Spin Rewards & Expected Value

After 120 spins, the estimated average yield is approximately 180.76 hero shards (about 65.76 from random spin drops + 115 guaranteed from milestones). Actual results vary due to RNG. To reach 5 stars (1,075 shards total: 10 to activate + 1,065 to max), a player typically needs around 6 full events.
