Vexie Fullthrottle Raid Guide in Liberation of Undermine

• Place Oil Slick puddles away from the group.
• Attack the bikers once they are nearby.
• Hop into bikes that are left behind and aim them at the boss to remove stacks of Protective Plating.
• If you are targeted by Incendiary Fire move away from pools that you spawn and do not run into any Oil Slicks.
• Tanks: Swap after one stack of Tank Buster.
• Once all stacks of Protective Plating are removed the intermission phase will begin.

• Interrupt or CC the Pit Mechanics and prevent them from casting Repair.
• DPS: You don't need to focus any damage into the Pit Mechanics. They will die from passive cleave damage if they are under the boss.
• Avoid Burning Shrapnel.
• Any remaining Pit Mechanics will disappear when the intermission ends.

• After The Geargrinder has been destroyed kill Vexie to finish the fight.

In this phase your goal is to remove all stacks of Protective Plating before the boss reaches 100 energy. These stacks are removed by riding bikes into the boss.

• Geargrind Bikers:
  1. These spawn after Call Bikers is cast. These bikers will charge at players (nearby players prioritised) and stop when they hit a wall. Try to bait these near the boss so you can efficiently cleave them down.
  2. Once you kill the biker you can take control of the bike by clicking on it.
  3. Aim the bike at the boss by rotating your character and use Blaze of Glory (Vehicle button 1) to ride the bike into the boss and remove a stack of Protective Plating.

A player using Blaze of Glory on the boss to remove a stack of Protective Plating

• Spew Oil is cast on several players and they will have a purple ring placed around them. These players need to run away from the group and place these in locations you do not intend to use. A good place to put them is against the edge of the room.

• If you are inside of an Oil Slick you will slide across the ground, take ticking damage and be slowed.
• Tanks: The tank mechanic on this encounter is aptly named Tank Buster. This is a simple 1 stack swap mechanic.
• Healers: After Tank Buster the boss will apply Exhaust Fumes to the entire raid. This damage is not very threatening but adds up.
• Healers: Several players can be targeted by Bomb Voyage! during this phase. These players will require some targeted healing.
• Once all stacks of Protective Plating are removed the intermission phase will begin.
• If The Geargrinder reaches 100 Energy it will begin casting Unrelenting CAR-nage. You will have a short amount of time to send a final bike into the boss before you are overwhelmed by the damage and wipe.

During this phase the boss will take 100% increased damage for up to 45 seconds!

• Pit Mechanics will continually spawn during this phase and attempt to channel Repair into the boss. Each second they channel this removes a second from this phase. You can interrupt the cast or CC them. Tools such as Death Grip to bring them under the boss and Leg Sweep to AoE stun them are great.
• DPS: You don't need to focus any damage into the Pit Mechanics. They will die from passive cleave damage if they are under the boss.
• Burning Shrapnel pools will continually spawn during this phase. Avoid them.
• Healers: The boss will continually channel Backfire dealing raid wide damage.
• Any remaining Pit Mechanics will disappear when the intermission ends.

• After The Geargrinder has been destroyed kill Vexie to finish the fight.

• Phase 1: Tank Buster leaves behind an Oil Slick requiring you to move the boss after each cast.
• Phase 1: Oil Slick will stun bikers if they ride over it.

Currently, this tab will only contain information on what changes on Mythic. A more robust strategy will be added after the raid goes live.

• Oil Canisters now appear when a biker has been defeated. They will create a puddle that needs to be soaked and applies Soaked in Oil to that player. Any puddle not soaked will spawn an Oil Slick.
• Two Oil Canisters are required to fuel a bike so it can be used to charge into the boss.
• Support Rig now spawn during the intermission making Pit Mechanics within 15 yards immune to crowed control.
