Ungarmax is the Level 1 Limit Break for the Warrior of Light and their Adventurer Squadron while undertaking Command Missions. Using it causes the Squadron to deliver an attack similar to Final Heaven while also providing a 15 second damage boost.
Ungarmax also refers to an exploit that allows the usage of Ungarmax Limit Break outside of Command Missions using /ac macro. This exploit remained hidden from the development team of Final Fantasy XIV for an extended period of time. When the information about this exploit started to spread among the playerbase, the development teams took notice and had taken down all servers for emergency maintenance to fix this glitch, to punish players who abused this exploit, and to improve their anti-cheat measures.
