Blackflame + ignite resistant rare

So it appear those new mod make ignite impossible with blackflame ring.

That's because Fire and Ignite Resistant monsters have +75% to Fire Resistance
and 80% reduced Ignite Duration on you. Blackflame has another 50% reduced Ignite Duration on Enemies, so ignites just don't apply.

I guess they'll nerf these "resistant" mods in future. For now you can try to overcome the reductions with "#% increased Ignite Duration on Enemies" mods.

Just getting back to you, this is intended.
MonaHuna has explained what's happening here.

This sounds like a regression to a previous change made to this interaction.

In Archnemesis league, patch 3.17.2, the Incendiary Archnemesis monster's ignite resistance effect was changed from reduced duration to less duration, referencing "an issue where characters with the Blackflame Unique Ring equipped were unable to Ignite monsters with this Archnemesis modifier."

It might be worth taking another look at with that context.

In case nothing changes though, I believe it is possible for Blackflame users to ignite these monsters with Unbound Ailments Support socketed.
