Kassadin Changes

Patch 26.11

buff

Our Void Walker has been limping around the Rift more than blinking. Stackable tear items have provided an additional cool late-game fantasy option besides pure AP, but his early game has been tougher than usual (in part due to our mid quest adjustment). These changes should help his laning, both in farming and trading.

Null Sphere

  • Cooldown reduced to 9/8.5/8/7.5/7 seconds from 10/9.5/9/8.5/8.

Nether Blade

  • Passive base damage increased to 25 from 20.

Patch 26.4

nerf

Kassadin's been having a great time now that he's able to stack multiple Tear of the Goddess items. Seriously, get on the Seraph's + Muramana train! But because this newfound power has taken him over the edge, we need to appropriately balance him. We want to preserve his high late game damage and mobile scaling fantasy, but we want to balance those strengths with appropriate weaknesses once he gets there.
