In area 4 on this map you’ll find the Tarantulas. In my opinion there isn’t an easier place for low level characters to grind. I’m talking about the high GC to low OC levels. From GC12 to about OC4-5 you can grind away on these guys and level fast. They are slow moving and rarely gang up on you, so you can focus on one at a time, and keep your Blood Count moving along too.

If you grind here during a double XP event you can easily pick up 5 to 6 levels in a short time, and as a bonus there are several quests here too, including Thief Ma’s pile of dirt that you’ll have to beat up.

If you do it right, you can get several things done all at once, just by grinding on the Tarantulas.
