Hi,
Please check both fortress instances as they are not giving rewards (no way to exchange dungeon leader badge, another one does not decrease pk count). I've check on small and large fortresses - the same.
T.y.
Achieving clan lv. 5, according to description, grants you the ability to have a fortress, however fortress NPC says, that you need lvl 6. Is that a kind-of-typo ar a bug?
enchanting is just an expensive hobby if you don't make money out of that. so if you don't own a char with appropriate build, just don't do that. buy in the market.
I could imagine many various measures to be taken by admins to fight the problem. but putting server cap that resulted in 200+ queue ??? c'mon, what year is that?
Yes, can confirm that scrolls isn't a problem - you can farm a lot. But crystals are not worth to farm with current drop rate, despite any boosts you may use. Guess, they will appear in l2store one day.
