Over-Overkill

Over-Overkill is a challenge advancement in the Adventure tab of Minecraft's advancement system, carrying the in-game description "Deal 50 hearts of damage in a single hit using the Mace." It branches directly off Minecraft: Trial(s) Edition, 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. Over-Overkill was added in Minecraft 1.21, part of the Tricky Trials update, and is still in the 26.2 advancement set.

It is rated Expert difficulty on this site: extremely difficult challenges that require extensive game knowledge and dedication. Because it is flagged as a challenge advancement, completing Over-Overkill 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, Over-Overkill sits second along its line: the full path from the Adventure root reads Adventure -> Minecraft: Trial(s) Edition -> Over-Overkill. That means 2 advancements must be completed before this one becomes available, and Over-Overkill is one of 47 total advancements in the Adventure tab. It shares its parent with 4 sibling advancements (Who Needs Rockets?, Blowback, Under Lock and Key, and Lighten Up), all of which open from the same point in the tree.

Completing Over-Overkill 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.
