Malygos tips: Phase 3 strategy

Ok, so we need to greatly improve our performance in Phase 3 of the Malygos fight. Here are some tips.

First off, the drake abilities that you should be concerned with are as follows:

Key 1 - Flame Spike (costs 10 energy, awards one combo point): This is your offensive combo point builder. It's a regular flame ability that does a relatively small amount of damage.
Key 2 - Engulf in Flames (costs 50 energy and combo points): This is your offensive finisher, meaning it costs both energy and combo points to use. It will place a powerful DoT on the target that will last longer the more combo points you've used (6 seconds from one point, 10 from two, 14 from three, etc). Note the high energy cost and the fact that it takes time for the flame to "reach" the target in order to actually apply a stack. This will be the primary source of our damage.
Key 3 - Revivify (costs 10 energy, awards one combo point on the healed target (not Malygos)): This is your HoT. It stacks up to five times on yourself, replenishes 500 health per second per stack, and it lasts 10 seconds. In other words, if you have five stacks on yourself, it will heal you for 2500 health per second. If you have combo points on Malygos and then use this ability, you will lose those combo points because you've "changed targets" (to yourself) and used a combo point-generating ability. Welcome to wonderful world of rogues.
Key 5 - Flame Shield (costs 25 energy and combo points): This is your defensive finisher. It puts a shield around you that reduces damage taken by 80%. It lasts longer the more combo points you've used (one will yield two seconds of the shield, five will yield six seconds).

The drake has 100 total energy, and it regenerates at a rate of 10 energy/sec. The global cooldown on the drake's abilities is one second. The primary goal here is to manage your energy effectively. You can't just sit there spamming your '1' and '2' all the time; you'll be bottomed out on energy and will probably die very quickly. Here's a rotation that seemed to work well in our 10-man Malygos kill:

Make sure that your "Auto Self Cast" is turned ON in your Interface -> Combat options. This will make your '3' automatically cast the heal on yourself just by pressing the button (instead of having to then click on yourself).
When you land on your drake, hit '3' a few times while you get yourself into position. Target Malygos, and always keep him targeted.
After you've hit your last '3', immediately hit your '1' four times, which will place four combo points on Malygos.
Wait for your HoT to tick down to 2 or 3 seconds remaining or until your energy caps out (if you sit there at max energy, you're losing out on potential regen time), then hit '2'.
Refresh your HoT at the last second by hitting '3'. I usually hit my 3 just when my buff timer ticks to "0s"; if you have lag, you might want to do it a hair earlier just to be safe. Just remember, the earlier you refresh it, the less energy you will have regenerated during that "round" of your rotation.
Go back to step 3, rinse and repeat.

-- SURGE --
In the event that you get targeted for the Surge of Power, chances are you'll be sitting with at least one combo point on Malygos (and probably four) that you've built up. If not, quickly build one to three points by using '1'.
Hit your '5' right when he starts casting the Surge (don't do it early). Immediately refresh your HoT by hitting '3'. Immediately hit '1' three times, then hit '2' once you have the energy. Refresh your HoT again by hitting '3'.
Get back into your standard rotation by going back to step 3, keeping in mind that you have less time this rotation to get your 4-point Engulf back up.

When you get the Surge on you, it does disrupt your rotation for sure. The key is to stay alive and not let your DoT drop. Without everyone's stacking double-digit DoTs on Malygos, we won't get him down before the enrage. If your HoT drops, so be it. Just work it back up slowly by executing the standard rotation. Again, you cannot let the DoT drop. Period.

A sound rotation, good energy management, and the ability to adapt to how the Surge disrupts your rotation will lead to success on this. You should all practice on the Aces High daily quest in Coldarra. It helps a ton.

There is a strategy that involves assigning certain people as healing drakes, but if we all execute this well, there should be no need for that. We'll see how things go.
