Unfortunately, in most games like RAID: Shadow Legends, once you upgrade a character’s star level, there's no official way to downgrade or remove a star to make them eligible for fusion or sacrifice. This means that if you've accidentally upgraded Beast Wrestler to 5 stars, you won't be able to use him for the Harvest Jack fusion anymore and will need to find or build a new 4-star version. It’s a frustrating mistake many players encounter, so double-checking before upgrades is crucial. Think of it like choosing a high-performance server in Low Latency Cloud Games —once you're committed to that fast, optimized route, there's no going back to a slower option without starting over.
