Do you have some tips besides the Kassadin Probuilds?
Besides checking out the available Kassadin Probuilds here are a few Kassadin tips, if you are an ally or enemy:
- Kassadin has multiple item paths; he can go caster via Mana and Ability Power or anti-caster with Cooldown Reduction and Magic Resist.
- Kassadin's ultimate has many uses and is on a shorter cooldown than most, use it often.
- Try to get the Ancient Golem buff to counteract Riftwalk's increasing Mana cost.
- Kassadin deals mostly magic damage. If he's doing well consider buying magic resist items like Mercury's Treads and Banshee's Veil.
- Each time Kassadin consecutively uses Riftwalk, he pays more and more mana. Keep this in mind as you chase him.
- It takes 6 spell casts for Kassadin's slow, Force Pulse, to become castable. If he levels up that ability, judiciously use your own skills while laning against him.
