GF's Attack - Runaway Train
Doomtrain's attack is elemental Poison based, which makes it useful against human enemies like soldiers. It also causes several abnormal status effects including Poison, Darkness, Silence, Berserk, Sleep, Doom, Curse, Petrify, Confuse, and VIT 0. Even summoning Doomtrain against enemies immune to poison can be useful due to the status effects.
Useful Abilities - Doomtrain has four useful abilities, Elem-Atk-J, ST-Atk-J, Elem-Def-Jx4, and ST-Def-Jx4. They're all hard to come by, but here they are all on one GF. Forbid Med-RF is also great, and Junk Shop is very practical, especially on Disc Four.
