How do interface procs work with dots?

Was curious how these effects worked with attacks that hit a target multiple times per activation, like DP's hail of bullets and bullet rain: because of their "DoT" nature, can each tick of damage apply an individual debuff, or is it just once for the entire attack?

While reactive is a no-brainer, diamagnetic's +100% chance of -tohit (available at T3)would be a killer soloing tool if I could get it to stack quick enough... it lists as -5% per application and can stack up to four times, although I'm unaware of how long the debuff lasts for.

Also, is the -regen portion of this ability (if I chose the 100% -tohit/ -50% -regen) useful at all outside of AV/GM battles? T4s have been hard for me to come by, so if it isn't a big deal it would be one less thing I'd need to worry about... for a while anyway!

I can't say for sure on the DoT question since I haven't tested it myself. However I would guess, based on how other procs work, that an attack being DoT or not wouldn't make any difference. IO procs, for instance, have one chance to go off per click no matter if the attack is a DoT, and I would think interface procs would work the same way. Best way to stack quickly then would be to just fire away with AoEs as fast as possible.

As for the regen question, though, I can tell you it'd be completely useless. The regen debuff is only 15%. The problem with that is that minions, LTs, and bosses regenerate health slowly enough that debuffing it doesn't really matter, while EBs/AVs/etc that actually regen enough that you might want to debuff it will completely ignore such a tiny debuff since they resist it so heavily.

For example, even a level 54 boss regenerates only ~6 HP per second. Debuffing that by 60% brings them down to ~2.3 HP/s, a difference of a paltry ~3.5 HP/s. That's basically nothing. On the other hand, a level 54 AV regenerates just over 100 HP/s, however its resistance to -regen debuffs reduces that 60% debuff to under 8%, and you end up debuffing them for a paltry (again) ~8 HP/s. Even if you can reliably quad stack the proc, it's just not worth it.

Thanks for the response, I'll have to craft it and experiment when I get home. I think that being able to stack -20% defense from a single attack seems a bit overpowered, but again I'm not sure on how reactive interacts with DoTs (a DoT from a set like DPs anyways).

I'll research it firsthand later tommorow and see what the results are.

for most DoTs it checks once at the beginning of a power (for example the dark power gloom which is a pure DoT will only check upon first hit)

for patch type powers and toggle powers it does a proc check once every 10 seconds

now for specifically the power in question i am not totally sure how procs go into it, but im fairly confidant it will not check on every tick

it will either:

  • [A]proc once for each enemy
    [B]proc using the 10 second rule of patches/auras

would have to test some to actually see what will happen

Proc's in power, whether procs from IO's or from incarnate powers, make a check to go off then the power is activated or makes an attack roll. Usually this is the same thing, so in almost all cases you are going to get 1 check for the interface proc.

Offensive toggle powers and psuedo pet powers are a special case. Offensive toggles are either only activated once at all and/or make multiple attack rolls every few seconds so if they worked as a normal attack procs would never fire off for the offensive toggles that are auto hit or don't actually make attack rolls (like acrtic air) or they would fire off way to often for toggles that tick every couple of seconds (all damage aura's). So there is special coding so that these check for proc activation every 10 seconds (as well as once on initial activation of the toggle/psuedo pet)

Psuedo pets such as Rain of Fire, Sleet or freezing rain are another special case and are often confused with DoT's as they appear to have multiple ticks just like a DoT. However, a true DoT such as gloom only makes one attack roll and RoF and its kin make an attack roll for each DoT. So the same code used by toggles was enabled for psuedo pets to make sure they only checked for proc firing on the first attack and then once every 10 seconds after that. There was a period of time after the last 4 incarnate slots where released when psuedo pets and toggles fired off the interface proc on every single attack roll, which made them insane, but that was fixed a while ago.

Just verified what Eric had posted, yeah it's only one app per "DoT" (as in hail of bullets, gloom etc), and one check per 10 seconds on damage auras. Regardless of this, diamagnetic is helping me out big time solo now; malta are now no longer a -guaranteed- death sentence on my corr (although I'm timid about going over +4 spawns without having the T4 clarion unlocked).

Thanks for helping me get to the bottom of this guys.
