In the beginning of Final Fantasy 16, you may be okay with the healing power of your potions and the duration of your tonics, but as you progress through the story, they will not be as effective. Your health total will increase while your potions will heal for the same amount. To fix that, all you need to do is complete the side quests “The Root of the Problem” and “Please Sir, Can I Have Some Morbol.” However, it will take a bit to reach these quest, so hold on tight!

In Final Fantasy 16, you can upgrade the potency of your consumables through the side quests “The Root of the Problem” and “Please Sir, Can I Have Some Morbol.”

To unlock the “The Root of the Problem” side quest, you must first reach the “After the Storm” main scenario quest.

  1. Speak with Nigel to start the “The Root of the Problem” side quest. He will request you to search northern Rosaria for morganbeards.
  2. Travel to the “Martha’s Restobelisk in Rosaria, and head to the quest marker to the left of Sorrowise.

3. Either quickly grab the three morganbeards and run or defeat all of the goblins in the area to safely collect the morganbeards.

4. Return the morganbeards to Nigel at the Hideaway to complete the “The Root of the Problem” side quest.

Once you’ve successfully completed the quest, Nigel will give you morganbeard extract, which increases the potency of your consumables. With the phial of morganbeard extract, your potions and high portions restore more HP, while strength tonics, stoneskin tonics, and lionheart tonics last for a longer duration.

To unlock “Please Sir, Can I Have Some Morbol,” you must first complete the “The Root of the Problem” side quest and the “Like Father, Like Daughter” sub quest, which is part of the “A Song of Hope” main scenario quest.

1. Speak with Nigel in the Hideaway to start the “Please Sir, Can I Have Some Morbol” side quest.

2. Interact with Nektar at the Hunt Board to find that the Morbol resides in the Whispering Waters in Rosaria.

3. Teleport to the Three Reeds obelisk in Rosaria, and travel north toward the Whispering Waters.

4. Defeat Carrot, who will have similar attacks as other Morbols you’ve faced so far. Try to stay behind them avoid the acid puddles!

5. Return to Nigel and give him the morbol tendril to complete the quest.

Nigel will give you an invigorated morganbeard extract once you’ve completed the quest. With the invigorated morganbeard extract, your potions and high potions will heal even more HP, and your strength, stoneskin, and lionheart tonics will last even longer.

Now that you’ve upgraded the potency of your consumables, you should increase your inventory space too!
