Divine tears are an item part of the Battle of Lumbridge, and cannot be banked. Divine tears are collected on and off the battlefield. You can get them by gathering, or by fighting. Divine tears can be obtained from Glowing Crystal's (Woodcutting), Glowing Rocks (Mining) and Glowing Pools (Fishing)
Divine tears can be turned in for Renown, which can then be used to buy armor, experience lamps, titles, or single-use items from the Zamorakian quartermaster or Saradominist quartermaster.
Occasionally some of the divine tears gathering spots get unstable and the player will take damage if trying to gather from these resources. When they become unstable they will turn brighter green or more red/orange.
