Tryndamere is a somewhat hard champion to use. Either you understand how to use him, or you don't.
Flash: This spell... WILL SAVE YOU COUNTLESS TIMES
Pros: Uber Tower Diver
Cons: Super Squishy, Not a good pusher
Bloodlust: Kill minions. Get stacks. Get health. Tip: Critical hits will earn you stacks too.
Mocking Shout: Slows enemies that are facing away from you. Tip: Don't forget that this ability also reduces nearby enemies' physical damage.
Spinning Slash: Damages all enemies you spin through. Tip: This ability is also a wall hack. Use it to spin through thin walls. Escape with Style!
Undying Rage: Use to tower dive enemies that are low on health. Tip: Use as late as you can, for full efficiency.
