Having convection helps a lot with the chance to hit, but I agree that that's going to make cursed very challenging to apply. I'm of the mind to try a couple of things. One might be to lean into the physical aspects and run a act 5 mercenary with a dreadfang, and then have the demon run fanat. The loss of conviction is big, but the heavy physical will help offset that. Another is to lean the opposite and just have the amp happen if it does, and not worry too much about it. Outside of A5, it seems that most jobs with physical immunity have very low hp, which neuters some of the need for constant amp.
well its 50%ish block on bosses with nothing around to trigger amp off aura. You can also self-wield infinity, but then we're comparing -85 on infinity to +30/-30 on a facet sword to +5 skills / +5 / -20 on mang songs, and all those -resists on facets/song aren't nerfed vs immunes like infinity
Another option would be to pack a hel'd non-upgraded gavel of pain and use it exclusively against fire immune heralds.
Keep in mind its just the difference of 4.8k per blood boil in any of these cases. If you have 8100 / -55 fire and 4800 phys on blood boil, then against fire immune / 50% dr monsters you'll deal 8.6k without amp, 13.4k with amp (down from ~15.2k with amp+sigil before sigil became a non-functional skill). The amp is always just going to add that 100% of the base phys value. If heralds are 50% dr fire immune mobs an amp from whatever source will be 1.56x overall dps, while if they were 0% dr fire immune its 11k without amp, 15.8k with, so 1.44x.
Tainted build can even go further, because if you summon all 3 tainted and lose the +20/-15 on blood boil and on top of not having amp (sans gavel), so you could be doing 6.8k to the 50dr/fi or 9.2k to the 0dr/fi, but the tainted themselves can deal 23-30k hp after -resists per 22 fpa volley
of course the 2x tainted + defiler does more dps if there are multiple targets, like heralds have, because then you're multiplying both blood boil and tainted shots, and same thing for blood boil, but more relevantly it matters for the bound demon physical dps. And against immunes when a max bound demon build can have ~25k damage entering with swap gear and get that 56% splash onto 4 targets, THAT winds up being a huge dps source with as much as 50k per swing before defiler, compared to tainted struggling to damage immunes for their 10k per fireball
But its still a tricky thing to assemble. Your urdar needs stone skin to survive heralds now, preferably an act 5 urdar so its unbreakable 125% dr phys immune vs amp damage, which is worth the lost regen/speed. It won't be poison immune unlike other options like venom lord who can be immune to
everything (well except magic, or amp/curse/conviction). And spearwomen can't be phys immune even with stone skin, they cap out at 99% dr funnily enough, granted a stone skin spearwoman should still be mostly unkillable even by heralds. But now that she doesn't apply amp reliable to bosses, eh, you're reduced to that "do I gavel?" I think however that would ONLY apply to bosses, because she'll still amp herald packs with her aura.
farming cursed + stone skin uniques and having only a tiny % to roll the right aura is tough enough especially if it still takes some playercount to reach the max HP (I don't know), and the build can't even get super uniques until level
99, though that mostly matters for trying to farm infector of souls for a venom lord setup
and the fact that for anything but the urdar, you're at serious risk of some cursed mob just deleting your demon instantly, after all that setup, even when its phys immune? eh
