This build is tested and certified for use in PBE. Please enjoy trolling your opponents with insane mobility and elusiveness!

This build utilizes Kassadin's incredible mobility to both hunt down enemies and escape from the most unfavorable situations. With the short cd of R, silence of Q, and aoe slow of E, Kassadin will stick onto targets and disengage quickly when necessary. Use of a QSS allows for removal of hard CC like roots/snares/stuns so you can R out of there and live to slaughter some more noobs.

This build allows you to chunk enemies while sustaining almost no damage. There isn't even a need for lifesteal because warmogs/GA/qss will provide plenty of tankiness. With a 46% critical damage bonus at level 18 with over 50% crit chance, each AA will hit like a truck. Each magic damage hit you take, your attack speed will increase due to the amazing passive! This allows you to reach max attack speed and shred casters if they try to fight back. If they run, there are endless ways to chase them down.
