Sylph Rapier

A Sylph Rapier is a Light Blade found in Golden Sun: The Lost Age. It can be attained by giving a Sylph Feather to Sunshine; it is one of five items that may result randomly from the forging job. It can be bought for 10100 coins and sold for 7575. Being a light blade, it can be equipped by Isaac, Felix, Garet, Jenna, Ivan, and Piers.

The Sylph Rapier increases the wielder's attack by 124, and its normal attack always counts as an elemental physical attack, one where the damage from the attack is either increased or decreased based on how the user's Jupiter power compares to the target's Jupiter resistance (it is the only pure-element Jupiter-based weapon native to the second game, incidentally, with the Elven Rapier in Golden Sun being the other). Its Unleashed power is Mad Zephyr (Angry Zephyr in Japan), which adds 40 damage points to the resulting damage, is affected by the Jupiter element, and then has a chance to deal double damage after the attack bonus is applied. It has the standard base unleashing rate of 35%. Mad Zephyr appears as the wielder sending a series of four needles of light violet energy blasting into the target. If double damage is inflicted, far more needles are shot at a much higher rate of fire.

Like the Swift Sword in the first game, though to a lesser degree, the Sylph Rapier is a notable weapon due to having a massive damage spike. Though slightly inferior in raw attack and in unleash damage added to the Dracomace Jenna might be using at this point in the game, Mad Zephyr does far more damage than even Felix or Piers can do if its double-damage ability activates. As such, it is worth considering forging the weapon for Jenna's use during the late Eastern Sea and early Western Sea, particularly if she is made an Enchanter, Ascetic, or Ninja to boost her Jupiter power.

It is found again in Dark Dawn. It can be found while climbing Talon Peak.
