The Wind Blows is the fourth stage in Squishy Cave. It is also the first stage in Stories of Legend that Owlbrow appears in.
Gory Black appears as support. Shortly after Gory Black's appearance, Owlbrow appears. There will be no boss wave in this stage. When the base is hit, several Owlbrows will appear at the same time.
You can choose to lure the Owlbrow to your base and kill all of them with Bahamut Cat or you can stall them while they are at the base.
