Less than 2 hours later. Naturally, it's In-game hours.
West of Riverdale Town and South East of Black Mountain Town was the the level 0 map Stone Creek forest. Though it was called a level 0 map, it didn't mean that all the monsters here were level 0. The rating of a resource map was based on the weakest monsters present and also the recommended level for players. A level 0 map would now mean a map where the lowest level of a monster would be 0 and also players at level 0 would have a chance to live. If it was a level 5 map, it would mean that the lowest level of a monster would be level 5 and players aren't recommended to go there unless they are at least level 5.
