The Billed Cap was devised to keep the sun out of an Aisling's eyes while enjoying themselves in Paradise Beach. It is a vanity item that can be worn over the top of any functional headgear. The Billed cap is also unique in that it is the only vanity item that offers additional bonuses other than just it's appearance. You will find a Billed Cap inside the Sun Protection package given out by Francis during the Paradise Beach event. As the cap is non-transferable, this is the only way to acquire one.
The Billed Cap offers a boost of 1,000 HP and 1,000 MP making it marginally useful depending on your bases.
This is the Billed Cap as it appears on a female and male Aisling.
