Yes, I'm sure "?%" was correct. —The preceding unsigned comment was added by Danmcfoo (talk · contr).

Updated coordinates. Edit

The header only lists one set of coordinates. There are 4 distinct, never moving, places where they spawn. Since someone doesn't want the info added to the main article, I'll put it here so maybe it will help someone.

There are 4 places where they spawn, all in Blade's Edge Mountains.

  1. [27.42, 68.55]
  2. [31.77, 63.80]
  3. [33.42, 51.83]
  4. [28.80, 46.50]

There are 6 mobs at each spawn point.
