Tryndamere's abilities don't have any cost related to them, therefore the use of his abilities is only limited by cooldowns. Instead he uses fury as his secondary bar. Tryndamere starts with 0 fury, and has a cap of 100 fury. He gains 5 fury per autoattack, plus 5 extra fury per critical strike and 10 extra fury per any unit he kills. When out of combat for 5 seconds, Tryndamere loses 5 fury every second.
Active: Tryndamere instantly receives fury and becomes immune to death for 5 seconds during which his health cannot go below 1 health. This move is usable even when stunned, silenced or suppressed. This ability has 0.5 seconds delay before activating.
