How to use Tesla Cannon?
In Fallout 4, the Tesla Cannon is an area-of-effect energy weapon that can damage enemies within the blast radius. The standard shot from this weapon is a burst of blue, crackling lightning, creating an energy AOE. Furthermore, you can craft a Tesla-Beaton Assembly mod that will change both the color of the energy, as well as the type of effect. You will fire yellow energy at a single target with the Tesla-Beaton Assembly. Then, that energy stream will burst through the target and automatically chain to another nearby target.
However, to create the Tesla Cannon mods, you will need to have leveled your character and their skills quite a bit. Consequently, to max this weapon out and experience its full potential, you’ll have to have very high Intelligence and a Science Rank 4. This is a perfect weapon for thePower Armor build, which uses the Heavy Gunner perk. With four points invested, this Tesla Cannon will stagger enemies and, if not outright, kill them.
