Yes, starting at a modest 10,000 NP, you will have to pay to reroll your weekly item. That being said, we have made a few improvements to justify this change:
1. You are not limited to the amount of rerolls in a day, the only limit is how much NP you have.
2. You no longer have to sacrifice your streak to reroll your item and you can reroll at any point until you have completed your last quest on the final day.
3. Once you have completed the final quest on the last day of your streak, you will be locked into claiming the prize that is currently active.
4. Any item you skip while rerolling will not appear again until you have cycled through the entire prize pool.
5. Once you complete a weekly streak, the NP cost will reset to 10,000 NP!
