[STICKY] Post-Chaos Training Spot Guide
As for the rest of the Level 110+ section, now that Lionheart Castle is out of the way:
-DGPs are still great until 115, if you can't go to LHC yet. MDTs are still decent as well.
-At level 140 or so, you can go to the Temple of Time. From Leafre, which you can fly to from Orbis, just go to the top of the station and talk to the dragonmaster. Fly all the way right to get to the ToT. There's a lot of boring quests available here, but they give decent EXP despite their monotony. The EXP is worse than LHC and there's a ton of hackers, but at least you can loot Pieces of Time which can sell for a decent amount. This map is often overrun by hackers and botters aiming for PoTs, so getting a free channel might be difficult. Depends on server. (Note: Fairly crowded map)
Level 30 to 120:
-PvP. Talk to Maximus in most towns to get to Battle Square. This will be monotonous and slow, but it's one way to get to 120. It can also give you good equips. Better when you're in the higher area of your level bracket (i.e. level 60 to 70, 110 to 120, etc etc)
These are all the people who've helped me refine this guide and correct misinformation so far. Some helped more than others, but they all contributed in their own fashion. This guide would not be here were it not for these users, so many thanks to all these guys.
