Minecraft Dungeons:Mission Select

There are many different locations, known as missions or Boss Missions  if containing a boss mob, to find and explore within the world of Minecraft Dungeons. They are typically unlocked through completing predecessor missions, although in the cases of Secret Missions that are unlocked through obtaining secret scrolls.

Overview
Locations can be travelled to from the map once players have reached or returned to the Camp. They do not appear on the map until they are unlocked. Due to the nature of how the missions are unlocked, it is entirely possible to skip missions to complete the main story. There are a maximum of 31 (not including Camp) playable locations at any given time if all Secret Missions and Daily Trials are unlocked and all DLCs purchased. Each location contains over 500 mobs (except for Squid Coast, which has less than 100 mobs)

There are three main things that can be found in a location: Emeralds, Consumables, and equipment such as Weapons, Armor and Artifacts.
