Hush hostage no more! A hotfix has gone out to the Runeterra servers to fix spell casting abuse.

Hey folks, we just hotfixed out a cap of 15 for casts of the same spell in a single round. This is a quick fix for infinite loop abuse we've seen, with more general turn timer updates to follow later this year. Thanks for the reports, and please always be excellent to each other.
