While the main story provides a good amount of EXP, sometimes you'll need to grind to overcome a particularly tough mission or boss. Here are some efficient methods:
- Secret Training: As mentioned in the 'Akademeia Activities' section, sending cadets on Secret Training is an excellent passive way to level up your entire roster, especially characters you don't frequently use.
- Replaying Missions: Earlier missions, particularly those with high enemy density, can be replayed for EXP and AP. Look for missions with 'S' rank potential for maximum rewards.
- Expert Trials: While challenging, Expert Trials offer some of the highest EXP and AP rewards in the game. Tackle them when you feel confident.
- World Map Encounters: Random encounters on the World Map can be a quick source of EXP, especially if you have an item or accessory that boosts EXP gain. Look for areas with stronger enemies for better returns.
- EXP/AP Boosting Items/Accessories: Keep an eye out for accessories or temporary buffs (from lectures) that increase EXP or AP gain. Equip these before grinding sessions.
- Phantoma Farming: If you need Phantoma for magic upgrades, replay missions with enemies that drop the specific type you need. The Arena can also be a good place to farm Phantoma from specific enemy types.
Remember to rotate your active party members during grinding sessions to ensure everyone stays at a comparable level. A well-leveled roster provides more tactical flexibility.
