Mastery Tree Is Outdated
WARNING: These masteries are still using the old tree and have not been updated to the new tree by the guide author. As such, they will be different than the masteries you see in-game.
Welcome to my Build of Kassadin:The Void Walker. This champion is my favorite caster, to me his is better than any caster in the game. He does a lot of damage fast but can also fight up close with his Nether Blade. He is just amazing and does to much damage even without being fed.
For Marks I get magic Penetration Because he does burst damage so if you have magic penetration you can do more damage fast especially with the combination of the Abyssal scepter Which takes away their Magic Resistence.
For Seals i Take cooldown because his skills already have low cooldowns so if you have more than you can spam spells even more to do more damage.
Finally for Glyphs i get Mana Regeneration Because even after you get an archangels staff you use a lot of mana so extra regen can help a lot :)
For Quints i take even more magic penetration for the same reason :)
His Four Skills are-
His Q-Null Sphere
Kassadin fires a void bolt dealing 80 / 130 / 180 / 230 / 280 (+70% of ability power) magic damage and silencing the target for 1 / 1.4 / 1.8 / 2.2 / 2.6 seconds.
His W--Nether Blade
Passive: Kassadin's melee attacks draw energy from the void, restoring 4 / 8 / 12 / 16 / 20 mana each hit. If this effect is triggered from attacking a champion the amount of mana restored is tripled.
Active: Kassadin charges his nether blade, gaining 7 / 15 / 25 / 38 / 50 armor penetration for 5 seconds.
His E--Force Pulse
Kassadin draws energy from spells cast in his vicinity, gaining a charge whenever a spell is cast near him. Upon reaching 6 charges, Kassadin can use Force Pulse to deal 60 / 120 / 180 / 240 / 300 (+80% of ability power) magic damage and slow enemies by 30 / 35 / 40 / 45 / 50% in a cone in front of him for 3 seconds.
Kassadin teleports to a nearby location dealing 60 / 90 / 120 (+40% of ability power) magic damage to surrounding enemy units. Additionally, each subsequent Riftwalk in the next 7 seconds costs 100 additional mana and deals 60 / 90 / 120 additional damage.
His Passive-- Weapon Mastery
Kassadin takes 15% reduced magic damage and transforms this damage into bonus attack speed.
I get Null sphere and Force Pulse first because they are what do his damage. Of course getting Rift Walk when you can for Catching ability and also escaping. Then nether blade is also good for the mana regen and Penetration. Then from then you do work. Cant be stopped really without a stun because after you get the Abyssal scepter you do too much burst damage to squishy cares and to tanks you do still a considerable amount of damage.
