Read from Jayce's seat: which stage windows this plan plays for against Gragas.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Jayce | You take Cannon Q and out-range Barrel Roll he has no Drunken Rage sustain or damage reduction yet, so free Shock Blast chip is yours. |
| Level 2 | Even / skill | He hits 2 and Drunken Rage's damage reduction plus Happy Hour's per-cast heal start eating your poke, but he still can't punish you from range. |
| Level 3 | Gragas | At 3 his Drunken Rage damage reduction and Body Slam come online he tanks the gate-Q and dashes in to brawl back. |
| Levels 4-5 | Gragas | He's tanky enough to walk through your poke now, and Body Slam closes the distance your Cannon Q is trying to keep. |
| Level 6 | Gragas | Explosive Cask (R) is a real spike you lack it knocks you into his range or under his tower, while your R is just the stance-swap. |
| First item | Gragas | His first-item Drunken Rage brawl survives your Cannon-Q-swap burst and stat-checks you, and his Cask zones your escape route. |
| Two+ items | Even / skill | It's an even AP brawl late spread your gate-Q poke, dodge the Cask pick, and Thundering Blow his dive off you to keep it a coinflip. |
Levels 1-2 are your window: take Cannon Q and chip him with Shock Blast every time he walks up to a minion, because before he has Drunken Rage (W) his Barrel Roll poke costs him health and Happy Hour only refills him when he actually casts. Do NOT sit in melee form here. The catch is his level 3: once he has Barrel Roll, Drunken Rage damage reduction and Body Slam (14s at rank 1), he can tank your accelerated gate-Q and dash on top of you, and his empowered auto out-trades you if you brawl. Land your poke, then back off on your passive move speed before he closes.
