Railgun with a two-stage primary attack and a special chain shot secondary attack.
LMB to fire lightning, an instant shot does 200 damage, and some additional damage as soft damage
Hold LMB to build up thunder after lightning (you'll see orange particles when it's ready) -- when you let go, it will fire thunder at the same location and do significant damage to players in its path. The particles turn red when a player is inside
- Hitting enemies with these attacks will power up the weapon's progress bar for the secondary chain shot. This is called the "Storm Shot".
- Once fully powered up, you can hold RMB to charge and fire the secondary chain shot (if you're familiar with Destiny's fusion rifles, it's like that)
- The chain shot will automatically jump to multiple enemies and do damage to each
- For each chain jump, it will spawn a secondary storm sphere that will damage everyone inside over time and explode after a small duration to do bonus damage.
- If you are affected by your own storm sphere's placement, you will receive soft damage.
- Hitscan weapon -- applies damage instantly at any range
