Fiery Dragon Sword

Description
The Fiery Dragon Sword (commonly abbreviated to FDS), like its cousin the Icy Dragon Sword, is a popular sword mainly prized for its style. It is quite an impressive sight with its flaming blade with only two twisted "filaments" as a solid core. Early on it can be admired in the hands of several NPCs, most notably Prince Rurik. Later, some monsters also carry it (e.g. Centaurs).

All Fiery Dragon Swords carry a Fiery hilt upgrade that cannot be removed by any other upgrade. It must have this upgrade, so it is not popular to strategy-minded players, who prefer other popular swords like Fellblades as targets for their weapon upgrades.

Location
Fiery Dragon Swords are a random drop. They appear in high-level areas, apparently from the Crystal Desert onwards - although they are a rare drop in a few preceding areas (e.g. White Mantle Justiciars are known to carry them).

Dye
Applying dye to a Fiery Dragon Sword affects only the hilt. Dye does not change the color of the flame. The only way to get a different colored flame is to get an Icy Dragon Sword, which has a blue flame.
