The following are the best Locations and Dungeons in the World Map of Lineage 2 Revolution to farm. While there is an auto-combat function in Lineage 2: Revolution, it is not active while the character is logged out. Players should ensure that their devices have sufficient power when attempting to farm for long periods.
In general, a suitable monster to hunt repeatedly (farming/grinding) is one that is near your level, you can defeat safely and carries drops that can help you progress further or improve your stats. It is highly recommended that the target monster is close to your character's level; experience awarded per kill drops off rapidly if your character is 4 or more levels higher than the level of the monster.
In Lineage 2: Revolution, Monster Cores, Quest Scrolls, Proofs of Blood and Red Starstone are most commonly sought after. The first two items are materials for improving your character. Monster Cores are required for completing entries in the Monster Codex, granting bonus stats for each entry. Quest Scrolls allow you to complete additional sub-quests, and are a decent source of experience points and Adena. The other two items, Proof of Blood and Red Starstone, are clan resources that are required for upgrading various (if not all) clan functions.
