Track: Viktor's W — Gravity Field (17–13s cooldown). The stun zone owns every all-in — walk out the moment it drops or fight outside it.
Read from Kassadin's seat: which stage windows this plan plays for against Viktor.
This is Kassadin's own plan; across 6,041 pooled games the lane is leaning Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Viktor's zone control and empowered autos punish your melee approach before you have mobility, so early favors him. |
| Level 2 | Even / skill | His Siphon Power stacking damage keeps compounding the longer the poke-heavy lane continues. |
| Level 3 | Viktor | Level 3 stays his — Gravity Field plus Hextech Ray zones the farm walk, and Force Pulse has to charge off spells cast near you before it fires. |
| Levels 4-5 | Viktor | Siphon Power is down to 7 seconds by rank 3 and shields him through your step-up, so these levels stay comfortably his. |
| Level 6 | Kassadin | Riftwalk lands and Null Sphere interrupts his Arcane Storm channel, so the level 6 kill threat flips to you. |
| First item | Even / skill | First item is skill: blink-strings start chunking, but Gravity Field still catches a blink that lands inside it. |
| Two+ items | Kassadin | Full build your mobility over his stationary kit is a clear scaling advantage, so late favors you. |
Viktor's Gravity Field zoning and Siphon Power empowered autos punish your melee trade pattern before you have mobility to dodge his AoE, so you're stuck conceding lane control and CS while he scales safely behind his zone control tools. Viktor's Siphon Power buff plus Gravity Field zone control lock down your melee approach, and every empowered auto punishes you for stepping up to farm.
