If you're tired of having to wait for Syrillax to finish flying and want to have faster runs this guide is for you. Please keep in mind that this will not work 100% of the time because of how random procs and Syrillax are.

Gear Recommendations
First, lets start off with what you need, you're going to need a strong team with decent gear. Here are some recommendations for each class:

If you are a mage, having at least a death engine staff and lvl 71 or 76 arcane armor is preferred.

If you are a rogue having at least death engine daggers and lvl 76 arcane armor is preferred.

For warrior, having at least lvl 76 arcane armor and whatever lvl 76 arcane weapon is better is preferred (I'm not that familiar with warrior).

If you are soloing, having both level 76 arcane weapons and hotbar is preferred

Mechanics
How Syrillax works is that she performs her attacks in a sequence. She does basic attacks for the first 3 attacks and 5th attack. On the 4th attack, she performs a small wind-up attack. On the 6th, she performs a big wind-up attack. While she is flying, she will drop 6 ice crystals before coming back down, attacking then doing a big wind-up .

Method 1
Step zero (optional): If you have both weapons, equip your buff weapon first (this would be your staff or dagger)

Step one: Do not attack until Syrillax has finished performing 4th or 3rd attack.

Step two: Use buff ultimate if you're using it (Energize, Refuel, Rage) and go all out

Step three: Hope that all your procs are active during 6th attack wind-up

Step four: Use damage ultimate if you're using it and have all your buff procs up (Meteor Strike or Ultimate Aimed Shot).

Step five (optional): If you have have both weapons, equip your damage weapon (gun or bow) and keep going all out until dead

Method 2
Step zero: Make Syrillax fly

Step one (optional): If you have both weapons, equip your buff weapon first (this would be your staff or dagger)

Step 2: Do not attack until Syrillax drops 5th ice crystal. Try not to get stunned

Step 3: Use buff ultimate if you're using it (Energize, Refuel, Rage) and go all out on mobs and hope for procs

Step 4: Wait for Syrillax to land

Step 5: Go all out once Syrillax charges wind-up. Use your damage ultimate (Meteor Strike or Ultimate Aimed Shot). If you have both weapons, equip damage weapon (gun or bow).
