The Deathly Galeslash's head resembles a Deadly Nadder while its body is almost identical to a Stormcutter. However, overall, they have the built of a Deadly Nadder covered with piercing poisonous spines, with added physical characteristics of the Stormcutter, most notably the two pairs of wings and three frills on each side of their heads, as well as a three-finned tail. As a hybrid, this dragon's scales are a mix between its parental species.
Deathy Galeslashes are able to breathe bright orange magnesium fire, which they inherited from the Deadly Nadder part of the family. The fire comes out in a tornado-like shape, trait which they inherited from the Stormcutter part of the family.
Air Current Detection
Hah! Stupid dragon still has a blind spot — OUCH![src]
— Tuffnut, finding out a Galeslash can detect air current
Using their four wings, Deathly Galeslashes are able to detect changes in the air currents. This allows them to use the currents to their advantage in flight.
Did you know that a Galeslash can see a yak's eye from 1000 feet?![src]
The Deathly Galeslash's behavior falls somewhere in between that of each parent; they are intelligent, very active, and playing fetch with them keeps them entertained. They also tend to be aloof and can be intractable if their respect is not earned.
Deathly Galeslashes are so intelligent, that they tend to prefer strategies that confuse their opponents. Some individuals like Copsekeep have even played Maces and Talons.
Incredibly intelligent, yet steely and aloof, the Frigid Galeslash makes training an exercise in patience. They key to befriending this dragon is for the rider wait quietly in the cold nearby, sometimes for hours on end. Eventually, the Galeslash learns to respect the rider, and its heart thaws enough to allow bonding to begin.
Deathly Galeslashes require respect before they decide to submit to a rider, usually through feats of strength or resilience. They are also a bit high maintenance due to their intelligence and activity levels.
The Deathly Galeslash was first introduced in this game, along with many other dragon hybrids. The only way a player can obtain a Deathly Galeslash is by breeding a Deadly Nadder and a Stormcutter in the Breedery.
A brand of newly released merchandise, Legends Evolved lists this dragon as Deadly Galewind instead of Deathly Galeslash.
