The ‘Fortunate Encounters’ event is live in Tiny Tina’s Wonderlands. During this event, you will get more loot and Moon Orbs from the Random Encounters you have on the Overworld map. This event runs from June 30 to July 7 at 9:00 AM PT.
Random Encounters can happen in tall grass areas on the Overworld. An enemy will appear on the Overworld and it will chase you down. When the enemy collides with your character, you will be teleported into a small arena. There you will get to fight against a wave of enemies. At the end of the encounter, a giant crystal die will wait for you. Loot will pop out of the die when you smash it.
You also get these crystal die after completing a camp encounter. The number of Moon Orbs seems to be in the same range as the Random Encounters on the Overworld.MentalMars
