Sylph Feather

Analysis
Sylph Feather-crafted equipment is generally most useful during the exploration of the Great Eastern Sea. However, Lemuria's Lucky Medal Fountain offers stronger equipment. Thus, individual Sylph Feathers found in Tundaria Tower and Ankohl Ruins should be forged as soon as possible. The Floating Hat is one of the strongest pieces of headwear available prior to Lemuria, though its bonus to Jupiter Resistance is overlooked due to a lack of Jupiter-oriented opponents. The Aerial Gloves provide a useful bonus to Jupiter Power. While lower than the Leda's Bracelet, the Aerial Gloves are still useful for Felix and Piers, should they be utilizing Jupiter-based offenses. Finally, the Sylph Rapier, while granting a slightly lower Attack bonus, has the potential to deal high amounts of damage due to its chance of doubling dealt damage.
