Defeat 400 monsters of the Gnole family that yield exp
Abyssea - La Theine, Luison Put on VV, RR and Apoc and you'll mow through these faster than anywhere else(see Talk page). Only downside to this camp is the amount of pet food you'll go through because these things hit decently harder than anywhere else. If you're like me: more worried about a speedy trial than gil.. this camp is the best.
Jugner Forest (S) The most ideal position to enter is via the Maw H-11 this takes you to the perfect place for the Gnole ,kill all the mobs you see and keep the river on your right, cross the bridge near the 1st raised platform you see and work your way back south again to the last bridge, cross again and you are back at the maw, rinse and repeat I took my NPC after unlocking the new raised level cap for them and she helped me a great deal and gained 4 levels during this trial GL!
for those of you without access to the Cavernous Maw warp via your home city [S] to Jugner Forest (S) due to the barriers in Jugner Forest (S) you cannot walk straight to the camp, head NW around the terrain past the Recall-Jugner G/H-9 then south to the Cavernous Maw camp/area
