Recharging the Sundial
Collect Light to recharge the Sundial by defeating opposing Guardians in Crucible or Gambit modes, getting kills with your Super, and collecting Orbs of Light.
"The Sundial is my greatest creation and my greatest regret. What I had to do to forge it I can never take back. As a result, it has components that consume Light. And if you're serious about operating it again, you'll need to feed it. Nothing is free. Ever." —Osiris
