Thank you for the play and feedback, Allekid!
There are 3 ways to gain abilities:
- 1: As you said, earning TP after battles and spending it through the Skills menu (this sometimes unlocks higher tiers). Skills gained this way must be equipped to use.
- 2: Talents are abilities gained through traditional method of leveling up (e.g. Pokemon) and are related to a character's inherent class/personality. Talents do not need to be equipped to use.
- 3: Scanning: A battle command that allows a character to gain an attacking enemy's skills in exchange that the character skips their turn to observe and download. Scanned skills usually are equipped to use immediately if there's an empty skill slot. If the scanned ability is gained with no empty skill slots, a skill must be swapped out for the scanned ability to use after the battle.
