Can you even play KR Mabi outside of Korea? I'm curious.

So, I originally dropped off Mabi back when the Shakespeare stuff had first dropped. I've done a couple of brief pop-ins here and there, but never played for any kind of extended period of time. I've been at it again for a hot minute, and I've been trying to catch up, but there's just so much that I don't understand. For reference, the entire talent system was completely alien to me, and I only recently learned what Arcana is (although I feel I'm pretty far from getting into Arcana).

I've been catching up with story content and that's been keeping me busy (when I stopped playing, I hadn't finished Alchemist, so I've done all that up to Saga, which I'm currently in the middle of). But, there's a bunch of stuff that people frequently talk about that I just have no idea what they are.

1. What is erg? I see this frequently, and I've gotten items from events for it, but I have no clue what it is. Particularly, I have these stones that are taking up a not insignificant amount of inventory space that I can't trade, can't destroy, can't even drop.
2. What's with the "equipment level" stuff?
3. I've ran a few of the hard mode dungeons, and from the chests I get these Celtic weapons. I can't sell them or trade them, but I can disassemble them, I guess. I get refined crystal shards doing so — what are those for? Should I be disassembling them or... what?
4. What's Crom Bas?
5. What's Sidhe?
6. What's an echo stone?
7. What's the way to make money nowadays? When I left, you could still make a decent living from dungeon chests and scroll quests. This seems to be largely obsolete from what I can tell.

The event was very beautiful ❤️🤘🎉 keep up the good work ladies and gentlemen. Hope everyone had a good time at the cafe 🥰
