Suggested Farm #3: Travel North out of Tsumei Village to Lake Puang. During the 2-minute walk, you will encounter about 15 low-level naga in groups of 2-3.
Threats & recommended skills
Threats:Naga Wizards have Teinai's Prison @ 5 Water Magic. Unless you are using a character that is not yet level 20, no other real threats exist, as the Naga do not do enough damage to pose a threat.
Tactics: important tactics, for example pulling, choke points etc
Recommended skills: Bring attacks or spells that are affected by armor. Since the Naga are no higher than level 6, some high-powered attacks or spells can kill in one hit.
Suggested Solo #1: Run to Raiyan Cave from Tsumei Village and clear out the cave. On the way there, some of the Kappa will aggro, but you can avoid all groups on the way there, or run past them since they are not a threat. Any melee build works. Elementalists and Ritualists should spam direct-damage spells. Other caster professions can use SoS Spirit Spam.
