Thaumachine and Bombs

The Thaumachine battle in Radiant Historia is considered to be the toughest boss due to the bombs that the Thaumachine spawns that will deal a massive amount of damage to the party when they self-destruct. The general tactic to defeat the Thaumachine is to have a party of:

• Stocke,
• Aht,
• Rosch

Since Aht and Rosh both have skills that deal area of effect damage to entire rows.

The general tactic is to first eleminate the bombs in the back of the field and to have either Stocke or Rosh push the Thaumachine to the back row of the field. From then on, the Thaumachine will only spawn bombs in the middle row of the field. Now that the bombs spawn in the middle row, the Claw skill of Rosh can be used to eliminate the bombs in the middle row all at once. Finally, Aht can be used to place traps and then Stocke can use the left or right assault to push the Thaumachine into the trap thereby dealing massive amounts of damage.

The tactic repeats over and over again: Rosh eliminates the middle row of bombs and Aht and Stocke push the Thaumachine into traps till the boss is defeated. The tactic relies on the fact that the Thaumachine will only spawn a single row of self-destruct bombs in case the Thaumachine is pushed to the back of the field instead of spawning four separate bombs in all corners of the field.
