What is the quickest way to gain exp in GC Offline?

I just do the Forest part of Soul Of A Blacksmith over and over. Is there a quicker way?

I don't do quests. I use to do forest runs with my fomar. Now i'm just doing regular ruins runs. Tons of enemies with lots of exp. Not very hard either. Seems good for me. Plus im hunting df field, sorc arm, morning glory etc there.

GC offline, I just do whole game runs. But that's just me, and I haven't played offline for a while now.

I find Addicting Food is best, mainly Cave 1 and 2. sure there's no boss but there are loads of enemies which give more EXP than in the Forest. plus the Caves usually have better drops

Since GC offline doesn't have a quest with loads of enemies in a short amount of time (except maybe Soul of Steel's first room, but...The cutscenes before that waste considerable time), I'd say do your EXP grinding according to what you're hunting. In my case, I'm doing Doc's secret plan, since I'm hunting a Sorcerer's right arm.

I would maybe choose soul of a black smith or doc's secret plan

Also u can grind in the mines. Or the quest Unsealed Door gives pretty good exp. since at the end u fight De Rol Le. depending on your lvl i would say choose this one if you are able to handle that boss.

Forest, mines, forest, mines, forest, mines.
Do the occasional ruins, avoid caves.

I usually do forest mines then addicting food then ruins

i say do forest last, like when u need just a quick run through of something to get that fast exp for the lvl. but yea you have a good layout of stages to go to.
