Ailment threshold of bosses

hi guys,
is there any info on ailment threshold of bosses? the pinnacle bosses on poedb have the field empty but also their health values are way downscale from what you actually face. i wanna do some ignite dps calculations but i have no way to start, if you cant have any idea on chance to ignite.

its 20% of the hit damage, scaled by your ignite magnitude. so if you have 50% extra ignite magnitude thats 30% damage per second over 4 seconds.

the chance to hit is 1% per 4% of base ailment threshold (basically: bigger hits more ignite chance). someone wrote you cant exceed 25% chance though.

the short of it is: its hard to ignite enemies unless you use abilities with big hits (e.g. flameblast) or you use sure forms ignite such as demon dog or solar orb.

now technically my flameblast does about 20k dps (practically i do about 50k per cast, i need 1.17s per 10 stage cast but i have no clue why unless my numbers are super wrong. hard to tell without training dummy) and im trying to see if its worth it to change skill points to make ignite be permanent up. because you can gain around 50% ignite magnitude quite easily. lets say 100% with gems. so at that point you do 40% of your hit damage per second. there is another node which changes the tick rate to 0.85, so you would do 47% per second.

what that practically means is, if you get a 100% uptime of ignite you would technically (assuming uninterupted chain casting) add 56% dps but practically, as you cant repeatedly cast add probably around 80% of your dps on top of your casts.

so thats why i need to know the ailment threshold because its quite hard to trial and error pinnacle bosses to see if i can actually ignite them with flameblast or not.

i see ty. i had another thread asking about this to see which form of ignote would be most efficient but this is going to be pain to figure out. you speak of pinnacle bosses- how about regular bosses? can you get perma ignite on them? just curious how this scale with mob hp, as in does the igniting hit(s) has to be so big that ignite damage is not practical or is it viable?

i have no idea thats what im trying to figure out myself. the info isnt out yet. i learned today that in general its based on max health but if a map boss has like 2 million hp that would mean you need to do like 500k damage do get a 25% chance without modifiers and thats very impractical. so for very high health targets i think there is a modifier we dont know about.

I would assume they have ailment thresholds that are different from their hitpoints, as was the care in PoE1.
Also, there'll always be some chance of triggering an ailement, it'll just be weak and inconsequential.
Until this is either datamined, or an official statement made, I doubt we'll be able to find out everything (or enough to make informed decisions).
