The Featherblade is one of the many weapons that can be acquired in the Frontier. The Featherblade can be purchased from Looney Lenny the Hedgeknight in Great Pine Forest at a price of 220,000 gold. Other than that, there are no alternative methods that players can do to get the Featherblade.
In appearance, its hilts and grip appears to be made out of forged metal with sky-based themes; white, black, and yellow. The blade itself appears to resemble similar to that of a lint-covered feather quill.
The normal swing-based attack of the Featherblade consumes around 1-3 stamina points per swing. Each slash lasts for approximately 2 seconds before another swing can be unleashed.
The special ability of the Featherblade is titled 'Glide Spin', which, upon activation, results in the players to move forward as they swing their blade while spinning and levitating towards their opponents. The special ability lasts for 3 seconds and its cooldown lasts for about 10 seconds before it can be used again.
- A sword similar to the Featherblade can be found hanging in the Red Ogre Inn. These weapons have identical models, but slightly different color schemes.
- The Featherblade is one of the few weapons that were not affected by the Otherworld Update or the 1.10 (Fishing) Update.
- During the Balance Update [v1.31], the Featherblade's base damage was increased from 185 to 231 points.
