I think it’s remained at 10 per day for Kingdom Passes? What they changed back in 6.9 was:
- Kingdom Passes will be changing to run only for 2 weeks.
- We are changing the Kingdom Pass Battlecrashers so they will have a flat chance to appear (i.e. They will no longer decrease in chance to appear the more players encounter them).
- Kingdom Pass Battlecrashers will now drop 2 Crowns instead of 1.
There may be more leeway on how many you need to find per day to complete the entire pass, but didn’t have the time to find a relevant post or calculate it right now.
