Arc

"A spark can give life...or take it."

- Grimoire.

Arc is one of several known manifestations of the Light, along with Solar and Void. It is related to electricity and electromagnetism, and can be wielded by Guardians to generate lightning bolts and other electromagnetic phenomena. It is also one of five classes of elemental damage common to all Guardian weapons.

Overview
"Arc energy's not just electricity. Lot more finicky than that. Fission."

- Banshee-44

Many of the Golden Age technologies of Humanity possesses circuitry, generators that run on Arc Energy, including weapons as well as tech that produces holograms. Vex are known to have a hindrance to exposure to Arc Energy, although this would be if they weren’t attempting to harness it. Arc is even found in the weather system itself. Arc energy can be found in Dark Ether with how the Screebs and Abominations use their attacks. Concentrated Arc can even distort space, and enough of it can even hinder Transmat usage.

Subclasses
Striker Titans use arc light to charge their fists with lightning to obliterate their foes with a deadly close range ability known as Fist of Havoc. In Destiny 2 they can also gather arc light to transform into a missile in a super known as Thundercrash to deal massive impact damage.

Bladedancer Hunters use arc light to manifest a pair of daggers known as Arc Blades.

Arcstrider Hunters replaced Bladedancers in Destiny 2 and use arc light to create a fighting-staff known as an Arc Staff. They can also throw this Arc Staff to create a damaging area of effect known as Gathering Storm.

Stormcaller Warlocks use arc light to destroy their enemies with the power of the storm known as Stormtrance. By concentrating the arc light into a smaller area, they can unleash a long range, more accurate beam known as Chaos Reach.
