During the endgame content of Lost Ark, you will come across a ton of events to do and collect resources from. Of these are an event called the Platinum Fields that lets you farm for the best possible Trade Skill resources without spending all of your stamina. But, how exactly do you unlock these events?
Well, like many of the other events like the Cube, you need to get a hold of a particular ticket. For the Platinum Fields, you need to find an item called Entrance Ticket: Platinum Field (Bound). You can find one of these as you do random Trade Skills, but you must be patient, as the drop rate is very low.
Once you find one of these tickets, you will automatically have access to two different Platinum Fields maps that you can collect resources from. You will need one ticket each time you want to enter the Platinum Fields. Considering that they are difficult to find, make sure to use each one carefully!
