This calculator helps you estimate the catch rate for specific enemies in Genshin Impact using the "Gen IV" (Generation IV) mechanics, as commonly understood and implemented by the community. It takes into account various factors that influence your success when using the Randomized Scrambler gadget.
Common (1 Star)
Uncommon (2 Star)
Rare (3 Star)
Elite (4 Star)
Boss (5 Star – e.g., weekly bosses)

// For Gen IV, the gadget primarily reduces enemy resistance or increases your effectiveness.
// Let's model it as a direct boost to the catch rate, scaled by stacks.
