Bullseye

Bullseye is a challenge advancement in the Adventure tab of Minecraft's advancement system, carrying the in-game description "Hit the bullseye of a Target block from at least 30 meters away." It branches directly off Take Aim, so that earlier advancement is its prerequisite and must be earned first. The Adventure tab covers advancements focused on exploration, combat, trading, and interacting with the world and its inhabitants. Bullseye was added in Minecraft 1.16, from the Nether Update, and is still in the 26.2 advancement set.

It is rated Medium difficulty on this site: requires some preparation or specific resources. Part of normal gameplay progression. Because it is flagged as a challenge advancement, completing Bullseye makes a special toast and a sound play, and its frame in the advancement screen is the magenta challenge style rather than a normal square. Challenges are the hardest tier and usually represent a milestone rather than routine progress. Nothing else in the tree depends on it, so it is a leaf at the tip of its branch.

In tree terms, Bullseye sits third along its line: the full path from the Adventure root reads Adventure -> Monster Hunter -> Take Aim -> Bullseye. That means 3 advancements must be completed before this one becomes available, and Bullseye is one of 47 total advancements in the Adventure tab. It shares its parent, Take Aim, with one sibling, Sniper Duel, which unlocks from the same point.

Completing Bullseye grants 50 experience points, reflecting its status as a challenge, and challenge advancements pay out far more XP than ordinary tasks. The XP drops at your position the moment the advancement fires.

It is a leaf advancement, so nothing further unlocks from it; it stands as a completed tip of its branch.
