Is it Viable?
My Fire Armor Brute just hit 50 and I've been playing around with IO builds and I got this idea, that instead of just slotting an entire Oblit set into Blazing Aura, what if I put in the 4 Chance-on-it for Damage IO's from the 4 different PBAoE Damage sets that have them. I Figured that with a Blazing Aura DoT hitting so frequently 4 IO's with 20% Proc chance for around 71 Damage (107 on Armageddon's) would out weigh flat damage increase and the Set Bonus.
Now I thought this was a good enough idea that I went to the forums to look at some posted builds to see if this is what people actually do for DoT auras and I saw that no one, at least that I looked at, did.
Which brings me to my question, does this work the way I think it does? Is there a reason people don't do this? Does having multiple procs in one power not work or do Procs in DoT Auras not work at all? etc.
Procs in DoT auras get one chance to go off every 10 seconds, not on every tick of the aura. So a 20% chance to deal 71 damage on every fifth tick is basically ~3 damage per tick when you average it over time. This is roughly comparable to slotting a damage SO for most auras (including Blazing Aura), so auras aren't strictly a bad place to put procs, but they're not particularly better than regular slotting either (until the ED limit, anway), and you don't get accuracy nor cost reduction nor set bonuses from filling a power with procs.
