Glooth Fairy

Access granted through the Rathleton Quest, where it can only be faced if it was the most voted one for the period. Talk to Flora here to spend 1 voting right to enter its lever room. When the lever is pulled, a message will appear (Everyone in this place will be teleported into Glooth Fairy's hideout in one minute. No way back!!!) and anyone inside the room will be teleported to the boss room after 1 minute. Be aware that when entering its lever room, you can not leave, teleport, or logout, and the only way to leave it is to pull the lever. The lever will only reset to its regular position after 16 minutes and 40 seconds have passed, so it is also important to not enter the lever room if it is not ready, or you will be stuck until the cooldown has passed. The fight itself is limited to 15 minutes.

Looks identical to a Glooth Golem.

Fights in close range, often will stop chasing a fleeing character and walk around aimlessly for 2-3 seconds before retargetting passing through fire fields to attack a nearby player.

Entrap him with Fire Field Runes, then strike, avoiding his beams. When he is deep in the red health, he will heal for about 12.5% of his total health (around 7,500 HP). So, focus your strongest attacks on him before he heals. However, he can only do this three times, so you can also just proceed with your attacks until he has been killed.

Another strategy is to use a Fire Wall Rune in the middle of the room and two Energy Wall Runes in the shape of a box while luring him over the energy fields while avoiding his melee attacks.
