English Mirror
This plugin requires the Skill Core plugin and enables a Party Limit Gauge for both the player party and the enemy party. These gauges will fill up or decrease depending on what actions take place. The amounts they raise can be adjusted within the plugin’s parameters to your liking. Once a party has enough of the Party Limit Gauge, members from that party can use it as a skill resource to unleash powerful actions in battle!
