Core Mechanics
Rain of Arrows functions by resetting its cooldown constantly through
Preparation. We use
Heartseeker with
Shard of Verathiel and
Crown of Lucion for that purpose.
With
Crown of Lucion fully Stacked and
Elixir of Resourcefulness every
Heartseeker spends 62 Energy, which means we want a total of 186 Maximum Energy to cast 3
Heartseeker in a row seemlessly. This is perfect to enable
Precision.
Concealment
Once we cast
Rain of Arrows we need to get back our Energy.
Concealment with
Tibault's Will generates 140 and
Skyhunter generates 60 for a total of 200, more than the 186 we need.
Runes
We use
Ahu +
Zan to Overpower for [x]50% more damage when it's up.
We use
Zan +
Qax to make use of the massive damage multiplier it provides.
We use
Igni +
Mot for
Dark Shroud in the Mythic Variant.
Elixirs and Incenses
It's important to run Elixirs and Incenses at all times. Not only because they increase our Experience gain but also because they provide very strong combat boosts.
For Elixirs, we will use
Elixir of Resourcefulness for Resource Cost Reduction and Maximum Resource.
For Incenses, we will use
Queen's Supreme for Dexterity,
Reddamine Buzz for Maximum Life and
Soothing Spices for All Resistances and Armor.
Cooldown Reduction
You can use THIS Sheet to calculate your Rain of Arrows Cooldown by making a Copy. We need the cooldown to be 10 seconds.
Attack Speed Breakpoints
Because the game's server operates in frames (images), Skills can only be cast in a whole number of frames. This means, for example, that you can't cast a Skill in 10.2 frames. To extend this example further, that means that all Attack Speed values that lead to a cast time of 10.01 to 10.99 frames would mean you end up casting at 11 frames, effectively wasting all Attack Speed gains from 11 frames to 10.01.
In order to avoid wasting Attack Speed, you can calculate the Attack Speed Breakpoints for your skills using THIS SHEET.
You might be wondering how frames translate into actual Cast Speed. Because the server runs at 60 frames per second the way we translate frames into Cast Speed is with the formula: 60 / Frames = Casts per Second.
