Encounter Notes for Liberation of Undermine
Table of Contents
My personal encounter notes. Some of this is generic in regards to e.g. intermission timers and cooldown decisions so others may also find it helpful.
Note that these are updated as we progress through Mythic. Unless it has a dedicated Mythic section, everything is for Heroic!

There's a lot of damage happening here, so having a defensive script greatly helped. Thanks to Vollmer for creating it.
You can use this as MRT note with the Kaze MRT TTS aura or TimelineReminders. Obviously replace Xephyris with your character name.
 Zephyr is likely assigned by your raid leader, we have it during each intermission.

Devastation

 Dragonrage every first set of adds on pull/after intermission Dragonrage every first set of adds on pull/after intermission

- full send. you'll lust on pull anyway and first cd window will cover first set of adds largely. fight, especially early on, is very hectic so better to get used to timers

 Zephyr Zephyr Trash Compactor at ~1:20 Trash Compactor at ~1:20- after that, can be used for  Electromagnetic Sorting which should occur nearly identically to add spawn waves from above Electromagnetic Sorting which should occur nearly identically to add spawn waves from above

Devastation
- unless you care about padding on adds, you just use  Dragonrage on cooldown, so far it never conflicts with Dragonrage on cooldown, so far it never conflicts with Rolling Rubbish or Rolling Rubbish or Overdrive Overdrive
Augmentation
- likely identical to Devastation, full send
- good chances this fight sucks big time for Aug if you're unlucky and your current buff targets get picked for  Rolling Rubbish Rolling Rubbish

 Bleeding Edge intermissions are at Bleeding Edge intermissions are at- ~02:05
- ~04:30
- note that these are heroic, possibly different timers on normal/mythic
 
- debuff overlaps of  Sonic Ba-Boom and Sonic Ba-Boom and Unstable Explosion hurt Unstable Explosion hurt- this is probably nearly entirely avoidable with correct timing of  Product Deployment triggers but be prepared for these while learning the fight Product Deployment triggers but be prepared for these while learning the fight
- very good value for  Renewing Blaze Renewing Blaze
 
- this is probably nearly entirely avoidable with correct timing of 
 Obsidian Scales your assignments of Obsidian Scales your assignments of Product Deployment Product Deployment- due to  Unstable Shrapnel you need to reserve one charge only once every 2 minutes so you can liberally use the other Unstable Shrapnel you need to reserve one charge only once every 2 minutes so you can liberally use the other
 
- due to 
 Zephyr has good value on both Zephyr has good value on both Sonic Ba-Boom and Sonic Ba-Boom and Voidsplosion but the latter only occurs during the intermission Voidsplosion but the latter only occurs during the intermission- can likely use on pull for first  Sonic Ba-Boom , then both intermissions Sonic Ba-Boom , then both intermissions
 
- can likely use on pull for first 
Devastation
 Dragonrage on pull Dragonrage on pull
- and then either during or after each intermission- if the second is after intermission, say 2:30, then next is at ~4:55
- if the second is during intermission, say 2:20, then next is at ~4:45
- so either way, not a large difference that would allow you to get another one in
- imo very awkward for 2 minutes. the reason you're not sending on cooldown is that on intermission start, the boss jumps away and also knocks the entire raid to the opposite side of the room, so you're out of range for a considerable time
 
Augmentation
 Breath of Eons on pull Breath of Eons on pull
- same pattern as Devastation. adjust based on buff target cds
One-Armed Bandit
- Reel Assistant add sets spawn at 0:20 and then every 60 seconds thereafter

- 0:37 (+32)
- 1:09 (+32)
- 1:41 (+32)
- 2:13 (+32)
- ... you get the idea. it's one before each set of adds and one during or after if you're fast
 
- very important (some might say BIS) WA playing Kaching! when you're buffed by  High Roller High Roller- you can easily have high uptime of this, watch out for it
 
 Flame and Coin has most value for Flame and Coin has most value for Zephyr Zephyr- since it depends on the combo, can't set a timer for this
 
 Electric Blast , Electric Blast , Coin Magnet and any overlap of Coin Magnet and any overlap of Pay Line with Pay Line with Foul Exhaust are good Foul Exhaust are good Renewing Blaze cases so kinda send whenever Renewing Blaze cases so kinda send whenever
Devastation
- assignments to pick up coins may influence your timings, so these suggestions are based on the assumption that you have no assignments at the given time
- make sure you have empowers for each add set, or at the very least,  Mass Disintegrate Mass Disintegrate
 Dragonrage on pull Dragonrage on pull- note there's a first  High Roller window at ~0:10 High Roller window at ~0:10
- also note that it only lasts 15s so barely into adds. obviously still a gain during cds so watch out
 
- note there's a first 
- hold  Dragonrage for 30% of the boss if close to it and/or played through the combos Dragonrage for 30% of the boss if close to it and/or played through the combos- this should be around 4:30 on Heroic at least
 
Augmentation
 Breath of Eons on pull and on cd except for holding one for phase 2 Breath of Eons on pull and on cd except for holding one for phase 2- breathing the adds is probably only useful on Mythic
- they're the damage check but the priority targets will very most likely die before breath pops, so you'd only get in some cleave and boss isn't focused
 
Mug'Zee, Heads of Security
- primary damage taken is, like on Cauldron, passive damage via  Elemental Calamity and Elemental Calamity and Uncontrolled Burn Uncontrolled Burn- miraculously,  Renewing Blaze syncs with the side swaps every minute so this is largely a send-on-cd angle Renewing Blaze syncs with the side swaps every minute so this is largely a send-on-cd angle

 Dragonrage on pull Dragonrage on pull- and on cd pretty much. on Mythic you likely want to hold at some point for Intermission / P2

lmao respec :skull:
in all seriousness, the only thing you want to watch out for is not to  Breath of Eons briefly before

likely full send with a possible hold for intermission. not worth holding for adds outside of maybe Mythic
