Damage Auras and Damage Procs

Okay, I've got a question. I'm tinkering around with my build for my Titan/Elec brute, and I've got very little experience in dealing with Lightning Field or other damage auras. What I'm wondering is, how do damage procs like Eradication, Obliteration, Scirroco's Dervish, etc. work in a damage aura? Are they an effective way of boosting the aura's damage? And for that matter, how do Interface procs work out with damage auras?

All procs, now, have one chance to proc every ten seconds in any type of toggle or rain power, damage auras included. For the proc to happen, the relevant tic has to hit and the proc has to succeed as well, similar to any other attack. Opinion varies, and of course it depends on what sort of character you're building, but for something like TW/ELA I absolutely feel that at least one proc in the aura is nice to have. I don't know the exact DPS value of a proc compared to damage slotting but my feeling is that having the proc built into six slotted oblit is a nice bonus, and if you're frankenslotting the aura then four slots of damage, accuracy and endurance enhancement are nicely topped off by the proc of your choice.

Normal Procs (Chance) go off about every 10s after turning on.

Intercafe unsure on the Proc rate might be same as Normal Procs.

From my understanding of Procs and Interface its basically the same thing.

"Since Procs work when the power is activated, then they continuously work when slotted in a Passive Power or in a Toggle that's turned on. Procs that are in continuous powers cycle or pulse on once every 10 seconds. This is also true when they work in certain pseudopets like 'rains' or 'patches' that have an enduring effect. If slotted in a click power, Procs activate just once for the duration of their effect.
Most Procs have an effect that is immediate (like the chance to damage Procs) or last a few seconds (like the mez Procs). Some Procs that provide a self buff have a duration of 120 seconds and will last a full two minutes past when the power is clicked.
Procs which affect targets have a chance of activating for each target the power 'hits.' This makes Procs slotted in area of effect powers very beneficial; more so if it's a continuous area of effect like rains and patches.
Procs that have a chance to do damage, do so based on the level of the character and not the level of the Proc. The damage is not modified by ArcheType. See Table of Proc Damage for specifics." http://paragonwiki.com/wiki/Proc#Procs

So would there be any real advantage to slotting in both, say, Eradication and Scirroco's Dervish damage procs into a PBAoE or damage aura?

If a PBAoE Click (Burn, etc) it will give a Advantage since it will check when used. Toggles Maybe.

What about Lightning Field?

Well to me, Lighting Field is more Mini-Control due to -End about every 4s, 'I' would slot for Endmod and EndRedux(1 or 2) and maybe one Dmg Proc. Preemptive Interface for -End in attacks and a 2nd chance for -End in LF +more NrgDmg. and Agility Alpha for EndMod = Melee Sapper.

Lighting Field Toggle PBAoE -End
Power Sink (depending on slotting) about every 20-25s.
-End Interface -End for all attacks even if Non-Ele melee.

To me EleArmor is Strong in two ways, high Res and never without End.

Damage procs--both from Enhancements as well as Interface--will trigger every 10 seconds beginning with the activation of a persistent power like a damage aura. The instant you toggle on, the first proc is rolled, then every 10 seconds after that.

Having two procs in lightning field has an additive effect in the same way that having two performance shifter procs in two different passives does. You won't be able to always count on one of them happening but they will both deliver their full effect without any regard for the diminishing returns you get from enhancing the damage of the power. If you can get 95% damage enhancement into lightning field in four slots, in other words, adding the first proc will be just as beneficial as adding the second proc to the last two slots.

Most of the auras tick every 2 seconds, so every 5th tick has a chance to proc, so you have a 20% chance every 5 ticks, which is roughly comparable to a 4% chance per tick. You can sort of abuse this a bit by arranging to turn the power on during a fight (guaranteeing an instant check of procs), but since damage toggles tend to have a noticeable activation time that's not as useful as it might seem.

So it's not awful, but it's not as good as it could be. Caltrops can be a bit better just because you're activating it all the time, so you get a lot of first ticks. (Also, out of 45 seconds you get 5 checks, so it's a very slightly better average.)

That's one way to look at it seebs, but the way I see it is that on a meleer, well, if I'm not surrounded by dudes most of the time I am doing something wrong. Thus, a damage aura is an attractive place to put at least one proc since it doesn't require any animation time on your part to frequently dish out a bit of bonus damage.

Everything everone else said, but as far as optimizing damage auras for damage and at what point would one be over slotting procs and cutting into basic acc/dam? Thats a toughy, at least for me. I was thinking about it and in general one would take several things into consideratoin.

1. Chance to proc of the proc and its dam
2. Final to-hit of the aura (cant proc if it doesnt hit)
3. The long term average of however many procs you have
4. Saturation of your aura
5. All of the aura slotting options

I would start by adding up the damage generated by the procs, adding up the likelihood they would proc and dertermine an average damage/10sec multiplied by your acc bonus for the aura. Example: if you have two procs slotted and each have a 10% chance to do 100 dam and you acc is 95% then I *think* the average damage output would be 200 x (0.10 x2) x 0.95 every 10 sec. Having both procs hit the same in a given role would be 0.10 x 0.10 every 10sec. I'd think after 3 procs your going to really interfering with the inherent damage, but I wouldnt trust me to do such a convoluted calculation.

I enjoy adding procs to damage auras. Usually slot 2-3 acc/dam HamiOs and 3-4 procs. The following is a copy and paste of my Damage Inflicted screen of my Spines/DA scrapper in a +2/x8 AE mission. He has 10 damage procs spread between 3 auras. I edited all the "Notion Scout looks fearful as your Cloak of Fear takes hold," and, "Notion Scout reels as your Oppressive Gloom overwhelms them," just to make the post shorter. All the proc damage are marked with the word "bonus" in the line and a smiley face. Everything listed below happened within 2 seconds, the end to the start of an Oppressive Gloom cycle. Of course it only looks like this every 10 seconds but always manages to put a grin on my face when I do see it:

Geez that is delicious. That is just from procs in quills and death shroud? What Interface do you use?

What do you have in Quills?

While we're asking questions, about the once/10 sec rule: is this once every 10 seconds once the power is on, or is it a universal 10s that has to do w/ the server?

In other words, if I toggle one damage aura, wait 5 seconds, then toggle another damage aura (each w/ damage procs, of course), will I have a chance to proc every 5 seconds, or does the server check every 10s, and if I'm using a damage aura, applies the chance to proc?
