So essentially tainted would be like your golast skill in the 90s after everything else is maxed. Now that lethargy has been turned into trash tier it's not like there's a whole lot worth using the final points on. With enough bonus skills you should have a good tainted minion anyway. I'd rather not handicap the bloodboil or demon part of the build. An urdar with fanatacism/curse and might aura is going to slap bosses around. Plus you can continue casting bloodboil on bosses with an urdar due to the high regeneration rate. If you pick a low hp regen demon bosses become that much more difficult (due to lack of corpses). I'm still in the process of shopping for another urdar in river of flame they're so good on bloodboil builds it's hilarious. Now that I think about the amp nerf I wonder if lightning enchanted will allow it to proc enough to be another option aside from holyfreeze.
Well hard on skill points. 60 for boil engorge oath for max damage. 20 demonic mastery 15 bind demon to be able to have 3x demons and bind uniques. You could get away with 1 bind demon if you only used the TZ cursed method, you'll never get stone skin / lightning enchanted / multiple shots. But even a basic level 1 venom lord could hit max hp and have decent amp spread with holy freeze + inferno, his damage would be gimped anyway
But then you don't have the demon slots. 1 defiler is just worth more than 1 tainted, the impact is so huge. 2nd defiler is often redundant though. But then you have a bound demon and consume. So what do you trade? You could skip bind demon. 20 tainted, 2x tainted and 1 defiler.
So the upsides are 2x heavy dps tainted and you never lose a hard to replace demon and can tank with demons freely and even do bosses like baal / ubers without any risk because you just resummon. And more single target dps, and summon 3rd demon vs single bosses. What you lose is +20% fire, 15% pierce, 32% life, 43% frw, amplify damage, some super high physical hits on demon when it connects, and its reliable melee tanking
I think there might be merit to the max tainted build. Losing some serious fire damage on blood boil if you don't consume, but you COULD consume for mob clearing and summon 3x tainted for bosses. And skip bound demon entirely. No amp, it would hurt. I doubt a self wield infinity + dreadfang merc would outperform mang songs + infinity merc though.
Current blood boil build has 8.1k fire / 4.8k phys, -100 amp, -37 sigil, -55 pierce, -85 conviction.
Say enemy has 33dr/33fr, it does 25.8k per hit. Against 50 dr / fire immune its 15.2k.
PTR you lose sigil dr. So against 33dr/33fr it does 24.2k. Against 50 dr / fire immune its 13.4k
Now say you also lose the consume bonus. fire drops from 8100 to 7200, pierce by 15, so 33 fr becomes -92 instead of -100, immunes become 38% instead of 23%. And lose the amp AND sigil.
So no consume PTR against 33dr/33fr it does 17.0k per hit. Against 50 dr / fire immune it does just 6.9k
Point being- if you skip amp merc, you lose a big chunk of damage and huge gimp vs immunes. If you skip consume, you lose a big chunk of damage vs everything. You lose 1/3 your dps to non immunes, 1/2 to immunes. Big sacrifices and even if you consume 1 tainted, you still lose that amp which matters a lot vs immunes.
