Rammus vs Naafiri

Engage with Powerball (Q): your speed builds while you roll, and the impact knocks back and slows enemies around your target.

Cast Defensive Ball Curl (W) when you're being hit by autos: you gain armor and magic resist, and each attack returns magic damage to its attacker.

Cast Frenzying Taunt (E) during Defensive Ball Curl (W): forced to attack you, your target takes damage with every auto.

Cast Soaring Slam (R) during Powerball (Q): enemies in the center of the area also take a knock-up, and your speed extends the leap's range.

Dodge Darkin Daggers (Q): her pack leaps onto the first champion hit, and the second dagger hits harder if you're already bleeding.

If you have AoE spells, hit her pack too: each packmate killed lowers her damage. Do it before Eviscerate (E) calls them back and heals them.

Save your targeted spells for after The Call of the Pack (W): for a brief moment, she and her pack are untargetable.

Avoid crossing the map alone against her: Hounds' Pursuit (R) lets her dash onto a champion from range, and a takedown lets her recast it.
