We have a whole thread of testing in the pokemon topic
but the tldr takeaway is spearwoman is #1 option now
holy freeze + cursed already amps the packs of immunes and heralds you need amp against. You already fry isolated bosses with tainted, where aura fails to proc amp at all (0% not 5%, it doesn't hit them only attacks do)
spearwoman deals more dps from more attacks than normal mob, venom lord deals less dps from fewer attacks than normal mob, siren deals vastly reduced ranged dps, flayer shaman doesn't attack at all
steps are:
find 8 player cursed TZ game (baal runs can work)
apply act 5 shard
search frigid highlands, frozen river, ancients way, worldstone keep 1 for spearwomen
if you find a zone with them, teleport around and prespawn them all to lock in the P8 stats before anyone can leave the game
find only the white trash mob spearwomen, not minions/champions/uniques
bind them one by one with +19 skills gear on, so you have level 20+ bind demon after +skills
if a bound demon isn't holy freeze, teleport away before it can kill other monsters and unsummon it
you're done when you get a holy freeze spearwoman
Thanks for the explanation, I managed to get myself one but only in single player, I will keep an eye out for full cursed games and try again.
The hardest thing was keeping them alive whilst trying to bind them before the merc killed them but I guess that won't be a problem in p8.
Cheers
