Lasli, who you may remember from Breath of the Wild, needs your help in treating her sick grandmother. As part of the Gloom-Borne Illness side quest, you must help her find the necessary ingredients to cook a special porridge in Zelda: Tears of the Kingdom.
Helping Lasli out here will get you an Energizing Veggie Porridge as a reward. Here is how you can find the ingredients for the porridge Lasli intended to make to cure her grandmother.
How to start Gloom-Borne Illness Quest in Zelda: TotK
The Gloom-Borne Illness side quest can be obtained in two ways in Zelda: Tears of the Kingdom. The first method is to talk to Claree inside the Enchanted store (armor shop) in Kakariko Village. She will ask 15,000 Rupees each for Stealth and Radiant armor sets.
Upon inquiry she will tell you that her grandmother is sick, and she is trying to raise funds for her treatment.
The next way is to talk to Lasli, Claree’s sister. You can find Lasli near a cooking pot (1908, -0999, 0127) in the eastern part of the village. It is under a shed, and you can find Lasli there any time of the day.
Once you talk to her, she will tell you that she is trying to create a unique porridge to cure her grandmother. Lasli will give you the recipe to create the Sunny Veggie Porridge and this will officially start the Gloom-Borne Illness quest in Zelda: Tears of the Kingdom.
How to complete Gloom-Borne Illness Quest in Zelda: TotK
The ingredients required to cook the Sunny Veggie Porridge include Sundelions, Hylian Rice, and Fresh Milk.
1. To purchase Fresh Milk, fast travel to Hateno Village or Lookout Landing. The general goods shop (3366, -2174, 0120) there has Fresh Milk for 12 Rupees per pack. You can buy three of them if you want.
2. The same shop has Hylian Rice available for 12 Rupees. The upper limit to buy Hylian Rice is 5. You can also purchase Hylian Rice from the general store in Lookout Landing.
3. To procure Sundelions, you must travel to any Sky Island. They are available abundantly on each Sky Archipelago. There is no place to pinpoint, but your best bet is to start from the Great Sky Island. Fast Travel to any shrine there, and you will obtain a Sundelion in no time.
4. Once you have all the ingredients, return to Lasli’s location and cook the Sunny Veggie Porridge (hold the ingredients and throw them in the cooking pot).
5. Hand over the porridge to Lasli, and she will use it to heal her sick grandmother.
Rewards
Multiple rewards are associated with the Gloom-Borne Illness quest in Zelda: Tears of the Kingdom. Lasli will reward you with an Energizing Veggie Porridge.
Claree will be there and ask you to visit her armor shop once more. Now, you can buy Stealth and Radiant Armor sets for a fraction of their original cost.
When you visit Kakariko Village in the future, you will notice Lasli and her grandmother have managed to grow Sundelions. You can now collect Sundelion from their property instead of visiting the Sky Islands.
