BUG? Unable to corrupt Enduring Composure small cluster with Corrupted Blood Immunity

I've been corrupting Enduring Composure Armor Small Cluster Jewels and after some research, it seems none exist in Crucible League or Standard.

Is this a bug?

I see other +Armor Small Clusters with Dragon Hunter, Militarism, Uncompromising, Stubborn Student, etc... but zero with Enduring Composure.

Why is this? Very unfortunate if this is a undocumented "feature" or bug, as I've spent quite a lot of time trying to make my own this league as a key component of my build.

this isn't a bug.

this is a mix of RNG and people simply not vaaling these jewels.

armour cluster jewels are not frequently used by the majority, so few ppl are crafting them to vaal, hell quite a few players aren't even picking them up.

also there is only one armour cluster CB jewel with stubborn student, 0 heart of iron, 0 prismatic carapace, 0 battle hardened, 1 militarism, 1 second skin, 1 dragon hunter, 1 blacksmith, 3 uncompromising.

secondly 2 exist in standard with enduring composure and CB immunity on armour% clusters...

You are correct, now see 2x on Standard.

It must be extremely rare.


Zero in Crucible and the 2 on standard were not there when I checked for 2 days.

Thanks for your inputs.

I personally have Vaal'd many, many Enduring Composure jewels and never hit Corrupted Blood.
