hi all this is my first build and i dont know if you will like it so ...
I haven't played much with tryndamere but think that with ability power he will be better.
Yy first game was perfect and with sinning slash i was dealing 1k damage and more,
if had more time for items.With ability power tryndamere has 1-1,5 k heal and with the
ultimate you can't die for 10 or more seconds.

i chose those items because you have more then 700 or more ability power and your heal is insane
you will deal a lot of damage with sinning slash.
i have played a lot with this and i think this build for ability power tryndamere is good.

I made the masteries like that becuase tryndamere is an attacking champion
and you need it for the critical strike chance and damage.

i chose flash besause you can escape after kill someone with the ult
and i chose ignite because it gives you ability power while its recharging

Go farming the rock monster that gives mana and cooldown recharge will
help you with your heal and ultimate to recharge faster.

If you want to play better with ability power tryndamere you can by only
ability power runes but you wont have and critical strike chance but with phantom danser
you will make it.
Or you can buy only attack runes and you will have less ability power but you will
have bigger chance with the heal and deal the same amount of damage.

With this build you can tank your team for 10 mabye 15 sec with your ultimate and heal
then you can go back for sometime to kill something to get stacks for your heal and go back
to battle with your team mates.

Upon starting each game, I'll pick-up and 5 This is more than suffice for jungling. At 1:40, start and complete in this order: 5->3->2->1->recall->5->4->3->2->possibly dragon if you can get aid or happen to be full health with enough elixir and pots left. From there, you can choose to continue jungling or gank/aid lanes.
