Kanturu Event

The event's entrance is in Kanturu Ruins at 141,186, and you need a Moonstone Pendant to pass. The pendant is found in Kanturu Ruins and is worn in a ring slot. It cannot be traded but can be dropped, and once you are inside the boss map you may take it off. Up to 15 players can take part at once.

• Kill all 50 monsters to make Maya's Left Hand appear, then kill the hand within 15 minutes.
• After a 2-minute break, another 50 monsters spawn; clearing them brings out Maya's Right Hand, again with a 15-minute limit.
• After another 2-minute break, 50 more monsters must be cleared, and then both hands appear together and must be killed.
• Anyone who dies is moved to the safe zone of the second Kanturu map. If a hand is not killed in time, every participant is moved there. During each break new players may join to fill the group back up to 15.

Once Maya falls, the group is sent on to a second boss map where Nightmare waits, who must die within 20 minutes. He calls in monsters three times and teleports away after each summon, and his summons must be cleared before he can be killed.

Beating Nightmare opens the Refining Tower for 23 hours, and while it is open every player can enter, even without a pendant. It stays closed until Nightmare is defeated again. Inside, the NPC Elpis refines Gemstones into a Jewel of Harmony: talk to Elpis, choose Refine Gemstone, place the gemstone and confirm.

• The fan wiki gives a 50% success rate; a failed refine destroys the gemstone.
• The official Season 16-1 update changed gemstone refining to a combination window costing 50,000 Zen per gemstone, and it names the Kanturu Maya zone as a source of gemstones.
• Items strengthened with a Jewel of Harmony used to be locked to the account. The same Season 16-1 update made items with harmony options tradable.
