Omega Red vs Morningstar AQ boss

I don't understand i have 1 point invested in coagulate yet my 4/55 Omega red was taking bleed damage when fighting MS boss in AQ, shouldn't he be fully bleed immune?
is this a bug?

I think he is fully poison immune and 90% bleed immune when he awaken

hmmm thats not how maths work

if you are to take 100 bleed damage omega ignores 90 of it and take 10

with 1 point in coagulate you ignore 10% of that remaining 10 bleed damage and you take 9 bleed damage instead

so its not 90% from omegas immunity + another %10 from coagulate

I believe it’s similar to other masteries in the way it’s factored. Coagulate says you will take 10% less damage from bleed. If your champ took 100% of her bleed damage, then you would see the 10% less benefit. But since Omega already takes 90% less, he’s only taking a 10% damage, so coagulate is only giving him 10% of the 10% damage he’s taking for a whopping 1%, hence you don’t notice the difference.

And MS has enhanced bleed which is figured in AFTER the 90%. So you will take around 200 bleed damage with OR depending on PI
