Runaan's Hurricane bolts now affect champion-generated "On-hit" effects.
#And by "Champion-generated "On-Hit" effects" I suppose I mean "Champion Auto-Attack modifiers" to remove all confusion about "Oh but Cait's headshot!"
Sivir's Ricochet, Twitch's ult, Draven's Q, possibly. Abilities like that.
Does Hurricane become a good item? A must buy?
