[Champion Touch-Up] Kassadin, the Void Walker
Please note, these changes are what /I/ personally think would make a nice addition to Kassadin. I accept criticism whole-heartedly, but there is a line between criticism and flaming or trolling. Please stick to your criticism. Items that are in bold in the concept are things that I changed. I made this 'rework' mainly because obviously since the silence removal and the major nerf that Kassadin had recently experienced, he has been seen a whole lot less, and I feel this could bring up his playrate a bit. I don't expect this to get added, I make these and post them for fun.
Kassadin, the Void Walker
(Innate/Passive) Void Stone Kassadin takes 15% reduced magic damage and ignores unit collision.
(Q ability) Null Sphere Kassadin fires a ball of void energy at a target enemy, dealing 80/110/140/170/200(+70% AP) magic damage and giving Kassadin a spell-shield which will absorb 40/80/120/160/200(+20% AP) magic damage for 2 seconds and make him immune to crowd control for the duration.
(W ability) Nether Blade Passive: Kassadin's basic attacks will deal 20/25/30/35/40(+10% AP) bonus magic damage.
Active: Kassadin amplifies his next basic attack to deal 50/70/90/110/130(+65% AP)(+5% of maximum mana) as bonus magic damage. In addition, if Kassadin strikes an enemy champion, he will regain 10/15/20/25/30% of his missing mana.
(E ability) Force Pulse Passive: Each time a spell is used in Kassadin's vicinity, he will gain a stack of Force Pulse. Each stack will give him 5% additional magic resistance up to a maximum of 6 stacks.
Active: Kassadin strikes in a cone, slowing any enemy hit by 50/55/60/65/70% starting at .75 seconds. Each stack of Force Pulse will add .25 seconds to the slow up to a maximum of 2.25 seconds. Additionally, any enemy hit will be dealt 80/105/130/155/180(+70% AP) magic damage.
(R ability) Riftwalk Kassadin teleports to a nearby target location, dealing 80/100/120(+2% maximum mana)(+5% AP) magic damage upon arrival to all enemies within 150 units. Each subsequent Riftwalk within the next 20 seconds costs double the mana and deals bonus damage, stacking up to 4 times.
...and there you have it, my idea for a few Kassadin changes that could possibly bring up his rate of play a little bit. Leave all your criticism below if you'd like, positive and negative feedback welcomed.
