This build gives you sustain, CC, tons of magic pen, tankyness, and a lot of chasing power.
Although a great build, it's quite bland.

ALL THE MANA AND REGEN
Might be the same items over and over again, but with singed passive, you'll be tanky as ****, and use practically no mana.
A great build, and one of my favorites :)

THIS IS MY ABSOLUTE FAVORITE SINGED BUILD.
Although not that tanky, you gain tons of ap and just enough sustain to last you in lane.
You can't initiate fights, but you can steal all the kills in them.
Your flip, will deal tons of damage, and it will make phreaks tons of damage look like a scratch.

You're one tanky bastard.

Well. Iceborn LB singed is amazing, and hard to play.
Have fun, summoner, welcome to the most challenging thing you will ever do.

Ohmwrecker and twin shadows are the core items that make this build what it is. Twin shadows and Ohmwrecker, not only will help you in diving, but will help you in ganking, and your archangel and ROA will make you just tanky enough to avoid being destroyed by anyone.

Your Spirit item, combined with all of your AP, will assist you in not running out of mana and farming faster.
basically all you need to know
