the Zoal the Ever-Wakeful set effect should have the visual effect of animated watcher tentacles.
However, it currently seems to be broken, only a tiny part of them appears, and they remain completely motionless.
I equipped the skeleton polymorph for better visibility, as without it the effect can be hidden by armour:

If I'm correct, I think the tentacles are stuck on the first frame of animation, and never emerge from the character's back.
I understand this is a minor issue, but I think it's a shame that such an amazing looking animation is bugged.
For reference, here is the picture of how it should look:
