AP masteries are useless on this Tryn because you get an extra 10 AP maxed out, whereas with exhaust you actually get something, namely extra ArPen. You should be taking more points in Spinning Slash early, that will be your only damage source early and mid with the item order you have. B. Greaves, again, useless. Your ult does not save you from stuns or taunts, Merc Treads can and will. Reccomend you also take Cleanse instead of Ignite. Ignite is only useful early game for FB, after that it is useless since you can just buy Executioners Calling for the same heal reduction. Reccomend getting Ghostblade early for more crit + AS + CDR. Black Cleaver is better late game as mid and early tanks will have little to no armor right now.

well i took the points in archmage savy because i dont need exhaust at all since with the ulti you cant die and i didnt know what talents to pick. but i picked archmage savy with something in mind my abilitie (i thought it was) bloodlust improves so i will heal more and otherwise spinning slash can finally deal at least a little damage. i got the kill on invisable akali with spinning slash :P
then again your idea is good too it just depends on how you play tryndamere and what spells you use but still thx for the tip.

This is slightly different than how I used to play Tryn when I mained him, but I like it a lot. Hopefully the match doesn't last long enough to get all the items because this build completely wrecks the other team.

Your rune choices are especially good I think. I like the mix of crit dmg, crit chance, and armor pen. This build rocks.

+1

rethink ur talents and Ghost. Tryndamere doesnt need ap at ALL. He would benefit FAR more from taking the talent for imprioved exhaust. doing away witht he points in Archmage's savvy and the one for improved ignite could open up 2 talent point for anywhere and then two woud be contricted to the lower tier talents to keep the higher tiers open. other than taht looks good =D
