~ Average population I'd say is 50.
~ The event to get hero gears is held monthly yes. But those are not our only custom, some have quests (npc) others drop from monsters.
~ ToH event has no level requirement, yet I would not recomend entering becore 80ish, by that time 350k shouldnt be too much of a problem. Don't get discourage if you don't win at your first ToH, just consider it practice.
~ WoE are nice imho, we have 4 castles, 3 open to everyone, 1 only for non-trans and old ro classes it's a good place to start.
~ Reset master charges 10k per level after 40 for one reset (stat or skill) or 15k for both stat and skill + asks you an item after level 50. After level 40 it can get costy fast. Reset should not be done lightly!
