How to play as Volibear

Watch Rengar's Ferocity before using Thundering Smash to start a duel; if he has an empowered cast ready, bait out Battle Roar first, then use Q while his crowd-control cleanse is unavailable.

If you expect an early Rengar invade, keep Sky Splitter available until he commits instead of letting its shield expire while he waits in a nearby brush; check the approach with vision before starting the camp. (Unverified: no source confirms this note.)

At maximum Ferocity, Rengar's Battle Roar removes crowd control, so he can cleanse Volibear's Thundering Smash stun if he still has an empowered cast available.
