How to play as Naafiri

Keep The Call of the Pack(W) available when Sejuani has a clear Glacial Prison(R) line; dodging the projectile denies the long-range stun that can set up her follow-up control.

If Sejuani's Frost Armor(P) is active, avoid forcing a slow-based chase; let the armor window break and look for a clean angle after her out-of-combat resistances fade.

Sejuani's Glacial Prison(R) stuns the first champion it hits and sets up further Frost stacks, while Naafiri's W can briefly become untargetable to avoid that projectile if timed before impact.
