Arms Warrior DPS Liberation of Undermine Raid Guide — The War Within (11.1.5)

• There are no particular Spell Reflection mechanics, so use it as a general defensive cooldown.

• The first single target burn should happen around 1:45 into the fight, so feel free to use cooldowns on the pull, but save the second use of Avatar.

• Interrupting Repair is crucial to prolong the intermission!

• There are no particular Spell Reflection mechanics, so use it as a general defensive cooldown.

• The first Colossal Clash occurs around 1:20 into the fight, so Avatar can be used 5-10 seconds before the pull to better line up with each phase.
• Colossus has better two-target cleave, though Colossal Clash only lasts 20 seconds, which is not long enough to make up the difference from just playing Slayer with Improved Sweeping Strikes instead of Bloodborne.

• Flarendo requires high movement to avoid various mechanics, which is typically easy for melee damage dealers.
• Torq requires much more careful movement to avoid getting stunned, though Charge, Heroic Leap, and Intervene can all help.

• There are no particular Spell Reflection mechanics, so use it as a general defensive cooldown.

• There are no adds on normal difficulty, so treat it as a full single target encounter.
• On Heroic and Mythic difficulty, a set of Pyrotechnic barrels spawns with each Sparkblast Ignition, so time Bladestorm and other cooldowns accordingly. You will not have cooldowns for every set, though Anger Management will allow you to get most of them.
• Avatar can be used around 6 seconds before the pull to line up better with later sets, at the cost of single target damage on the opener.
• If for some reason adds remain a problem, consider swapping to Colossus instead, though boss damage will be reduced as a result.

• Scrap Rockets can be deflected with Spell Reflection.

• There are a lot of periodic adds throughout the fight, though they take extra damage if picked up first by Rolling Rubbish. If your group is coordinated enough to pull this off, try using Bladestorm then.
• Colossus may be preferred for more add damage on Mythic difficulty, depending on how well controlled the adds are.

• There are no particular Spell Reflection mechanics, so use it as a general defensive cooldown.

• Use on cooldown, as long as you will maintain uptime on the boss.

• The encounter features high movement, but is otherwise pure single target with generally very high uptime. Slayer is recommended, but be extra careful of the inability to move while channeling Demolish if choosing to play Colossus.

• Electric Blast can be deflected with Spell Reflection if it happens to target you.

• Time cooldowns with Spin To Win! as much as possible, since the extra targets adds need to die very quickly.
• Depending on which combination of tokens are deposited, players may have to deal with a large group of bomblets that are perfect for Bladestorm.

• Because the adds are frequently spread out, it can be hard to hit more than one at a time, so stick with the full single target build and rely on Sweeping Strikes instead of Cleave.
• Staying close to the blue Pay-Line beams can get you the High Roller! buff, increasing damage by 10% for 15 seconds after the coin rolls by, just make sure it does not hit you.

• There are no particular Spell Reflection mechanics, so use it as a general defensive cooldown.

• Despite limited opportunity for cleave, this is a very single target oriented fight with a major Execute phase.
• Sweeping Strikes will cover most of the adds that spawn while on the left side of the room, and should be timed for Volunteer Rocketeer spawns in particular, since they start in Execute range. Sweeping these Executes onto the boss will allow players to not only deal a lot of extra damage, but also pre-stack Juggernaut.

• The boss goes into a burn phase at 40%, which is perfect for Execute and Juggernaut.

• There are no particular Spell Reflection mechanics, so use it as a general defensive cooldown.
• This fight has a large emphasis on moving to avoid damage, so there are not a whole lot of places where cooldowns are necessary, unless you will not be able to avoid a mechanic in time.

• The majority of the Normal and Heroic fight is single target, with predictable set of adds each time the boss reaches 100 energy. During the following intermission, when the boss has moved to the edge of the room, there will also be two cleavable adds which Sweeping Strikes is perfect for.
• On Mythic difficulty, there will instead be much more periodic groups of short lived adds spawning, so consider dropping Bloodborne for Cleave.
• The newly buffed Wrecking Throw can be used to deal a gigantic amount of damage to the Armageddon-class Plating absorption shield, though because it is only used once throughout the fight, it is unlikely to contribute enough overall damage to be worth the extra talent points, and therefore should only be done if struggling to break the shield on time.

• The biggest part of the fight is moving quickly, to both avoid or accomplish certain mechanics, so Charge, Intervene, and Heroic Leap are all very useful for getting where you need to be as quickly as possible.
