Hidden potentials - Some units at level 20 may still have an empty slot for potential. You can unlock that hidden potential by getting 5 points by completing the following tasks. Then, go to Castlefront Street, and talk to Ellet. She will say she interviewed a rising star from your squad and unlock the hidden potential.

Participate in a battle (1 point).
Kill an enemy unit, heal an ally, repair cover (for example, a sandbag) or tank (2 points).
Capture a base (3 points).
Save a fallen comrade (4 points).

Note: To get five points easily, enter Skirmish 1. Have a unit kill another allied unit. Collect their body to get 4 points for saving them. Select another unit, then kill the unit that was killed previously, and repeat.

Easy experience points - Enter a skirmish. Use "Caution", "Evasion Boost", and "Defense Boost" on Alicia. You will lose health very slowly when taking fire. It will take two turns to reach the end. End your turn while Alicia is safe somewhere along the way to reset her AP. Note: If you have Largo and Rosie in your squad, you will get a free CP.
