A jabberwock can burble every 1d4 rounds. This blast of strange noises and shouted nonsense in the various languages known to the jabberwock (and invariably some languages it doesn't know) affects all creatures within a 60-foot-radius spread - these creatures must make a Wand save or become confused for 1d4 rounds. Alternatively, the jabberwock can focus its burble attack to create a 60-foot line of sonic energy that deals 4d8 sonic damage (Breath save for half). The confusion effect is mindaffecting; both are sonic effects.
