To earn Wall Mastery in Drop Duchy, win the battle against The Wall with no enemies left. The achievement listing states: “Win the battle (no enemies left) against The Wall.” You must clear every enemy, not merely defeat the boss.
What Wall Mastery requires
Both the Steam achievement listing and the Epic Games Store listing give the same condition: win against The Wall with zero enemies remaining. Epic lists a reward of 10 XP.
Do not confuse Wall Mastery with Off The Wall, a separate achievement whose listed condition is to defeat The Wall with any faction. The zero-enemies requirement belongs to Wall Mastery.
How to approach the Wall battle
The official achievement listings describe the win condition, but do not prescribe a faction, card, item, or fixed build. A Steam community strategy discussion offers encounter-specific advice; treat its mechanical details as player-reported guidance, not an official rule reference.

Plan your board placement
The discussion says the encounter begins when a tile extends into The Wall’s red silhouette. It also reports that unfilled spaces count as three additional units for the nearest enemy building. If that interaction applies in your current game version, leaving gaps near enemy buildings can make the opposing force substantially harder to manage. Arrange tiles with both the silhouette and open spaces in mind, and verify the exact behavior in-game rather than relying on the reported number as a guaranteed current rule.
Use terrain tools to make placements workable
Players in the discussion suggest using terrain manipulation, including Farm and Wood Clearer, to improve awkward Forest placement. This is a situational suggestion, not a proven build: use those tools when they help you arrange the board and avoid creating dangerous gaps, rather than treating either as mandatory.

Build toward clearing every enemy
Because the condition requires no enemies remaining, judge your setup by whether it can deal with the entire opposing group, not only The Wall. A commenter also reports that bosses can count for adjacent and line-based military-building effects, with The Wall’s contribution added at the top. That interaction is community-reported; check how your current setup resolves those effects before relying on it.

- Confirmed: The Wall must be defeated and no enemies can remain.
- Not specified by the achievement listings: a required faction, particular card, physical item, or fixed build.
- Community advice, not a guarantee: the reported red-silhouette trigger, the three-unit effect from unfilled spaces, and the suggested terrain and military-building interactions.
