According to the Monster Book, it notes that Evil Eyes spawn in Tree Dungeon: Forest Up North (without the Roman numerals). There are 9 tree dungeons there and none of them have Evil Eyes. Don't know if it's wrong spawn setting or wrong Monster Book information. There is one actually called Tree Dungeon: Forest Up North (without the Roman numerals), when according to bbb, supposed to be VIII(8), but there are only Curse Eyes in there. Edit: Well. I need to change the title. There are no Evil Eyes in Swampy Land in a Deep Forest, Hunting Ground in The Deep Forest I & II too. So, basically only appear inside the Ant Tunnel.
I think its some typo mistake. If im not wrong all LHC mobs is at oblivion v map according to the monster book (not sure its fixed or not but i remember that). When it come to mobs location just use bbb. Btw i believe reporting typo thread here https://royals.ms/forum/threads/typo-text-error-reporting-thread.121610/
Devs might had done some mob adjustments, so online databases may not always be correct either. For example, the Pig Park. Didn't know there's that thread. But, I saw one typo(or rather lacking a space) that I could check right now, which was reported back in 2019, is not fixed yet though.. Looks like they aren't monitoring that thread anymore?
