This guide is straight damage. You will be able to survive with your ulti so not much survivablity is needed. This build is highly dependent on your 20% crit chance from runes. Im not saying your gonna go 20-0 every game but by late game no one should be able to take you 1v1 or 2v1 depending on the champs.

The reason for going with full crit chance runes is because Trynd is highly dependent on criting for extra rage and damage. If you get lucky and crit 2 times when you first step in lane you should be able to obtain first blood unless they flash away or something.

Full offense with the improved ghost so you can run people down and to build into more experience. The faster you hit 6 the faster you can basically run around and kill people without fear.

Items as I said you want to have the 20% crit chance from runes and then the extra 2% from masteries. So with rage you should have enough crit to start with. So lets get into it starting item whats better damage hp and lifesteal or just a crit glove of course I would go with the blade a lil life steal to stay in lane longer and more hp. So now i build right into boots first to get the attack speed and movement speed. This allows you to chase and build rage more effectively. Now i suggest building the Crit cape and Pickaxe first and then grabbing the Vampiric Scepter. Because this will get you crit damage and more life steal all around better then rushing the BF sword because "I WANT MORE DAMAGE!". So now finish your Infinity Edge so now you can do some really good damage but the tanks and smart carries are building armor so lets go to your next great item the Black Cleaver this gives damage and attack speed and also reduces armor so you can spin out and by 3rd hit the squishy is dead :'(. Now I build Phantom Dancer because who doesnt like to crit more attack faster and run faster whos gonna get away from your spin, slow, and chase combo now? maybe Singed and Temmo just because their run speed buffs. Now to finish it off Build a Bloodthurster with this you should be able to kill and out heal a thornmail on a tank. For now you can sell your doran's for whatever you feel like you need more defense or just go for more damage its up to you just pick something that will help you kill without dieing.

Why ghost and exhaust? Because Trynd is highly dependent on mobility to get close and to run away and if you have another melee and you exhaust is a great spell to counter and use for offense.
