Several Jobs tend to lose a lot of MP due to Lost Action usage. Lost Cure II will help them avoid out of mana situation whilst being inflicted with Slow+, a stackable slow debuff. This can be easily negated if you're geared with at least +3 Haste from God Save the Queen content.
The slow does not affect your overall DPS per boss kill, nor should you lose personal DPS. Instead it can be considered as a raid utility that benefit the alliance. Mages can use Font of Magic's full duration with MP Refresh on them and Healers using Seraph Strike can get their MP back quickly.
Potency of Lost Slash is tripled when it lands a critical hit. MCH's Assembled buff does that trick nicely. Considering how often you can use it with Assembled, that is a nice push in your DPS burst.
Ranged classes can consider Lost Font of Power as a general DPS Action.
Banner of Noble Ends increases your damage by 50% but makes you un-healable and thus, Noble Ends would require to be timed outside of raid wides to ensure that healers are able to heal you up.
Banner of Honored Sacrifice drains your HP whilst increasing damage by 55%, it is manageable damage and you can bring a Resistance Potion to help with the heal.
Note: Timing it badly without valors may lead to death (especially during hard hitting raid wides)
Banner of Noble Ends should be timed outside raid wides and generally is the safer option since you can click the buff off if you require heals.
Banner of Honored Sacrifice can be considered if you have Resistance Potion just in case, or you have Valors of Fortitude / Valors of Succor (self-heal) to ensure your survival.
That's actually a simple solution. Stop FULLY, cast Lost Perception, wait 1-2 seconds, repeat this step until you find the trap. Interestingly there are areas where you can stand safely to scan for the trap. These safe locations are fixed.
As you can see, the location in Slimes and Golems area are fixed. So essentially you're scanning only 3 locations before proceeding. This also applies to the corridor between Boss #1 to Dahu and Phantom to Boss #3. (Boss #3 being extremely important to find 2 special traps)
Team A should keep Lost Perception until after Dahu. At the end of the first boss, there are a total of 6 traps to identify.
Team D may bring along a spare Lost Perception. Use as much charges on Lost Dervish as possible and finish it by the end of Phantom. Once Phantom ends, swap Dervish with Lost Perception to scan area to the third boss.
The rest of the Ranged should switch out their Secondary Action. The next time a Ranged will swap action will be for Minotaur and B4 for Lost Dispel.
Ideally, You should pre-cast Dervish just 2-3s before the fight and keep it on cooldown.
If you have 2 Ranged players in a party, You can rotate to keep dervish uptime. Communicate with your party member to see who goes first. Macro helps too!
That's because Lost Dispel is a spell and not an instant GCD.
Err, no that's not how it works. If you're assigned to bring it, you should have in active in your Duty Action. What if all the Dispel Ranged are dead and you're the only one alive? We need every Ranged to be vigilant on their Dispel duty as un-dispelled buff will wipe the alliances, especially in Minotaur and Queen!
Just one. It's impossible to finish using up the charges in a single lockout. Do note that Lost Dispel is just as important as Lost Dervish. At this point, you should be in Minotaur fight, which means both your essential actions are: Lost Dervish & Lost Dispel.
