Ionian Boots of Lucidity
Lich Bane

Rabadon's Deathcap
Zhonya's Hourglass

I use this build while using Sona and I'd rate it an 8/10, I've had great success using this build.

Was trying this build with Kassadin it's pretty good



My score could have been better if i didn't had to minimize LoL every minute to take rsgp orders...

Builds aren't really too important because of possible changes needed. Also, different champs need different items to function well.

OT: Warmogs/Rylyz is used in everyone of my champs.

I play alot of AP/Tanky characters but it varies in games.

RoA
Merc Treads
FoN
Rab's/Abys Scepter
Frozen Heart

Last item varies between defensive/offensive items depending on game.

__________________

It varies every single game dependent upon what role / champ I'm playing.

But even more dependent on the enemy team.

Beserker greves
infinity edge
Phantom dancer
Rylais.
by then the game is usualy over. But it differs pretending on which champ im playing.
