The latest craze brought by ArenaNet in December 2005. IDS is short for Icy
Dragon Sword. An Icy Dragon Sword is like a Fiery Dragon Sword, the only
differences are that it has a blue flame, black hilt, and deals cold damage.

These elusive swords can be only found in one place in the game. They are
found off the Ice Imps in Lyssa’s Cave in Mineral Springs. Lyssa’s Cave is on
the east side of Mineral Springs, so if you follow the paths, you’ll
eventually reach it. You will face heavy resistance of Avicara if you fight,
so come well-prepared.
