This build is specefied to kill ad carry champions like butter, in 3v3 maps this will definately kick ***, i was against a feeded xin zhao, a Tryndemere and a renekton, all i can say is that everytime they aproached me there wasnt very much left of them afterwards.

the reason i've chose these runes is becouse;
Quints: Health quints are always usefull when you are a tank
Marks: mana per level is because with my build you dont end up with much mana lategame so it's nice to have a little extra in the end
Seals: Armor seals = ideal against AD champs in my build
glyphs: always nice to have if you are against those nasty ap carries ;)

Why go directly after warmogs? yeah i know shoes are important but if you get some early kills and play a little defensive then it all should be alright, that's why i get my "w" ability faster, so i can slow my enemies AND CHOP THEN TO DEAAATH.

ninja tabi or mercury threads? it really depends on who you are against! choose carefully.

Thornmail: a powerfull weapon against those ad carries and fighters!

Frozen mallet: Very good for hunting fast enemies down.

another warmogs?: yes, again this is a question on who your enemies are, if you are agaisnt alot of ad, then get 2 warmogs, if against alot of ap then get a force of nature instead.

Guardian angel: why die faster when you can come right back into the fight again and get that pentakill you always wanted? that's the reason for guardian angel.. i've scored 2 pentakills now just becouse of that, such a lovely angel :)

as explained in the section about runes, clarity is very usefull becouse you dont end up with alot of mana + remember to keep stacking q spells!. flash is always handy when fleeing or approaching the battle on the other side of a wall.

and my masteries are basic tank masteries very usefull for longer survivabillity. amd capable to remain steady during cc effects
