There is a massive list of monsters to kill for this achievement. Are these rare monster spawns completely random in the world or are there set locations that I should look? If so, has anyone compiled a list?

[Side note: I noticed this achievement when my buddy got it in Co-OP and I did not - As I was not by him at the time. Be sure to be near your co-op buddy when you down the rare]

Yes. These monsters only appear in certain areas, but they are not guaranteed to appear every time.

Most of the otherwise non-randomoverworld has this - non-random terrain, with randomization variables; monsters and dungeons that may or may not appear.

  • Are specific monsters only in specific acts?

    Yup. I'd recommend one of the wikis for a "who's who". Commented May 17, 2012 at 18:09
