CHALLENGE: Highest Mastery Score for RP

Each champion can have a mastery level of up to 7. As of patch 6.23, there are 133 champions. The highest mastery score possible at this time is 931.

If anybody manages to reach the highest possible mastery score (number will change with new champions), I will gift you 15,000 RP.

I am really interested to see someone have this number, similar to having your odometer go from 999,999 to a reset. I'll just be in awe of such a perfect digit. The victor will not only win this prize, but win a mastery of all champions!
