Record of Agarest War Zero

You cannot unlock this trophy until your second playthrough unless you loaded a Record of Agarest Clear Save File!

The titles will be the biggest grind in the game, you want to utilize every link in the Agarest wiki displayed at the top of roadmap. The most troublesome titles will be:

• 118: Weapon King (Collect every type of weapon)
• 119: Schneider (Collect every type of armor)
• 120: Ringmaster (Collect every type of accessory)
• 121: Perfectionist (Collect every type of item)
• 122: Proficient (Learn every available skill)

You want to start your title grinding after you reach the Boundary Edge, the Boundary Edge is much too hard so starting the title grinding at this point will allow you to obtain the materials to create better equipment in preparation for the final fights of the game.

Other Notable Titles:

113: Demon Slayer
It seems that sometimes Demon Lords aren't registering for some of the time so don't freak out if you end up killing more than half of the amount you are supposed to. Some solutions are to finish all other monster killing titles before finishing this one and it should start registering the Demon Lords you have killed.

118: Weapon King
You do not need Monster Weapons towards this title.

144: Time Lord
You need to kill the Mobius in the Boundary Plane for this title not the Mobius during Digest mode.
