In the build, 2 blue Archon crystals are used to increase the maximum energy, 2 green crystals for the number of corrosion stacks, and 1 yellow crystal for maximum energy upon appearance.
I play with Grimuar for emergency energy recovery. The essence of playing with Grimuar is that the energy from the mod (Call of Kset) won’t work while your streaming ability is active. Therefore, you need to turn off the 4th ability if you want to restore energy.
Of all the companions, I chose Diriga-https://overframe.gg/build/745942/
build for the Excalibur sword- https://overframe.gg/build/745939/
