Huh.
Just figured out that AP Yi survavibility in Fight and Teamfight is way higher then AD Yi, somehow is lifesteal allow him to get back HP on enemy pretty fast, just like Aatrox lol.
Still trying to find some build Path including the core Item
Find three way to build AP Yi
Tanky :
Sated , Guinsoo , Hextech , Boots (Mercury) , Tank Item, Tank Item
AP Tanky :
Sated , Guinsoo , Hextech , Boots (Berzerks) , Rylai , RoA ? Something like this ?
Full Squyshi Aatrox Like :
Sated, Guinsoo, Hextech, Boots (berzerks), Nashor tooth, Blade of the ruined king.
Rylai work pretty well on AP Yi, the slow effect apply on Q allowing him to chase down enemy easier, and since guinsoo convert AP into damage on hit, this allow to deal more damage, to get less squyshi and to slow enemy.
But since the slow effect apply on Q, you can basically slow 4 enemy , right ?
Feel like this could be broken
