Not Updated For Current Season
I prefer crit chance over crit damage because damage will come later but early high crit is killer for first blood, jungling, or soloing. I usually get the brawlers glove and complete the avarice blade before getting my boots. I figure since I will be making money faster then the other laners I would be usually be up an item. Initially I use to get my b.f. sword first but after playing for a while, I've noticed that getting zeal first is much more helpful. After purchasing boots, go straight to zeal. After zeal, work on your infinity edge. Get the b.f. sword as quickly as possible. When you can, finish infinity edge getting the crit strike cape before the pick axe. If your not doing so well, finish your phantom dancer. This should help with getting kills since your movement speed is more than likely faster than any other champion at this moment and your crits should be more common. Either way, you should be able to get both items. If you feel your low on money, farm creeps either in the jungle or in the lane. Farming creeps should be easy with your powerful auto attack and decent attack speed. After completing both the phatom daggers and the infinity edge, move on to the blood thirster. If you have enough money when you start get the b.f. sword, if not then get the life steal sceptor. Try to finish this item as fast as you can cause it helps a lot when fighting in team battles when your targeted first. The game should be almost over by the time you get the blood thirster and if not, get another phantom dagger to gain even more kills. Getting you last item almost never happens. But if it does the choice is totally up to you. If you want to attack faster, get a phantom dagger. If you want to hit harder, get a blood thirster. If there are a lot of tanks, get the last whisper. I don't recommend the ghost blade because I dont like stats but if you want to have it go ahead. Following this guide should lead you to lots of kills. The amounts of deaths are totally up to how good your game play with with tryn. You got to know when to get out when your ult is almost up and you got to know when to time your ult. You also have to be aware of the map because you dont want to get ganked when farming creeps.
For jungling you should start out with the green elixer and five health pots. If you prefer the cloth armor you can choose that instead of the elixer but i prefer the elixer. If you want to choose smite instead of exhaust or flash be my guess but i prefer not to choose it because it gives you up before the game making it possible for the opposing team to gank you when your jungling. If you dont choose smite then you start at the two golems then the four wraiths then the three wolves and use health pots when necessary. By this time you should be about lvl 3 or 4 and ready to take on the blue golem. After getting the buff the two golems should have respawned go kill them and work your way back to the wolves skipping the red buff. At this point you might be out of pots and low hp so go back to base if you still have decent hp and you see the other laners also low on hp you can go gank or continue jungling on the other side. If you decide to go back buy the avarice blade cause you should have enough money by this time and if possible buy your boots. go back and kill the red buff and wipe your jungle again. Should be about lvl 6 by now and if your have almost full hp go kill dragon and you can ask some of your team mates to help or you can go gank a lane cause you should be able to by now. By this time your more ganking then jungling grabbing buffs when you can. Just always keep an eye out for your lanes to help them follow the build as if you were laning and you should be fine. You might want to finish your phantom daggers when you jungle because that helps with lane ganking. Squishy enemy champions are you best friends, remember that :D now GL and HF go get some aces and kills.
