In Age of Calamity, Quests serve as the way to increase the effectiveness of a Warrior, replacing the Bazaar's Badge Market found in the original Hyrule Warriors games. By using Materials, Link and the other Warriors will gain attributes such has extensions of their Light Combo, a new Strong Combo, Hearts, and more Special Attack bars. In addition, some Quests grant pieces of Attire for Link to wear.
To unlock more Quests, Warriors must progress through the Story, complete certain Challenges, or finish other Quests. There are 376 Quests in total in the base game.
Quests are split by the following within the Quest tab:
- Character-specific Quests, which benefit only one Warrior. These Quests are marked with the heads of the characters as depicted by the narration cutscenes, and are all found under their Warrior's name under the Quest search tab (e.g., all the Side Quests that benefit solely Link will be found under the tab "Link", and so on & so forth).
- Improve All Allies Quests, which as the name implies, benefits all Warriors. These Quests are marked with a heart icon.
- Sheikah Runes Quests, which lowers the cooldown of used Sheikah Rune abilities. They are individually marked with their specified rune (e.g. the Quest "Explosive Endeavours" is marked with the Remote Bomb logo).
- Divine Beasts Quests, which improve the vitality and functions of the Divine Beasts. They are individually marked with the specified Divine Beast.
- Unlock Services Quests, which open up Shops and Stables to shop for certain Materials if the need arises, as well as other vital specialized services. Shops have a Jar marker, and Stables have a horse head marker. The specialized services are:
- the Hylian Blacksmith Guild, marked with a hammer, helps Warriors by tinkering with weapons to make them stronger.
- the Military Training Camp, marked with a helmet, help lagging behind Warriors catch up with the currently highest leveled Warrior.
- and the Kochi Dye Shop, marked with a vial, changes the color of Link's clothes, with the Rupees depending on the dye.
- Improve Services Quests, which gives Link and co. discounts, as well as more services with the Blacksmith Guild, and additional dye options for the Dye Shop. These are marked with a building & an up arrow.

Aside for "The Treasure Detector" which is marked with a treasure chest icon, all Battle Support Quests have their marker be Hestu's Maracas.
- Sheikah Sensor Quests, which help Link and co. use the Sensor to help find specific Materials in either combat missions or Shops/Stables if they are too few for a specific Quest. Like the Runes Quests, these quests are marked with the Sensor icon.
- And finally, Contribution Level Quests, which are region-specific quests that keep track of the completion rate of the Quests of that region of Hyrule, and are thus completed when all Quests in a specific region are completed. They are marked with a star icon.
With the Pulse of the Ancients Downloadable Content pack, 54 additional Quests have been added to Age of Calamity. 35 of these Quests can be found within the new facility, EX Royal Ancient Lab, marked on the map with a Ancient Screw with an "EX" next to it. These Quests are largely meant to help the lab grow and prosper. The Lab's Quests are arranged in a grid and operates similarly to how the Badge system from the original Hyrule Warriors worked; completing one Quest can unlock the others that connect to it as long as the player has the Materials or the Rupees for it. The Quest icons also retain the previously established rules with what they entail.
Quests from the EX Royal Ancient Lab grant access to new rewards added in Pulse of the Ancients, as well as the newly added Materials needed to complete them. Additionally completing them grants access to the Flail for Link, the Battle-Tested Guardian, and the Master Cycle Zero for Zelda.
