This is Varus's own plan; across 712 pooled games the lane is leaning Karthus.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Varus | Karthus has no auto range or mobility, so your Q out-pokes his Lay Waste at level 1. |
| Level 2 | Varus | At level 2 you punish his stationary delayed casts with charged Q behind minions. |
| Level 3 | Varus | Level 3 lets you stack Blight and detonate Q every time he walks up to farm. |
| Levels 4-5 | Varus | Through 4-5 your range and sustain keep him pinned with no way to trade back. |
| Level 6 | Varus | Your level 6 R roots his dash-less body for a free all-in he can't escape. |
| First item | Varus | At one item you out-DPS and out-range a self-slowing mage with no mobility. |
| Two+ items | Varus | In fights you delete a stationary backline target with only Requiem to respect. |
You crush the level 1-2 lane: Karthus has no auto range and no mobility, so your Q out-pokes his Lay Waste and he can't trade back. Harass him off every CS and stack Blight when he steps up. He has no reach and no escape, so out-poke his Lay Waste from a distance he cannot answer and harass him off the wave. Stack blight on his casting animations. Keep Hail of Arrows outside the Defile ring, and take the plate on the crash rather than diving a champion who dies usefully.
