Doomtrain is a very powerful Guardian Force due to the number of status effects it can inflict when cast on an enemy. It can also be created and added to your team much earlier in the game if you take some steps to prepare properly, so make sure you get Doomtrain as early as possible.
Attack Name: Runaway Train
Attack Effect: Normal damage plus random status effects
How to Obtain Doomtrain
