Raid must be divided into four groups, each with 2 players (i.e. Tank/dps or healer/dps pairs). Each team must make to their designated location and kill the two NPCs there concurrently. You have to 10 minutes to get to do this and the timer stops when you engage Operations Chief
Terminate (Operations Chief)
Single target attack that deals massive damage. One shot anyone not a tank. Use defensive cooldowns if you are low on health to survive through it
Mass Explosive Probe
Raidwide damage.
Rail Turrets
Four adds that spawn in the room with low HP.
Operations Chief is a multi stage fight that requires you to infiltrate the Oasis City in groups of 2 before finally engaging the boss. The Infiltration stage requires stealth to avoid patrolling droids and a certain amount of group coordination.
Infiltration
To start the Infiltration, click the panel near the door to Oasis city. The timer starts as soon as you click the panel so do not click until you have prepped your raid for what is about to happen.
There is a time limit on getting to the Operations Chief. On storymode, this is 10 minutes. Note that this is 10 minutes from the moment you clicked on the panel to start the infiltration to the second until you engage the Operations Chief. The timer ends as soon you attack Operations Chief.
Your raid must divide into 4 groups, each with two players (on 8m). Groups with combinations of tank/DPS or healer/DPS work the best as the tank/healer can either heal through or eat the damage. You cannot do this part with more than 2 players per location (on 8m) as the mobs you need to attack have a buff that triggers the alarm if there are more than two players attacking them.
Each group need to be assigned a position on the map (Blue, Gold, Green, Red) and move to that location. Locations further up north such as Blue/Gold may be best for groups composed of stealthers as there are some patrolling Battledroids that are hard to avoid. Operative/Scoundrel group stealth works great for this encounter.
Each location have an unique combination of mobs
Red
Flametech and Assault Gunner
Green
Duelist and Pyroguard
Gold
Medtech and Pygoguard
Blue
2x Hunter
Mobs at Blue and Green hit hard. Healer + DPS is recommended.
At Green, you can have a range dps attack the pair of mobs below the stairs, this prevent you getting aggro from the patrolling battledroid on the stairs.
Tanks + DPS works fine for Red and Gold
Oasis Enforcer Battledroids patrol the city. These guys are Champion level mobs with around 170k HP. If killed, these guys will respawn almost immediately so there is little sense in killing them. Avoid detection if possible but if you do aggro one of the battledroids, you can CC them and they will disappear once you engage the Operations Chief. Note that there are warzone health pick up things scattered around the map if you are low on health and dont have a healer with you.
Once all 4 groups are in place, Kill the two NPC corresponding to each team and make your way to the Operations Chief up in the north. These NPCs cannoe be crowd controlled but can be stunned.
Classes like Operatives can go use their group stealth to help everyone get past Battledroids that are hard to avoid.
Operations Chief
Operations Chief is a fairly straightforward boss but he does have some nasty tricks up his sleeve.
Terminate
Terminate a 3 second cast with massive single target damage that will most likely one shot anyone not a tank. Make sure no one pulls aggro in the beginning or they risk getting one shotted by the boss. Tanks will need to use defensive cooldowns to survive through this attack if they are low on health.
Mass Explosive Probe
This is an Explosive Probe he throws on the entire raid that explodes if the person with it takes damage or if the timer (25s) ticks down to 0. It deals around 7.5k damage but most of it can be absorbed by sorcerer/sage bubbles.
Rail Turrets
A group of four Rail Turrets spawn around the room. These guys have around 19k HP and die fairly easily.
Aggro Drop
Operations Chief seems to have an aggro drop whenever he hunker down and knockback the tanks.
