Greater Rifts - XP table

The table below shows the amount of experience, gold and shards we receive for completing a given Greater Rift level. In addition, it also presents the amount of gold required to empower the rift. In the first column you can see the approximate amount of experience we actually get for completing the GR, along with the experience for killed monsters. This number is an average value based on several passes of a given GR level and may vary depending on the type of monster in a given GR. Due to the fact that most of the time during the season is spent at higher levels, GR are written every one level from 90. Below are the values from GR 14 every 5 - levels most commonly used when leveling legendary gems using empowered GR. It is easy to calculate the leveling of one legendary gem to level 100 costs 334 122 787 gold (502 360 000 for empowerment - 168 237 213 obtained for completing the GR), and during leveling we get 4931 shards.
