Monster Sanctuary how to easily beat Marduk and Mad Lord Guide with Monster Builds
Apparently a lot of people are struggling on this final fight so I constructed a team to beat it easily. Caraglow, Magmapillar and Catzerker carried me through the whole game until the final tower when I added arachlich and Dark Sutsune. Doesn't matter what 6th monster is as this team can easily beat any fight in the game. This team is also very easy to use, you can always just use the same ability for each monster.
Magma-fireshield
Sutsune and Caraglow-mass restore
Catzerker-long slash
Arachlich-encapsulate
