Why this duo works
Ashe's global Enchanted Crystal Arrow (R) can start a pick before Bel'Veth reaches the lane, and Bel'Veth can extend the stun with Above and Below (W)'s knock-up. That reliable first catch gives Bel'Veth time to close in and deal damage.
Playing the duo
Ashe can stun a target from anywhere on the map with Enchanted Crystal Arrow (R), while Bel'Veth's Above and Below (W) adds a knock-up and slow to extend the catch.
How to play as Bel'Veth
When Ashe's arrow connects, land Above and Below (W) as the stun ends to layer the knock-up, then use Royal Maelstrom (E) while the target is still controlled.
How to play as Ashe
Fire Enchanted Crystal Arrow (R) when Bel'Veth can follow from nearby or is already moving to the target; her W knock-up extends the catch long enough for both of you to arrive.
