This is my first guide on mobafire :D pls dont judge me too hard if it wont work ! O_O
I choosed this items for some reasons ! I build him tanky with Hourglass and the Abyssal Scepter for more defence and some good ap items for the extra sexual BOMM effects :D

I choose this runes for the defensive last stand **** ! They are very importand if u want to go solotop ! The damage output is given by the items so you should not have problems with killing your opponent!

I choose exhaust and ignite for a better dmg output... u dont need something like flash becouse u go for offtank items/skill etc etc! You mostly use exhaust and ignite in combination with your ult to make it even more effective! In some situations exhaust can save your *** but in general u should not have soo much problems with that!

This mastesries are for more health/armor and magic resistance. Its importand to choose the defensive tree to make you more tanky and let the enemy lose their teeth at your massive body!
I also choosed cooldown reduction for lower cooldown on your ult and skills to charge your shield more often and for giving you a better dmg output.
