This may look like a troll build but its not. Pay attention to the runes I have set for this guide. Full critical DMG runes NOT chance but DAMAGE. This is not a cheap guide and mostly used for a late game Trynda build, therefore I focus on a defensive start to not fall behind. Full crit DMG runes combined with the 10% crit DMG from mastery's and Infinity Edge all give me a Critical DMG of 305,51%!
200 Normal + 50% from Infinity Edge + 45,51% from Runes + 10% from Mastery's
Item's & Play style.
Cloth armor and health pots are almost a must early game because of the lack of defense runes. After lvl 6 you could easily tower dive a low armor/health opponent with your ultimate, just make sure your rage is full for the 30% bonus crit chance. I have tried several games with this build buying Brawlers Gloves and it does not go well because of the fact that you are very squishy. Cloth and 5 pots has proven best so far.

I choose to max my heal first because its going to keep you alive if the cloth and health aren't enough. Also because of its passive which can really turn a fight around. Secondly I will either max my Spin or my Slow/DMG reduction. Slow/DMG reduction if my opponent is annoying and is looking for a fight constantly. My spin if I'm dominating the lane and want to burst him down quickly with spin > auto attack.
