• Netherblade has been redesigned:
  • Passive: the mana drain component removed and replaced with a flat 4/8/12/16/20 mana restore on hit. This effect returns triple the mana against champions.
  • Active: Kassadin gains 7/15/25/38/50 Armor Penetration for 5 seconds. 15 second cooldown. 30/40/50/60/70 mana cost. Activating this ability counts as a spell cast for the purposes of Force Pulse.
• Null Sphere projectile speed increased to 1150 from 900
• Void Stone (Passive)
  • The attack speed effect from Void Stone has been changed so that it stacks and renews instead of replaces on spell impact. This change will result in Kassadin gaining significantly more attack speed, and keeping it for a longer duration on average.

• Void Stone now applies an additive attack speed boost, rather than multiplicative
