All players can Rain BKD on other players randomly, or they can choose to rain on specific players. Staff members can make it Rain on any random player at any time. Asking for Rain on the chat is not allowed.
How can I claim my Rain credits?
After you get some Rain, you will get a notification (a green dot) in the My Bonuses section. You’ll need to go to the sidebar and click on My Bonuses to claim the Rain. You’ll have the possibility to claim your rain BKD in any currency you choose.
