A pair of changes are coming to the Marvel Machine that will take effect with its next run, currently planned for late summer 2025. These changes are:

• Newly purchased Marvels can be used up to 90 days after the end of the event, and will expire after that point.
  
• Item codes obtained from used Marvels will remain available to be redeemed in-game for 1 year after being acquired from the Marvel Machine.
  

Maplers with remaining Marvels purchased from previous runs of the event will still be able to use them during future Marvel Machine runs and they will not expire. Those pre-existing Marvels will be expended before any newly purchased Marvels are used.

Thank you,
