Read from Gragas's seat: which stage windows this plan plays for against Kassadin.
This is Gragas's own plan; across 344 pooled games the lane is leaning Kassadin.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | You have one ability so Happy Hour barely heals, and his Void Stone reduction blunts your poke — neither of you wins level 1, so just farm. |
| Level 2 | Gragas | Q+W gives you a W-empowered sustain trade his Null Sphere chip can't match, and with no Riftwalk yet he can't punish you back. |
| Level 3 | Even / skill | Your combo isn't fully online and your cooldowns are long, but a pre-6 Kassadin still can't out-trade or escape a clean Body Slam stun — call it even. |
| Levels 4-5 | Gragas | W max plus Happy Hour out-sustains his Null Sphere poke and lets you bully an immobile Kassadin off the wave. |
| Level 6 | Even / skill | E-stun into W-auto-Q plus Explosive Cask is a real all-in, and you can angle the Cask to knock him away from tower before his first Riftwalk is worth the mana. |
| First item | Gragas | Your Riftmaker/Rocketbelt burst can still delete him on Rod of Ages, but his Seraph's timing is close behind — whoever hits their item first owns the trade, so it's a knife's edge. |
| Two+ items | Kassadin | Rod of Ages plus Seraph's and stacked Riftwalk let him blink onto you and Null Sphere your combo while Void Stone eats your burst — he out-scales and you can't pin him. |
Level 1 is a wash: you have one ability so Happy Hour barely triggers, and his Void Stone magic-damage reduction blunts what little poke you have, so just last-hit. At level 2 take Q+W: Null Sphere shields him against magic, so poke through the shield rather than around it, and his chip can't out-sustain your W-empowered auto plus Happy Hour. He has no Riftwalk until 6, so if you land Body Slam (E) into a stun you get a free W-auto-Q before he Flashes — don't whiff it chasing, because E is down 14s at rank 1.
