A new boss monster?

[magpie]

I just came across a new boss monster, a unique will o'wisp - I forget its name, and I don't know what it does that's so special (since it was one-shot), but it's interesting to note anyway. Has anyone else seen it before? Does anyone know what it does?

That might be the boss monster I made. Was it called Aksarnerk?

No, it had a weird name and it was blue-coloured, not yellow.
