What is diablo 3 empowered rift?

Diablo 3 Empowered Rift is a game mode in which players can spend gold to increase the amount of rewards they receive from completing greater rifts. In order to enter an empowered greater rift, players must first complete a regular greater rift within the allotted time limit. Once they have done so, they can choose to empower that rift by spending gold to receive a bonus Rift Keystone. This gives them an extra chance to complete the rift and earn additional rewards.

However, if the empowered rift is not successfully completed within the time limit, the extra Keystone will be lost along with the gold spent to empower it. This mode is popular among players who are looking to farm for legendary items and materials, as the increased rewards give them a better chance of obtaining rare equipment and upgrading their character's abilities. Empowered Rift is available in both solo and multiplayer mode, allowing players to play with their friends or join a public game to compete for rewards and climb the leaderboards.
