Why this duo works
Nami's Surging Tides(P) helps Udyr reach targets, and Tidecaller's Blessing(E) adds damage and a slow to his attacks and spells. That extra access and sticking power complements Udyr's melee engage and first-attack stun.
Playing the duo
When Nami's abilities hit Udyr, Surging Tides(P) grants him movement speed; Tidal Wave(R) doubles that speed effect for allies it hits.
Tidecaller's Blessing(E) adds bonus magic damage and a slow to Udyr's attacks and spells, so it can strengthen the first attack that stuns with Blazing Stampede(E).
How to play as Nami
As Udyr closes on a gank, cast Tidecaller's Blessing(E) on him so Surging Tides(P) speeds his approach and his attack that stuns with Blazing Stampede(E) also applies bonus damage and a slow.
