Help updating Chaos Bolt Prediction WeakAura?

[Atonement 0]

 

Hello everyone! I'm a huge fan of weakauras, and developed for myself a weakauras-based Destruction rotation suggester and cooldown helper that is almost 100% accurate. Currently I have it disable itself if Dark Soul is active, so that I can make the decision of what to cast for myself, even though the Chaos Bolt proc tracker I have now is pretty effective.

 

What it looks like at a full-ember state: http://i.imgur.com/0fcwAag.jpg

 

One further way I could improve this would be to implement a working chaos bolt prediction function that would output a number as text. You can see toward the right of my character that there is a random "0.05M" sitting there, sort of hidden in the snow. This is from a function that I found here on this forum after a google search at: https://www.icy-veins.com/forums/topic/4932-weakauras-burning-ember-bar/?p=66509

function()

local crit = GetSpellCritChance(6)

local spell = GetSpellBonusDamage(6)

local mastery = GetMasteryEffect(6)

local pre = (2488+(2.5875*spell))*(1+mastery/100)*(1+crit/100)*2.09*1.05

return math.floor(pre/10000)/100

end

 

 

 

 

But of course this is no longer an accurate formula for Chaos Bolt's damage, and I've never messed with these numbers before. Could anyone help me update this to a 6.0.3 state? If I could, and I could output that number, I could use it to give the rotation suggester a certain amount of intelligence with Chaos Bolt suggestion, even during procs and Dark Soul. 

 

Of course this isn't something I actually NEED; I think I know to Chaos Bolt with 2 trinket procs and Dark Soul ready, but tracking the relative power of an upcoming Chaos Bolt relative to the possible maximum power (something I could obtain quickly each time I do a new combat test with new gear simply by looking at what the prediction outputs during a situation with all procs + potions + dark soul) would allow me to create perhaps a color overlay or a progress bar depicting how relatively powerful a chaos bolt would be before I even fire it! How cool would that be?!

 

To do so would be simple if I could just get an accurate prediction. Right now that function DOES work in that it outputs a number (that isn't THAT far off) but it's definitely outdated because it's still wrong by at least 50% every time, doesn't account for multistrikes, etc...

 

If I can get this working I'll happily post pastebin links for the entire WeakAuras setup!

Hi!

 

After finding this thread I decided to try to get this WeakAura to work properly.

My findings is that the formula below works almost perfectly for me (off by 1-3 dmg) and is tested with buffs to crit, mastery and versatility. I read in changelogs that Chaos Bolt had been buffed by 8% and that is where the figure 1.07957 comes from.

 

Please respond if you find this to be incorrect for you.

 

 

function ()

    local school = 6

    local crit = GetSpellCritChance(school)

    local mastery, _ = GetMasteryEffect()

    local spellpower = GetSpellBonusDamage(school)

    local versatility = GetCombatRatingBonus(29)

    local pre = (1+(2.1075*spellpower)*1.07957)*(1+crit/100)*(1+mastery/100)*(1+versatility/100)*2

    return math.floor(pre)

end
