When the quest is released but there is a full inventory, it will be devote the bank. But if your bank is also full, the Wise Old Man could keep it and will hand back it without any demand. But you have to pay attention that if you receive multiple sets while your current inventory and bank are generally both full, you can only get one challenge and the set is usually worn and unequipped for two main times. So, remember to claim your current set before another set is shipped to the Wise Old Man.
That is because each time a new quest is offered, players cannot wear your cape and hood again and they'll automatically be unequipped unless the ball player finishes the new journey. Hurry up to get quest points and cilck here to buy the cheapest RS Silver.
