•In lane, use Q to blunt the spell that actually starts the trade and sneak W autos wherever you can, because Kassadin’s early lane is really a shield-and-mana management problem, not a poke race
•Treat level 11 as the spike that runs normal games, and only pre-stack Riftwalk when the fight is real so the first R still leaves mana for W, the reset, and a second jump
•Most good Kassadin games start when mid or the first nearby jungle fight finally walks into your timer, while early roams from a bad wave are one of the recurring ways players throw away the champion’s takeover window
