How to play as Vex

Keep Doom 'n Gloom's fear ready when Ahri has Spirit Rush (R) charges; her dashes can trigger your passive mark, and the fear can stop her follow-up.

Ahri's Spirit Rush (R) is a series of dashes, while Vex's Doom 'n Gloom passive marks nearby enemies when they dash and can empower her next ability to fear.

Ahri's Charm(E) immediately stops movement abilities, while Vex must recast Shadow Surge(R) to dash to its marked target; Ahri can interrupt that approach with her charm.

How to play as Ahri

Watch Vex's fear indicator: when it is ready, use Fox-Fire (W) to sidestep her Q or E and trade after she spends the empowered spell.
