The 'event time' for the Demonic Swords are completely bonkers for Naia. Basically if you can hold the sword till after 11pm you'll keep it for the reward. Majority of players will log off between 11pm and 0am and there is nobody left to compete/fight the chest. And if you are, you'll run into protectors.
And then you have the douchebag move that people do and just camp Blackbird Campsite, Parnasus, AF Instance NPC etc. for easy leveling up of the sword.
