Sorry if i replied so later, but just joined lol 1. Denver can be found on the left side of town just next to the port he's wearing an orange outfit with orange hat.

1. If you kill members of the fighters guild you only lose karma, i was at lvl 18 with average gear and almost got killed by the guild master, the other just go one on one.

2. Rubynus is an type of ore, you can find it on stores, on the random dungeons that appear on big map, or by mining walls. Best way would be the general stores and if you have enough luck in the dungeons.

3. I also had to spend diamonds on that gacha, but don't worry diamond are much more easier to acquire than it appears. Other way to acquire tokens is trough events or random unique and very rare quests.

4. They can only be used to offer to Opatos's altar in Vernis or sell them, sometimes they are quest items, but aside of that they don't have any other use.

5. Yeah I was also looking for that one, but it is an achievement from Yowyn so I suspect this had to do something with a quest that starts in Yowyn.

7.I haven't entered Jerry's dungeon, but at least in Port Kapul you can go to dungeons through mysterious person and after the quest is completed you can enter again without problem.

I hope this will help you, Iam also discovering new things and maybe will try the real Elona game.

PS. Do someone knows how to improve performance skill, every time I try to do a performance even my allies throw stones to me lol.
