• The Ghostly Harvest Quest offers players level 45 and up a dangerous adventure in the frontiers. Speak with John Tobin on the Cotswold Bridge, Foa Muldisson outside the Jordheim North Gates, or Nera by the road in Mag Mell to begin the quest.
• Treat sellers have been spotted selling sugary confections inside Meath, Erikstaad, and Caerwent.
• The consignment merchants would like to show you their Halloween spirit! Pick up the merchant and place it back down on your house porch and he will change into a Halloween outfit for you!
• Be aware adventurers! Ghosts haunt the streets of your capital cities as the pumpkin moon rises!
• The horses you once rode have joined the spirit realm. (This affects stable and merchant horses only - not player controlled horses.)
• Something strange has happened to all of the puppies.
• The pumpkins have been carved into jack o' lanterns!
• A trio of crazy old women have been spotted selling costume potions inside Camelot, Jordheim, and Tir na Nog.
• The costume potions last 15 minutes each and come in a variety of flavors.
• They work best if you remove your helm and armor.
• You cannot digest another costume potion if you are transformed into any of the monster forms.
• The potions' magics are short-lived and the potions will be useless after the festivities end so don't horde them.
• Some of the potions allow you to take the form of the enemy, so don't be scared if you see some in your capital city or housing zones, it's just your realm mates playing dress up!
• The costumes and potions only work while you are in the capital cities or housing zones. You cannot use them outside of these zones and if you leave the zone while in costume, you will lose the effect.
