Why this duo works
Warwick's R gives Diana a reliable target to follow: her Q mark resets Lunar Rush(E), letting her join the dive and add burst while he holds the target. Once Warwick's suppression ends, Diana can use Moonfall(R) on nearby enemies for area damage; Warwick players value this kind of follow-up damage and crowd control after his engage.
Playing the duo
Warwick's Infinite Duress(R) suppresses one target for up to 1.5 seconds, while Diana's Crescent Strike(Q) marks a target so Lunar Rush(E) resets when she dashes to them.
Diana's Moonfall(R) draws nearby enemies toward her and deals more damage for each additional champion pulled, adding area follow-up around Warwick's single-target engage.
How to play as Diana
When Warwick finds an engage, hit Crescent Strike(Q) on his target and use the Moonlight reset on Lunar Rush(E) to follow into range. Let his Infinite Duress(R) suppression finish before using Moonfall(R) on nearby enemies for its multi-target damage.
