AP[]
AP
Action Points (AP) are stamina that resembles a green lightning bolt. It is a common energy system universerly used in gacha games that limits the amount of action that the player can make.
AP is mainly used on missions and events. When teachers achieve 3★ in a stage, the rush function is unlocked which allows them to skip the battle directly to the results screen. Teachers can hold a maximum of 999 AP with any leftover sent to their mailbox.
1 AP is refilled every 6 minutes and 1 experience point is given for every 1 AP spent. Sensei can increase their AP limit by leveling up. Should teacher reached level of 70 or above, they will need around 20 hours to fully refill their AP assuming they started from 0 AP. AP can be refilled 20 times with Pyroxene. The price will increase with every 3 refills up to a maximum of 300 Pyroxene. One of the Daily Achievements require Teachers to refill 1 time. Refilling is worth considering when Double Drop Event or Events in general are held.
