The battle party's Affinity determines the number of Espers you can have summoned at once. The battle party's Affinity is the total of each group leader's Affinity. If the Affinity bar is full, you cannot summon more Espers.
In-game description
Affinity is a gameplay element in Final Fantasy XII: Revenant Wings. It is a numerical value that determines the type and number of allied Yarhi that can be on the battlefield at one time. The blue area of Affinity bar at the top of the screen shows the amount of Affinity currently in control of the party, while the full length of the bar represents the potential Affinity that the player party can gain.
Using Affinity[]
Each Yarhi has a different numerical value that stands for the amount of Affinity it uses while on the battlefield. New Yarhi cannot be summoned when there is not enough Affinity in control of the party. To gain more affinity, capture Summoning Gates. Each allied Gate adds 10 total points to the player's Affinity.
The Affinity used to summon a Yarhi will become available for re-use when that Yarhi falls in battle. This takes time, however, and the red bar that appears next to the blue stands for the potential Affinity that will be recuperated after a period of time. The player may dismiss a Yarhi to recuperate its Affinity for use in summoning another.
