Do

How to beat Jinx as Karthus: the early game

Levels 1-2 are yours: Jinx has no mobility and short Pow-Pow range, so you free-farm and land Lay Waste pokes while she can only last-hit cautiously. She cannot escape, so once your mana allows it, a Lay Waste rotation plus your support is a real kill threat rather than just poke. Cast at her step-ups and farm the rest. Keep Wall of Pain behind her instead of in front, so the retreat rather than the approach is the thing you are slowing.
