FINAL FANTASY V FOUR JOB FIESTA

Geomancer in the 4JF has bad synergies. !Gaia is decent at best for white mages pre-Holy to give them some sort of offense, Equip Bells is only handy to Berserkers with the Rune Axe for the marginal magic boost (and even it is outclassed by !White/!Black), and the passive is innate to the class and you only need one of it anyways for the three dungeons it is relevant. Its even worse if you don't have a magic class to give it !Magic and take advantage of the Geomancer's decent innate stats.

The best I've heard with Geomancers is to give them the Air Knife and hope !Gaia rolls Air Slash (I think its the only !Gaia when fighting NeoExDeath at least).

The FF5 uber build is pretty simple: Equip !RapidFire (attack four times at half power, always hits, special weapon effects never proc. ps the best weapon in the game has a random "attempt to flee" proc that !RapidFire bypasses), two swords (double the attacks), and cast FlareSword for x2 power. Pass controller to dog and win game.

Meanwhile if you want to beat the game at levels 4.5 or beating the game with a single character in a single class you can do that too! FF5 is a game of options and they all work... to a degree.

(I think the only solo class challenge that failed was Berserker, the class that you can't control, against Neo Exdeath because of the limited RNG didn't have a situation where the berserker would get the right rolls needed to win. No other class had such issues because they could do things like "heal" and "choose to attack a real target").
