To farm EXP in Metaphor: ReFantazio, you can follow these detailed steps:

### 1. Identify Farming Locations
Metaphor: ReFantazio offers various locations where you can farm EXP efficiently. Here are some of the best spots:
– **Nord Mines**: Specifically, Dig site 2 is recommended after defeating Captain Klinger. This area contains Serpetia, Gelatinos, and Feral enemies that can be defeated to gain EXP and MAG.
– **Tradia Desert**: The Traveller’s Graveyard in the Tradia Desert is another prime location. It contains Sandworm Valmo and packs of Hyeno and Wild Corvo, which provide significant EXP, A-EXP, MAG, and Money.
– **Orbwise Path**: This location is particularly useful during mid-game. It includes Aquatic Shuper level 20, Terrestrial Shuper level 33, Waterworm Valmo level 35, and Kapcerto Sondro level 36. Clear the dungeon first, then farm the sea slug-like monsters and instanced battles with Waterworms and Kapcertos until you reach level 38 or run out of mana.
– **Tower of Insolence**: This area is best accessed after making liberal use of the Orbwise Path spot. It contains Psyocro level 45, Psyocropos level 50, Guptauros level 35, and a single Guptauron level 55. The six Psyocropos offer significant gains in EXP, A-EXP, MAG, and Money.
– **Tyrant’s Star**: This is considered the best farming spot in the game. Clear Melancholia’s Threshold until you reach level 77, then begin full-clearing Melancholia Depths on repeat. This area also has a random chance to encounter giant teeth-like Argent-Crown Homo Tenta and Or-Crown Homo Tenta, which yield massive rewards.

### 2. Farming Strategy
To maximize your farming efficiency:
– **Clear and Re-enter**: Clear out a loadable area of enemies, then leave and re-enter the same area to have them respawn. This method can be repeated infinitely if the enemies are weak enough to be killed in overworld combat.
– **Elementas**: These enemies give out significant MAG, A-EXP, and Money but do not respawn when an instance is reset. They must be locked down when spotted to avoid escape, and they need to be beaten within one turn to avoid fleeing.
– **Instanced Battles**: Focus on instanced battles with monsters like Waterworms and Kapcertos, which provide high EXP gains. Clear the minimum amount of Shupers while rushing to these monsters for optimal results.

### 3. Additional Tips
– **Unscathed Triumph Bonus**: Manage to get out of Squad Battles without taking damage to receive the Unscathed Triumph Bonus, which increases your rewards. This is a guaranteed way to farm for any resource in the game.
– **Trance Crystal**: The Trance Crystal located in Regalith Cathedral will spawn enemies that you can farm for EXP, MAG, and other resources. Monitor its health and wait it out at a nearby Rest Area if it drops too low.

By following these steps and utilizing the best farming locations and strategies, you can efficiently farm EXP in Metaphor: ReFantazio.
