on fire-immune tier5 herald packs (especially ppl8) - has anyone tried just immediately summoning 2 Defilers over 2 Tainteds?
Wouldnt the shared damage from 2 defilers likely let your bound demon clear the mobs faster than the ~22% fire damage from Tainteds?
this is assuming your bind demon is 20 hard points (and 40+ lvl overall), so it deals a ton of damage with cursed (+spearwoman jab)
The idea being that boosting the demons output with defilers is better on fire-immunes than the Tainteds nerfed dmg
You can definitely deal more dps to the fire immune heralds with demon+2x defilers while spamming blood boil, but it slows you down overall since you'd want to resummon tainted by returning to town and prebuffing, which takes longer. They just don't take that long to kill anyway. You can see it in the numbers. Say its a pack of 50% dr fire immunes. 2x Tainted hit about 3-5 at a time for ~16k hp every 22 fpa (4x ~18.2k dps = 72.8k). Blood boil just from the physical portion can be hitting all 15 of them for ~7.7k at 9 fpa after amp (15x 21.4k dps = 321k). A spearwoman might hit one target for 75k at whatever random speed, about 18ish fpa on average I'd guess. (1x ~104k dps = 104k)
Defilers spread about 1.57x on 5 targets for 7.85x (+285%) since it doesn't shotgun with multiple instances, just one +57% per blood boil to the 4 extra targets in the chain, and one other target sharing its 57% back to the one that hit the other 4
If its spreading its full benefit by a lancer hitting extra 4 defiler targets and blood boil hitting all 10, that raises total AOE of blood boil from 321k -> 443k, and lancer from 104k -> 341k
Which of course is far more than what you're losing in 2x tainted here.
That should all be pretty unsurprising, tainted are extremely nerfed against fire immunes, and their damage against non-immunes is so astronomical it just one-shots them so the main limitation is moving around fast enough, while a bound demon has gigantic dps but melee range and single target attacks that limit her from being able to apply it to anything but a big damage sponge. So a big damage sponge herald that is immune to fire winds up being a prime target for blood boil + lancer, and could take a lot of extra dps, and you can get about 80% more overall DPS by summoning 2x defilers in the best case
Except as I said above, this is pretty pointless. If it took 10 seconds to kill a fire immune herald without that +80% dps, maybe it takes 5.5 seconds instead. But its going to take you more than 4.5 seconds to go to town, swap your gear, resummon tainted, swap back. When you already have the huge demon + blood boil dps, the defilers just aren't really worth the effort.
