Not Updated For Current Season
Alright stop laughing for a second and hear me out.
HP Tryndamere: Who is better for a DPS tank? You can become invincible for 5 seconds, heal yourself for massive amounts with a free ability and lifesteal, slow enemies and you have an easy, damaging escape move. With this build and similar builds I've gotten over 7000 HP, and alot of attack damage. It can work, I swear!
Just get basic attacking runes (crit chance, attack speed, crit damage etc). Not too important here. Crit rate runes are especially useful.
Now here is where it gets interesting! The first time I tried this build i was bored out of my mind and wanted something new. My teammates almost cried when I told them I was going tank, and the enemies laughed half the game, until i started destroying them. First up you want boots, beserker greaves or ninja tabi. Then you need some lifesteal and maybe crit chance. Executioners calling or starks fervour are excellent choices. Now to get health: Warmogs or frozen mallet. And now, the trump card! ATMAS IMPALER! Lots of attack damage, basically free! This item is essential to the build. From here on you'll want to stack health and/or armour and magic res. Health is the most important however.
Bloodlust, bloodlust, bloodlust. Get one in mocking shout and spinning slash early, and get endless rage when you can. Simple.
Ignite is always good, as is exhaust. Heal is useful as another income of health, and ghost can be useful for getting out after using your ult.
Keep this up when in combat unless you desperately need the HP, as it raises your damage incredibly.
Use for escaping or chasing down, should be obvious when it's needed.
Use for damage output, escaping or chasing, very versatile.
When enemies overcommit, use it. When you don't feel like dying, use it. When one of teemo's stupid mushrooms hits you or if Kathus's OP ult is activated and your about to die, use it. If your turret diving use it. In fact just use it if you're going to die.
