Kassadin rework idea
Passive: Voidheart: Through kassadin flows the power of the void, enabling him to pass through units. When kassadin damages an enemy, they are afflicted with 'conduit'
Q: Void bolt: Kassadin lobs a powerful voidbolt, dealing 80/120/160/200/240+0.4total AD+0.6AP as magic damage. 50/60/70/80/90% of the damage will be spread to nearby enemies afflicted with conduit, with the first target taking damage again. Range: 1200 Cost: 80 mana Cooldown: 10 seconds
W: Unchanged
E: Violet light Kassadin bathes a target in void energies, dealing 5/7/9/12/14% of their max health. If this ability kills its target, it leaves behind a cloud that deals 1% max HP damage per half second, afflicts enemies with conduit and lasts 15 seconds. If this ability kills an enemy champion, tendrils will attempt to attach to enemies within 600 range and root for 3 seconds after two seconds of being attached. Cost: 100 mana Cooldown: 12 seconds Range: 500
R: Riftwalk: Toggle: Kassadin ignores terrain and gains 10/20/30% movement speed. Cost: 50% of current mana, 10/8/6% of maximum mana per second. Cooldown: 0
, its mana costs arent actually very high. I mean the 50% current is, but when your mana pool is so high AND 25% of it is getting refunded, its negligable for small engagements. you dont want the ult to be on all the time, you want to use it to set up cut offs in the jungle.
