Fury:Tryndamere gains 5 fury each time he lands a basic attack, and 10 fury on critical strikes and each time he kills an enemy. After not dealing or receiving damage for 8 seconds, Tryndamere loses 5 fury per second.
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.
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 30 / 50 / 70 health.
