The Era8.5 update gave Jake and Lime a vacation for the Summer event in Sol's RNG. In addition to the new Auras, Gear, and items, you can talk to them on the beach to get some quests and limited time Auras and receive some awesome rewards.
COMPLETE THE HIDDEN QUEST! (SECRET REWARD) | Sol's RNG
Jake and Lime will give you a total of three quests and as usual you will have to throw a lot of them to complete them. You will have to collect a total of eight Auras, buy a Rainbow Syrup from the Traveling Merchant Mari and collect Lucky Potions from the ground or brew them with Stella's Cauldron.
Collecting everything can take a while, especially the last quest and the Watermelon Aura, which was introduced to the game with the Era8.5 update. Here is the rarity of all the Auras you need to complete all the Lime and Jake quests in Sol's RNG:
The biggest difficulty is getting three Solar and two Watermelon. If you have found an Aquamarine, Solars and the other Auras earlier but don’t have them in your inventory, you can go into the settings by clicking on the gear icon on the left side of the screen and open the Aura Filter option. Then scroll down and click on the empty square next to the Aura line to enable “Auto Equip Mode”. This will ensure that you don’t lose these Auras when you roll them into Sol’s RNG, especially if you have auto skip enabled.
