Read from Sion's seat: which stage windows this plan plays for against Rumble.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Sion | You are slow to charge Q at level 1, but Flamespitter is a 600-range cone — he has to walk into the arc, and a full knockup as he steps up wins the trade and burns his Scrap Shield. |
| Level 2 | Rumble | With Flamespitter and a harpoon both up he out-DPSes you in a sustained trade; Soul Furnace is online, but his cone keeps burning through the three seconds before you can detonate it. |
| Level 3 | Even / skill | Both kits are fully operational but the lane is contested: your W-shield neutralises one Flamespitter cycle, but his E-slow and overheat damage cancel your charge-Q threat at close range. |
| Levels 4-5 | Sion | Rumble's E-slow into Flamespitter sustain wins duels in the 4-5 lull — your Q takes too long to charge through the slow and his overheat autos out-damage your W-shield. |
| Level 6 | Rumble | Unstoppable Onslaught at 6 gives you a close-gap tool he cannot dodge without Flash; the all-in threat forces him to play back and stops the free Flamespitter poke cycle. |
| First item | Even / skill | Heartsteel's compounding stacks and your kill-HP passive mean Flamespitter ticks become negligible — you out-bulk his DoT and your W-shield absorbs enough to fight short trades freely. |
| Two+ items | Sion | Full HP-stacking wins the isolated 1v1: E shreds his armor, charged Q stuns him before Flamespitter cycles twice, and your zombie passive threatens follow-through damage even if he somehow trades even. |
Level 1 is yours if you can set up the charge — Flamespitter only reaches 600 units, so he has to walk into the Decimating Smash arc to use it, and a max-charge knockup as he steps up sends him back to tower with no way to punish you. Respect the walk-up angle though: if he gets his nose under yours before you finish charging, the cone burns through your body and he wins the damage race at that range. Take W at level 2 so his first real Flamespitter hits Soul Furnace rather than your health bar, then detonate the shield into him after absorbing the bulk of the burn — you trade magic for physical and come out ahead.
