To get a Greater Rift Keystone (GRK), you need to defeat a Rift Guardian in a normal Nephalem Rift. These keystones are essential for opening Greater Rifts, which are a higher level of challenge and offer greater rewards.
When you reach level 70 in Diablo III, you gain access to Nephalem Rifts, which are randomized dungeons filled with hordes of monsters. As you make your way through these rifts, you will encounter various enemies and collect loot along the way. The goal is to clear the rift and defeat the Rift Guardian, who awaits you at the end.
Once you defeat the Rift Guardian, there is a chance that they will drop a Greater Rift Keystone. The drop rate can vary, but on higher difficulty levels, you have a better chance of obtaining multiple keystones at once. It’s not uncommon to see two or even three keystones dropping from a single Rift Guardian in higher difficulty settings.
Now, it’s worth noting that the drop rate of Greater Rift Keystones is not guaranteed. Sometimes you may defeat a Rift Guardian and not receive a keystone. It’s all part of the game’s RNG (random number generator) mechanics, which add an element of uncertainty and excitement to the loot hunting experience.
To use a Greater Rift Keystone, you need to find a Nephalem Obelisk in town or in the world. Interacting with the obelisk will open a menu where you can select the option to open a Greater Rift. Once you’ve chosen to do so, you will be transported to a special Greater Rift level, which is separate from the regular game world.
Greater Rifts are timed challenges, where you aim to clear floors filled with enemies as quickly as possible. The difficulty of these rifts scales infinitely, allowing you to push your character’s limits and strive for higher levels of difficulty and better rewards.
In summary, to get a Greater Rift Keystone, you need to defeat a Rift Guardian in a normal Nephalem Rift. The drop rate of keystones is not guaranteed, but it increases on higher difficulty levels. Once you have a keystone, you can use it at a Nephalem Obelisk to open a Greater Rift and embark on a greater challenge.
