Festivult

Throughout the Festivult event held in holiday season, every treasure chest in the game has a chance of dropping festival coins in addition to the usual treasure. Coins can be exchanged for seasonal items. Coins and rewards are unbound.

The Festivult Tradition (lore)
''Since ancient times, the folk of Eberron have observed Long Shadows during these chill weeks of the month of Vult (December) -- a grim season when the power of the Shadow, god of the Dark Six, is at its strongest. Dire magic gathers in dusky corners, and evil stalks the night in a thousand guises. The Coin Lords have determined that the terror of Long Shadows must end! To this end, they devised the festival as a celebration to drive evil out of the city. Instead of cowering from the Shadow, citizens are encouraged to exchange gifts with their adventuring partners and loved ones. And by slaying the monsters who threaten the city's well-being, they may collect festival coins to demonstrate their dauntless spirit in the face of Long Shadows and the Dark Six!''

''The planes are vast and mysterious, and we can never predict how their alignment will impact the magically imbued gifts of Festivult. Each year the Festivult gifts are imbued with a different magical power depending on what planes are in alignment. So if you have some left-over goodies from Festivults past, beware, friends - those treats may not bring the same affects as before!''

Reward items
The item effects are based on Planes of Eberron (Eberron wiki link), and their alignment will have impact on them.

Each year the Festivult Cookies and Cakes are imbued with a different effect depending on what planes are in alignment. Any left-over Cakes and Cookies, will have their effects retroactively change.

Cookie Jar
There are 30+ types of Cookies and Cakes, it is recommended to turn all coins in on one character (possibly a mule designated for event items only) to prevent a major inventory mess. A Cookie Jar can hold all Cookies and Cakes until max stack size is reach for the cookie type, in one inventory slot. The cookie jar is a DDO Store item.

Cookie Jars are. The Large Cookie Jar will grow quite heavy eventually, so it may not be good idea to carry these around especially on low-strength characters such as finesse/halfling builds and casters. Make sure you are on the right character before making purchase.
 * The Lloth, The Spider Queen cookie is obtained from the Midwinter Festival as a Mote turn in reward rather than the Jester coin turn in. It still goes into the Cookie Jar.
