Read from Senna's seat: which stage windows this plan plays for against Heimerdinger.
This is Senna's own plan; across 1,777 pooled games the lane is leaning Senna.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Senna | Level 1 you have autos and W-Q burst before any turret exists, so the lane is yours. |
| Level 2 | Senna | Level 2 you still out-trade him with support CC before the grid forms. |
| Level 3 | Senna | Level 3 remains your window while he's only placed one turret. |
| Levels 4-5 | Heimerdinger | Levels 4-5 both turrets are up and the wall of DPS out-zones your slow autos. |
| Level 6 | Heimerdinger | Level 6 UPGRADE!!! supercharges his turrets and your R offers no dodge to a static grid. |
| First item | Heimerdinger | At one item his turret plus rocket damage still out-trades your soul stacks in lane. |
| Two+ items | Heimerdinger | At two-plus items his zone control remains the lane-phase king even as your global scaling closes the gap. |
Levels 1-2 are your best trading windows: Heimer has no turret wall yet, so W-Q-auto with support CC can genuinely chunk him before he sets up. Contest melee minions and shove the first wave to deny his turret placement rhythm. Your best trading window is before the nest exists, so contest the melee minions early and use the root plus your support while he only has one turret down. Piercing Darkness heals through the chip afterwards. Once the wall is built, stop stepping up and collect souls at range instead.
