What are the required quests to go on a Zakum run?

I know theres one for the eye of fire but are there any others?
And also do you think i can finish them in 1-2 days?

You have to complete the Zakum Quests, which are divided into three levels.
The first one is a somewhat Party Quest, although you do not have to be with a party (just in a party).
The second level is a Jump Quest, I've been told it's the most difficult in the game. Although I find it somewhat easy, compared the the Sabitrama jump quests.
The third one is just collecting 30 Gold Zombie Teeth.

Yes, they can be easily be completed within 24 hours.

Thanks,
Are there any pre-zakum quests that you have to complete? (before going in the altar)
Does the altar NPC tell you what quests you need to complete?
Are the two pre-quests, the eye of fire and the zombie teeth quests?

Edit: Also on Mapletip is says that there is a big quest line that involves going to
Grendal, Korean Folk town, and EL Nath. It seems pretty long to me.

You don't need to do that. Just do the 3 Abodis (sp?) quests.

Oh, and ask your 3rd job instructor for permission before going, of course.
