WOW PowerLeveling: You can probably level here because it is empty in the game
Monsters - small thief bugs (mobber), female thief bugs (mobber), familiar (agro), poporing, tarou, hydra (agro, ranged) Tons and tons of WOW PowerLeveling things to kill on levels 2 and 3, you can probably level here because it is empty; the place is just yours and yours alone.
Loot - A+ you and l find a ton of stuff, this should finance your chain easily if you need one still.
Payon Caves aka rcher dungeon (vit only, with divine protection/angelus)
Mt. Mjlonir (e, n, e o Geffen) Horn map
Levels 30-40: Weapons to bring-Fire/Wind
Monsters - Horns, chocos, ambernites, poporings. This is where I leveled, and leveled and leveled, I did not really know much about making a priest, I was here until job 40, which seemed an eternity, do not stay here that long if at all possible, make a merchant and do some buying and selling, get some good gear, just try not to be here for ages like me.
There is nobody here now, it used to be bot ridden, but it is not bad now.
Flee needed-100 is nice, but 80+will suffice.
Loot - A, horns drop (or used to) a mid ranged spear every so often, these go for about 7k each, which is nice loot.
