Lee Sin vs Cho'Gath

For the Insec, land Sonic Wave (Q), reach the target, ward behind them and jump to it with Safeguard (W): Dragon's Rage (R) kicks them toward your team.

Wait until your target has lost health before casting Resonating Strike (Q): its damage scales with missing health, and you have 3 seconds to cast it.

Cast Safeguard (W) on an ally, minions included, or on a ward to dodge or escape: it has a 7-second cooldown and also shields the targeted allied champion.

Look for invades, ganks and objectives early on: Lee Sin is strongest early, and his impact drops once the others have their items.

Keep moving against him: Rupture (Q) strikes an area on the ground, and an enemy standing still takes a knock-up, damage and a slow.

Punish him when he goes for last hits: Carnivore (passive) restores health and mana for each unit he kills, and he lasts a long time in lane if you let him farm.

If you have range, keep your distance: his kit has no dash, only the slows from Rupture (Q) and Vorpal Spikes (E).

Don't stay in melee range at low health when Feast (R) is up: its true damage ignores your resistances, even if you're a tank.
