Track: Karma's W — Focused Resolve (12s cooldown). The root tether — break it with range or line of sight.
Read from Vex's seat: which stage windows this plan plays for against Karma.
This is Vex's own plan; across 2,680 pooled games the lane is leaning Vex.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Karma | Karma's RQ root out-ranges and out-pokes you at level 1 with her ult available. |
| Level 2 | Karma | At level 2 her Mantra poke and shield keep the sustained trade in her favor. |
| Level 3 | Even / skill | Through level 3 she still wins the poke war before your burst combo comes online. |
| Levels 4-5 | Even / skill | At level 4 your W+Q spike arrives and Karma's lack of a dash lets you punish her cooldowns. |
| Level 6 | Even / skill | Level 6 R Shadow Surge gives you an engage she can't escape without a blink. |
| First item | Even / skill | First item your Luden's burst breaks her E shield in a single rotation. |
| Two+ items | Even / skill | With two items you out-damage her sustain and R catches her every time. |
Levels 1-3 are Karma's: her RQ (Mantra-empowered Q) roots and detonates for heavy poke, and she can start with her ult so she out-ranges and out-sustains you immediately. Don't try to trade into a full Mantra window. Soak XP, dodge the Q, and track her Mantra cooldown so you know when she's vulnerable. Track Mantra is a 40s clock (34s late) and her passive refunds it on every hit — track it, not her.

Vex, slightly — a 53.55% win rate edge over 2,680 games; execution can flip it.
Mostly — Vex has a small statistical edge (53.55% win rate), but execution decides this lane far more than the pick does.
Not a hard counter — Vex has a slight edge (53.55% win rate), and play quality decides the rest.
Vex takes Electrocute on the Domination tree with Cheap Shot, Grisly Mementos and Ultimate Hunter, and Sorcery secondary (Manaflow Band and Transcendence) vs Karma.
Start Doran's Ring + 2 Health Potions and back for Lost Chapter (≈1300g) — the gloom goes sustainable. Build Luden's Companion first, then Shadowflame, with Sorcerer's Shoes / Mercury's Treads.
