Why this duo works
Soraka mains specifically call out Cataclysm plus Equinox: Jarvan's arena can keep a target inside Soraka's silence zone long enough for its root to trigger.
Playing the duo
Cataclysm(R) creates a bounded area around a target, while Equinox(E) silences enemies in a zone and roots those who remain until it expires.
How to play as Jarvan IV
After Cataclysm lands, signal Soraka to place Equinox over the trapped target so its silence can turn into a root before they leave the arena.
How to play as Soraka
Place Equinox over the target as Jarvan closes with Cataclysm; the arena gives your silence and delayed root time to hold them for his follow-up.
