So - Let's be creative and use this sandbox to our advantage.

As long as you don’t break Nova Barriers, enemies take only 1 damage, no matter how strong you are. This means long battles with no more running between spawns - just set everyone to Auto and relax. Perfect for grinding certain titles, that might be missing after Zhone Cage.

Some titles this helps:
- 10.000 Weak point / attribute hits still count even if the barrier is active.
- Arte Usage
- Crits
- Time Spent in Combat

The set up:
- Future Arc if you want to level Richard.
- Figurines for every character - Cheria and Sophie have almost no offensive Artes without Nova, so swap them out for Pascal or another character. Pascal’s "Infernal Prison" hits multiple times and is strong against the winged monsters for example.
- Arte Usage counts for the person you roleplay as - While the attribute hits and the crits go toward your own titles. Example: Richard roleplaying as Pascal attacks a flying enemy, farming Infernal Prison for Pascal while earning his own attribute title.
- Play on Easy - Mobs attack less, reducing spell interruptions.
- Put everyone on passive strategy until the mob has activated the barrier, then put your attackers on aggressive.
- Disable every Arte with Nova attribute.
- Disable Accel Mode for offensive effects - Hubert’s definitely killed my enemy, and others likely do too.
- Bring a healer - you don’t want to die to Curse after xxx minutes of AFKing.
- Equip "Book of Striking" for Arte Usage grinding and the "Book of Resrtcition" for Crits.
- Can find those mobs pretty much everywhere in the overworld later in the story.
- Depending on the amount of attackers the fight might end itself after a while. I found that if you have only 1 attacker and 3 healers the mob seems to regen itself after a while, essentially lasting you however long you wish - But with 3 attackers they slowly chip down the mob until it dies; after half an hour roughly.

Also credit where credit is due. I originally read a similar strat when playing the PS3 Version and finding a post from a genius called "mosspit" on gamespot.
