Tryndamere's abilities have no cost related to them, and the use of his abilities is only limited by cooldowns. Instead he uses Fury as his secondary resource. 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. Using Spinning Slash on enemies also grants Fury. When out of combat for 8 seconds, Tryndamere loses 5 Fury every second.
Tryndamere receives 0.35% bonus critical strike chance per point of Fury he currently has, for a maximum of 35% critical chance at 100 Fury.
