From EZ Server Wiki
During your time on EZ Server, you will need to kill lots and lots of willowisps. They drop Greater Lightstones which combine to Superior Lightstones and are a requirement for many of the gear needed to progress on the server.
- The primary hunting zone used for willowisps is Jaggedpine Forest
- Having the Free Waypoint makes this process easier as you can repop the zone after killing them all or create guild, raid and solo instances.
- New players to the server often farm these and sell them to higher tiered players as a way to earn plat.
