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.
Mocking Shout cannot be activated unless an enemy is within range of Tryndamere. Due to this, it is possible to use the ability to scout in the Fog of War and provide pseudo stealth detection of enemy champions.
Mocking Shout will briefly provide sight of Tryndamere if he uses it in the Fog of War.
Cooldown: 13 / 12 / 11 / 10 / 9
Active: Tryndamere performs a spinning slash to the target location, dealing physical damage to enemies in his path. The cooldown is reduced by 1 seconds whenever Tryndamere critically strikes and doubled against champions (2 seconds).
Spinning Slash grants 2 Fury per enemy hit and 10 Fury per unit killed.
Active: Tryndamere instantly receives Fury and becomes immune to death for 5 seconds during which his health cannot fall below 1. This move is usable even when stunned, silenced or suppressed. This ability has a 0.5 second delay before activating.
If Tryndamere is below 3% health when Undying Rage ends, it will heal him to 3%.
Undying Rage has no cast time and does not interrupt Tryndamere's previous orders.
Drain-type effects such as life steal and spell vamp are applied before the damage reduction of Undying Rage takes place. As such, these attacks will heal as if the full damage was dealt, despite being unable to bring Tryndamere below 1 health.
