Overall, this quest is simple. Even without a guide. I was really shocked at how quick I finished this quest. For anyone who doesn't want to just go through the quest tab, here is a step by step (really just like 2 steps) to finishing this quest. I'll do some on other quests later on.
To start this quest off, you must go to the Mage Bank (Teleport Wizard -> PVP -> Mage Bank). When you arrive there, find and talk to Kolodion.
After a little bit of dialogue about things relating to the Mage Arena, he will say you must fight him. Agree to fight him (you must use only Magic in the arena!!). After killing him, he will morph into another NPC. He does this a few times, just keep on killing him. Then bam!! You are done.
The rewards are as follows:
* Access to Godspells (in modern spellbook)
* Access to god capes
* (1) Quest Point
* 30 Achievement Points
TIPS:
How to receive godcape:
Go into the whirlpool in Magebank, run North and pray at one of the 3 statues.
How to receive a God Staff (for god spells):
Go into the whirlpool in Magebank, trade the Chamber Guardian (each staff is 84,000 GP)
