Robending is the hypothetical ability to control and manipulate rocks and earth. The best element for robending would be one that is abundant, strong, and easy to control. Some of the best elements for robending would be granite, basalt, and sandstone.
Granite is a very hard and durable rock that is resistant to weathering and erosion. It is also relatively easy to shape and control, making it a good choice for robending. Basalt is another hard and durable rock that is also very dense. This makes it a good choice for robending because it is difficult to move or break. Sandstone is a sedimentary rock that is composed of sand grains that have been cemented together. It is a relatively soft and porous rock, making it easy to shape and control. However, it is not as durable as granite or basalt, so it may not be as good a choice for robending in all situations.
