He can do it. He's magic.

See how he makes another typo in his typo response? Classic!

And just to show off the grammar nazi that I am...

"Which are the quickiest, and which reward the most money?"

Quickiest isn't a word. The correct term is "quickest" (a lone i in there, eh?). But don't feel too bad, LOADS of people do it:

Chuck Norris manages six, and he does them quickier than anyone else.

I think you might be able to do 5.

Do the 3, kill a liche, go do 3 more.
Doing it in half an hour... not so sure.

I hate the oracle ones. My wife is grinding them and they are HORRIBLE. The buff quest for them is about worthless. A priest with that buff is just as dead as a priest without it. Their trap one apparently had (or has) a bug where you need to tag them to get to loot them, and the vehicle one is only okay. The shinies quest takes a while and skill can't really speed it up.

The frenzyheart, meanwhile, have a quick quest to grab chickens (like really fast if you are good) and their buff makes a priest dangerous in melee (weird to see). They traps are pretty effective (cycle through them and everyone dies.) The vehicle one is pretty fast.

If you are looking for speed, go with the jerks in frenzyheart hill.

And none of you grammar/spelling nazis picked up on:

"It's not a game for kids or people who's interests change every day. "

Who's means "who is." "...whose interests" would be the proper usage in this situation.
