Action

An action is a type of thing a unit does during its party's turn, during the action phase of the turn. For the most part, performing an action is using a technique. However, it can also mean using a consumable item, or using certain abilities' activated effects. A unit that "cannot act" as a result of a status effect or anything else cannot perform any actions.

Under normal circumstances, each unit may only perform one action per turn. Actions occur during a party's turn after dodging and row movement is decided, but before regeneration kicks in.

Additional actions
By default, only one unit in a party performs an action per turn, but a party can have multiple units perform an action in a turn, at a cost in EP. The first action performed by a unit in a party in a turn is free, but all additional actions require that 5 EP be paid for each action performed aside from the first. This cost can be split freely between any units in the party.

Normally, one action counts as one for the above purpose, but a couple of status effects modify this functionality:
 * Haste allows a unit to perform two actions in a turn, with this counting only as one action for the above purpose, or perform one, with this counting as 0 actions for the above purpose.
 * Slow causes a unit's action to increase its party's action count by 1, effectively making its action count as 2 actions under normal circumstances.

A party is limited to a certain number of additional actions depending on its level.

Examples

 * Three units in a party each perform one action. Since two additional actions are performed, 10 EP must be paid by the units in that party. This cost can be split as desired between the units in that party.
 * A Hasted unit and a non-Hasted unit in a party perform an action. Since the Hasted unit's action counts for 0 actions, the party is only performing 1 action, and does not need to pay an additional action cost.
 * A Slowed unit in a party performs an action. Since its action effectively counts for 2 actions in this case, 5 EP must be paid by the units in that party. This can be split between the units as desired.
