[Mage] Rolling Ignites: are they back?

manly · 01/08/08, 6:41 PM

As maybe some of you are aware, there has been a few reports here and there about 'rolling ignites' that existed since TBC came out. There is even one small mention on wowwiki about this, basically saying that it seems to occur when you crit every 2 seconds.

Up until now, this is about as much as has ever been said about the inconsistent 'bug' that has been observed a few times.

Well, I made a theory of my own that would explain the 'bug'. And exactly how to reproduce it. Before I get there, let me explain the basics so that I avoid silly questions:

The damage dealt by a spell is calculated upon a spellcast, and not upon a spell landing. This is the very reason that shatter-combos exists.

What if the ignite damage was also calculated upon a spellcast, and not upon the spell landing ?

Think about it for a second. If my theory is true, it would effectively explain why 'rolling ignites' have been observed in the past. Here is how it would go:

-> T+0: Your fireball lands and crits for 1000 dmg.
-> T+2: Ignite deals 200 dmg.
-> T+3.95: You finish casting a new fireball. (1dmg crit + 200 dmg left for ignites)
-> T+4: Ignite deals 200 dmg.
-> T+4.05: Your new fireball lands and crits for 1 dmg.
-> T+6.05: Ignite deals 100 dmg.
-> T+8.05: Ignite deals 100 dmg.
(note: yes I am aware this is more like rolling 'half' an ignite. But still, you get 600dmg from your ignite rather than 400)

In other words, my theory is that you can 'roll' an ignite if you get an ignite tick while your fireball (crit) is traveling. This is not really much different than using the travel time of frostbolt in order to get a shatter combo. Please note that by adjusting your distance from your target, or rather, increasing the travel time of your fireballs, you could achieve/reproduce this with more ease since you would not need as much haste rating.

Keep in mind, nothing has been tested. This is pure theorycraft, so it might be wildly off-base. I created a new thread because it would be fairly hard to follow within the other mage threads.

In order to get 2s fireballs, you need:
-> With Icy Veins: 2 = 3 / (1 + x) / 1.2 => 392 spell haste ratings
-> With Bloodlust: 2 = 3 / (1 + x) / 1.3 => 241 spell haste ratings

Now keep in mind, [Drums of Battle] and [The Skull of Gul'dan] can fix most of your spell haste ratings needed for Icy Veins. There are many gear compositions that can be made in order to achieve those spell haste ratings.

I openly invite any mage to try it out and reproduce this. Let's see if we can abuse Icy Veins.

EDIT: There is a case where I am not too sure what would happen. If you land a crit during your first ignite tick. I assume you would effectively end up with the same result, but proper testing needs to be done.

It's not a problem for ignite to tick for 2k+ if you crit with fire spells a few times in a row fast enough. But if you crit within 100-200ms of eachother it's as the first spells ignite will be counted for (5x combustion and fireball+fireblast is a easy way of repeating this).
Is something like this you're looking for?

Whats really interesting is if a crit refreshes the duration of ignite damage cycle or it just adds it to the next tic. From what I have experience it just adds it to the next tic which is rather nice for the flow of the ignite damage (and I wish once and for all they just remove the stupid fireball debuff). I can find more things like this in the logs easily where ignite starts at 800 after a fireball and grows up to 1800-2000 after a few consecutive crits and ticks every 2 seconds still with each individual point, 800, 1125, 1310, 1640 etc unless I am hallucinating.

No that is just a normal ignite adding up together, what I am talking about is specifically getting more than 40% extra damage from your ignites through proper timing of your fireballs (ie: 2 seconds fireballs).

Grecasi · 01/08/08, 7:59 PM

Yeah, my bad really. Though I was looking at something here and it seems rather interesting.

Counting 3x fireballs for crits, should yield normally 12 second or 6 ignite tics so to speak. Critting 3 times in a row seems to shorten the duration of the debuff from 12 to 10 seconds. Logs I'm showing are a bit off though, since the first ignite starts ticing 2.5 seconds after the first fireball crits (server has been a bit lagged lately with up to 20-30 min queues).
So we condense the same damage in shorter time which is a dps increase, in this case 10 seconds vs 12 it would have done if they would have been left seperate?
Sorry if this if offtopic, won't have IV until tomorrow morning as I play in Europe.

edit: it's actually just 2 crits in a row that will condense it optimally, from 4 tics to 3. 2 crits then a normal hit then 2 crits hit would produce 6 ignite tics where there should have been 8 in 4 seconds faster time.

In the TC thread i tested this twice and twice i've shown indeed that if you do have 2 second fireballs it does work pre-BC rolling ignites.

Edit (2.3.2 PTR testing):

Xei · 01/08/08, 8:24 PM

2 second fireballs is achievable with just a well timed Berserking along with Icy Veins.

Not every mage is a troll though, and half the time, you end up with a 10-15% Berserking instead of an intended 30% you want.

Finkum · 01/09/08, 12:41 AM

For testing purposes, rather than gathering a non-trivial amount of spell-haste gear/buff items, couldn't you simply follow a fireball with a fireblast (waiting for ~2s to simulate the cast time of a hasted fireball)? Obviously the cooldown on fireblast means you can't just spam it every 2 seconds to get a continuous rolling ignite, but presumably a single roll is all that is required to decide the issue either way.

I think the problem with fireblast is that it doesn't have a travel time. But you could test it with a low rank of fireball (= 2sek cast) i think.

If my theory is correct, then yes, exactly as you said, the travel time is an absolute necessity.

The good news is that this can easily be tested using a G15 to do 2 scorch spam.

Yes and yes, but there are plenty of boss fights where the whole raid takes X damage which brings you substantially down in life.

Bloodlust is 30% haste, IV is 20% and Berserking is 10-30%.

Bloodlusted FB == 3/1.3 = 2.3s

IV FB = 3/1.2 = 2.5s

Berserking FB = 2.73s-2.3s

In order to get 2s fireballs, you need:
-> With Icy Veins: 2 = 3 / (1 + x) / 1.2 => 392 spell haste rating
-> With Bloodlust: 2 = 3 / (1 + x) / 1.3 => 241 spell haste rating

Berserking: I'll have to do some testing to confirm, because I do not really trust WoWhead comments as accurate - but it states that you get the full 30% haste at 40%hps or lower.

So assuming 30% haste @ 40% hps.

Also assuming berskering scales linearlly between 100% and 40%hps (confirm/deny?)

So each %hp below 100 is worth 0.5% haste (30(haste)/60(hps)).

Drums+Skull = 255 haste rating.

STACKING BERSERKING WITH IV

At full hps, 10% haste.
2 = 3 / (1 + x) / 1.2 / 1.1 => 13.64% haste * 15.76 => 215 haste rating

At 40% hps, 30% haste.
3 / 1.2 / 1.3 = 1.92s ... you are there.

With zero passive haste equipped you need to get 13.64% haste from berserking, so 72.72% hp.

STACKING BERSERKING WITH BLOODLUST

At full hps, 10% haste.
2 = 3 / (1 + x) / 1.3 / 1.1 => 4.9% haste * 15.76 => 78 haste rating

At 40% hps, 30% haste.
3 / 1.3 / 1.3 = 1.78s ... you are there.

With zero passive haste equipped you need to get 4.9% haste from berserking, so 90.2% hp.

So at full hps (assuming no passive haste), you could essentially Drums+Skull+IV+Berserking for 10s of rolling ignites on top of the crazy damage you can put out in the 30s of extreme haste.

Then when bloodlust is popped, Drums+Berserking for 10s then skull for another 20s to get 30s of rolling ignites ... in execute range with Flamecap+Combustion.

So what us Trolls want to do when BL is popped in execute range:

1) IV for 20s.

2) Berserk at less then 90% hp for 10s, or Berserk+Drums at full hp.

3) Drums+Skull for the rest of bloodlust.

manly · 01/09/08, 1:15 AM

as per the formulas I provided, all spell haste ratings are additive, but cast time modifiers are multiplicative (ie: bloodlust/icy veins/berserking/focus).

example:
1% passive spell haste rating
30% = bloodlust
20% = icy veins
cast_time = 3 / (1 + 0.01) / 1.3 / 1.2 = 1.90s

In other words, bloodlust + icy veins + no spell haste gear is probably too much haste already.

Using Rank3 Fireball that is a 2 second cast time.

1/8 22:30:18.968  Your Fireball hits Dr. Boom for 270 Fire damage.
1/8 22:30:21.004  Your Fireball crits Dr. Boom for 409 Fire damage.
1/8 22:30:21.427  Dr. Boom is afflicted by Ignite.
1/8 22:30:23.023  Your Fireball crits Dr. Boom for 418 Fire damage.
1/8 22:30:23.023  Dr. Boom suffers 82 Fire damage from your Ignite.
1/8 22:30:25.223  Your Fireball hits Dr. Boom for 270 Fire damage.
1/8 22:30:25.429  Dr. Boom suffers 166 Fire damage from your Ignite.
1/8 22:30:27.291  Your Fireball hits Dr. Boom for 276 Fire damage.
1/8 22:30:27.499  Dr. Boom suffers 165 Fire damage from your Ignite.
1/8 22:30:27.791  Ignite fades from Dr. Boom.

Crits for 409 and 418, 2.019 seconds apart
Total damage is 827
Expected total ignite damage is 330.8
Observed tota ignite damage is 413
Extra Observed Damage = 82.2

It appears that the first ignite is giving us our normal damage, but then it get's rolled into the new ignite. Free 20% damage?

Xei · 01/09/08, 2:05 AM

Hmm, this is sounding too good - can anyone find a flaw with my math?

Clearly, the solution is reach 100% crit rate and spam rank 3 fireballs since post-TBC ignite are uncapped

Just to clarify; you do not want your fireballs to cast much faster than 2s -- if my theory holds then you might end up having to wait (ie: no dps), or adjust your travel time by being further to the boss.
