good day, why don’t you make items and materials and bosses with a time limit, after the time is up, they will be locked in Kyovasad or somew here else in the city, there are underground dungeons, why not put an npc into which you can put items, when the time is up, you click on the npc and you have the option of putting an item there that if someone buys the item, you will get gold for the item, and so it could also come with material for bare feet
the item should be modified as follows: the expiration time of the free trade option for the party, as well as the material
and now if the time runs out, it will be locked and you have two options: either we will give the item or the boss material to the npc, or we will keep it, this is a mechanic to bypass the sale of third parties in order to use the game potential, the possibility of selling the item ONLY for gold, not for real money!!ems such as a helmet, chest weapons, shoes, pants and materials for bare feet could be designed so that there is a review in this
