Leveling

There are two ways to level up in this game.

Leveling Room

First leveling approach is through Leveling Room, this room consists of 3 floors and it has 3 NPCs and those are Job Changer, Monster Summoner and Floor Warper. You can find the Leveling Room NPC in the middle of the Prontera Main Town. Monster Summoner NPC only summons up to 10 monsters and each monster you kill will instantly level you up regardless of your level. Floor Warper can help you warp to the next floor or warp you out to the main town. Job Changer can help you choose what Job Class you want

Dungeons

Second leveling approach is through classic dungeon leveling, you can use @warp or Warper NPC to go any dungeons you want, if the Leveling Room is Crowded then Dungeons is the best way to level up. You can find any Warper NPC in any major towns.
