I'm not exactly sure about this. I'll need some confirmation from those who play kSRO or cSRO. I just recall someone saying that in Chi'in tomb, you have to collect keys in order to open other areas.
Are these keys dropped by the uniques in the tomb?
Do these opened areas have uniques in them?
Do you have to do this repeatedly in order to reach Medusa?
If the answers to all of these is yes, then that's pretty much a dungeon system. Is it an
instance? I'm not quite sure. If the player/party is the only one who can be in the tomb, then it's an instance. But again, I need confirmation from kSRO/cSRO players. Do you get to choose if you want to do an instance or not?
This also brings me to kSRO's Legend VIII where it's not much of a huge update compared to other Legends. They just added a handful of uniques and a small new map. In this Legend, as I heard, you have to kill these four harpy-looking uniques to summon Roc. Again, it sounds a lot like an instance, although this time, it's some kind of a keep instead of a dungeon.
Does kSRO/cSRO have such a system? I'm really curious. If Silkroad does have it, that's great news because this game is finally getting some end game content.
Maybe I'm just getting my hopes up for nothing.
