we'd like to give you some general information regarding the Halloween Items and NPC.
The NPC, Jack O' Lantern, will stay in Map1 of each Kingdom untill the 7th of November, after that he will be removed, so make sure to craft all your Halloween Boxes untill then. However, the Death Valley map is empty since the event ended.
On the Same day, November 7th, we will delete all Trick or Treat boxes that have not been opened, due to complains about bosses on all kinds of maps, especially map1 and low level maps.
On top of this, we noticed that quite a few of these Halloween Items (for example Costumes, mount skins) have been liked a lot and therefore, we will add them to our normal item mall roster after the end of their Item mall period as event items.
They will remain in the Item mall untill the 15th of november in their current state, after that they will be changed to match our current item mall items in stats (30 days + same stats) and will join our permanent roster.
