FFT 1.3 is a fan-made modification of Squaresoft's game Final Fantasy Tactics for the Playstation and Playstation Portable gaming systems. It greatly increases the difficulty of the game and rebalances gameplay mechanics. 1.3 is not a storyline patch and does not affect the game's plot or character development.
This update to Final Fantasy Tactics 1.3 adds Marche from FINAL FANTASY TACTICS ADVANCE to 1.3 and fixes some minor display bugs. It also rebalances some parts of the very difficult Deep Dungeon and throws some minor buffs to some items and gives Mustadio a new skill - Mosfungus Bomb.
