This is from Cookie Run Updates! (https://twitter.com/cookierunupdate ) meaning that if the highest you've gotten is Hero Level V, you'll get a certificate (or trophy) treasure of 40% chance of obtaining 1. I haven't played the Kakao version before the Wrath of the Dragon so I don't have one (sadly), but I guess it will be much like the ones given before with a slightly higher chance of obtaining 1 with higher levels.
