And Underdog’s Secret is an ability that can customize Double Overdrive onto a weapon - an auto-ability which doubles the amount of overdrive a character earns. ..

Where To Get Underdog’s Secrets

Final Fantasy X is one of the rarer games in the series. In fact, the only enemy that drops it is the Monster Arena creation, Th’uban.

The Underdog’s Secret is a monster that can be battled after unlocking six other monsters in the Species Conquest category. It’ll drop one Underdog’s Secret per fight.

The other ways to obtain Underdog’s Secrets are much more difficult.

During the siege of the Al Bhed Home, some of the invading Guado summoned a Chimera for you to fight. ..

This Chimera can be bribed with 180,000 gil for 15 Underdog’s Secrets. If you have the money, you can get the secrets.

The Al Bhed Home is a key part of the Siege on the Al Bhed. If you leave that area, all other Chimera in the game will give you Mana Tablets for the same bribe.

You can find all the Al Bhed primers scattered around Spira, but it’s a one-time thing.

Farming Th’uban is the only way to get as many Underdog’s Secrets as you can.
