Map 4-3: Nekos on massive Enemy Level-up Geo Field. Good for leveling and capturing high level Nekos.
Map 9-2: Pass 8 Stronger Enemy Bills(SEBs) so the Rune Knights are level 99. This level will give good experience up until the early 300s. All enemies are on a +50% Exp Geo Field.
Dark World 1-2: Pass one SEB and there are 4 Orcs at level 99. Orcs give better EXP at 99 then Rune Knights. Be careful the Orcs are on an Enemy Boost Geo Field.
Cave of Ordeals 1: Set off the geo chain to weaken the Archers. Throw the 2 +50% Exp Geo Symbols onto the Geo Field. Pass SEBs as needed. This level is good for training new characters for grinding on 9-2 or DW 1-2.
Cave of Ordeals 4: 8 level 250 enemies on a +100% EXP/Mana Geo Field. Pass SEBs as needed.
Land of Carnage Cave of Ordeal: Much stronger enemies and pretty good bonuses.
Item World: Can level-up equipment, collect felonies (+1% EXP per felony), collect treasure maps required to open Land of Carnage, can farm specialist, can get a hold many Rare and Legendary items, unlock special features, and find unique shops that sell interesting merchandise.
