Lunarion is a hidden boss placed in El Morad or Lufferson, and just like the lizardman, its not placed in most databases and its not easy to reach.
For those who doesnt know what it drops:
Gornak's axe, Karghot's will, Grond's Hammer, Howling Rooster, Dragon Slayer Scythe, 2500Hp scroll, 350ac scroll.
Remember the 7 guardian keepers of the key? Yes you need to find them again, but you need to be at least lvl70 to do it, and all village quests (bellua, linate, roan camp, lufferson) must be clear before you start it. You also need to be a Knight.
First Step: Make a complete set of destruction, and wear it.
#2: Talk to the keepers, in the right order.
#3: You'll be teleported to another of those "quest maps", go through the monsters, make it to the end and kill the monument.
#3: After that the boss will unlock and spawn, being hittable only by the party members of the quester. It spawns near the Viking boat, near Harpys.
#4: good luck.
Remember guys, just like any other boss, it wont spawn in less than 12 hours after it got killed first time. So if you do the quest again soo you'll notice the monument is not there.
