LoL Champion Build Guides: Kassadin

Kassadin fires a void bolt, interrupting channel spells and dealing 65 / 95 / 125 / 155 / 185 (+70% of ability power) magic damage to the target enemy while granting himself a shield that absorbs 40 / 70 / 100 / 130 / 160 (+30% of ability power) magic damage for 1.5 seconds.

Passive: Kassadin's basic attacks draw energy from the void, dealing 20 (+10% of ability power) bonus magic damage.

Active: Kassadin charges his Nether Blade, causing his next basic attack to deal 70 / 95 / 120 / 145 / 170 (+80% of ability power) bonus magic damage and restore 4 / 4.5 / 5 / 5.5 / 6% of his missing mana (increased to 20 / 22.5 / 25 / 27.5 / 30% against champions).

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 80 / 105 / 130 / 155 / 180 (+80% of ability power) magic damage and slow enemies by 50 / 60 / 70 / 80 / 90 % in a cone in front of him for 1 second.

Kassadin teleports to a nearby location dealing 80 / 100 / 120 (+40% of ability power) (+2% of maximum mana) magic damage to surrounding enemy units. Additionally, each subsequent Riftwalk in the next 15 seconds costs double the amount of mana and deals 40 / 50 / 60 (+10% of ability power) (+1% of maximum mana) additional damage. The cost and damage can stack up to 4 times.
