Sky Essence  

Ok I just want to post a bit more detail about this world event.
When you get a sky essence you go to Nek, or CL or any place with a spire (except EL1 & EL2 for all you blackburrow people, Amend and Relics of a Dying past already did it for those zones) the spire will most likely be a bit farther then it was originally, but it should be in the genreal area. You talk to a Gatecaller Lead Scholar and you will get a choice to go out and get some more Sky Essences from magic creatures (shadowmen in nek give alot) in any zone or craft materials needed for the spire building. The materials needed for the spire building are according to your tradeskill class
Craftsman- SUPPORT BEAMS, s/he will give you a book and you will be able to scribe it, talk to the gatecaller suplies person and s/he will give you your raw materials you need to buy the fuel (100 is only 14s!)
Outfitter- ENERGY CONDUIT, the same thing for crafstman
Scholar- BINDING RUNE, the same thing for the other 2
(youll know when the spire is completed when you view the status and it says 100 out of 100 is completed) After people complete the spires the gatecallers will start to freak out so dont freak out but a dragon will be flying your way, it wont be targetable for a bit while its flying toward the center of the spire. Once Exenka is in the center of the spire, Exenka will become targetable and turn into a level 60 epic x4 mob. Then after you kill him/her you will get a house item I think its a spires replica. The item s/he srops is called Eye of Exenka-

+10str +10agi +10sta +10wis +10int +65health +65power
+900 vs divine +60 vs piercing +60 vs slashing
slot: NECK
you can only use it at level 60 though!!!!
Ok it took me 2 hours to write this stupid thing now I hope this helps all you peeps out there!

used in the building of the wizard spires
