 20s after that. Their telegraphs cover the width of the room so you will need to find gaps between the telegraphs to avoid damage. They do quite a bit of damage and has a knockback component if you do get hit.
Corrosive Grenade/Pearl’s Poison
Both Coratanni and Pearl have a poison DoT attack. Coratanni applies Corrosive Grenade attack to a random raid member on a 15s cooldown that deals around 4k damage every 3 seconds. Pearl applies a long last Pearls Poison DoT to the tank that deals about 2k damage every second on a 30s cooldown.
The damage these DoTs deal is fairly low on storymode. Unsure if either of them can be cleansed.
Activating and Enrage
Once Coratanni reaches 732192 HP (around 18-19%), she will stop taking damage and run to the escape pod to cast Activating. There is nothing you can do to stop her but you will need to kill Pearl ASAP as it will enrage in a few seconds and deal 300% more damage. You want to bring Pearl quite low but not enough to kill it and then bring Coratanni to that HP mark to enter the next phase of the fight.
- If you kill Pearl first, Coratanni will enrage
You can survive a few seconds with enrage if your raid screwed up but it is not recommended as you may lose players for the next phase and stealth rez is not reliable here.
Once you killed Pearl, have everyone click on the Escape Pod to transition to the next phase.
Land Mine/Corrosive Grenade
Ruugar will drop Land Mines (yellow circles that turns orange) on top of raid members. If you step into these circles, you get a burning debuff. These circles can pose a problem for melee but for ranged they are fairly easy to avoid.
Ruugar also have an AoE attack called Corrosive Grenade that target a single player and anyone around them. This grenade can be cleansed but it is on a 15s cooldown so it is fairly frequent. To reduce the amount of players that get this DoT, have everyone spread out.
Death Mouse
To further encourage everyone to spread out on this fight, there is Death Mouse droid that spawns on a 25-30s timer and will run to a random person in the raid to explode on them. The explosion will hit for about ~20k damage so if everyone is stacked up, it is quite a lot of raid damage.
Corrosive Dart and Cull
This is potentially a tank swap mechanic in hardmode but it is ignorable in storymode. Ruugar will apply a stacking Corrosive Dart dot to the tank with main threat and follow it up with Cull. Cull will cause any poison effects on the target to also deal damage. So if you are the main tank with stacks of Corrosive Darts and possibility a Corrosive Grenade, Cull will hurt quite a bit.
The damage increase isn’t noticeable in storymode so we do not do tank swaps here.
Hostage Situation
Hostage Situation is a fun mechanic. It is a debuff applied to a random raid member for 5s with a 60s cooldown. Whoever has this debuff will absorb all the damage done to Ruugar for the duration of this debuff. This is a raid awareness check on your DPS but can be a source of fun to try and kill the debuffed person before it wears off.
Strategy
Phase 1
Have tanks grab Coratanni and Pearl and turn them away from raid to prevent their Suppressive Fire and Acid Spit from cleaving the raid. Raid need to spread out to avoid getting Down Under debuff from Ricochet Shot. The goal here is to get Pearl to a low % (i.e. ~10) before damaging Coratanni too much. Avoid the Deck Gun telegraphs and use the console to remove Flame Grenade DoT if the damage is too much. Coratanni will escape at ~19% and Pearl will enrage a few seconds after that. Tanks should prepare their cooldowns for this enrage.
After finishing off Pearl, have everyone interact with the escape pod to get ported to the next area.
Phase 2
Finish off the elite adds before engaging Ruugar. Avoid the land mines from Ruugar and spread out to lessen the raid damage from Corrosive Grenade and Death Mouse. Depending on your tank/healers, you may or may not need a tank swap when stacks of Corrosive Dart get too high. Watch the screen and if you see the red text of someone getting held hostage, stop attacking Ruugar for 5 seconds.
At 7%, Ruugar will activate self-destruct and the fight is finished.
