The Path of Time I - Suitable for Clerics 40+, Other magicians 45+, Other classes level 50+.
Monsters Platoon Chrono (Lv 41, 2100HP, 99xp, undead)
Notable Drops Esther Shield, 60% glove scroll for attack.
Pros Good drops
Good money

Cons Not exactly the fastest experience unless you're a cleric
or a Bandit Chrono's magic attack hurts a lot if you're not a mage

Comments Platoon Chronos have some of the best drops in their level range, and pretty good money. Unfortunately, this has also attracted a large number of people training on them. Still, a good alternative to just about any class once you're on the right level. Watch out for their magic, because it hurts.
