How to Beat Demon Wall

Conquer Peglin's Demon Wall boss by focusing on burst damage. Learn the strategy for its four self-healing cubes and how bomb builds aid this fight.

Location: The Castle (Map 3)

The Demon Wall is a unique boss composed of four separate, self-healing cubes. It demands high burst damage.

• Phases: One main phase, but effectively four targets.
• Mechanics: Four cubes, each with 3500 HP, that heal themselves.
• Strategy: This boss is a prime target for bomb-focused builds, especially with the Scientist. Relics that convert black bombs to red, increase bomb damage, and make bombs activate in one hit are crucial. Aiming between the four moving peg boxes can trap your orb and clear out multiple bombs from each cube. Be aware that red bombs cause self-damage, so monitor your HP. It's possible to defeat all four with a single powerful attack.
• Weaknesses: High area-of-effect damage, bomb chain reactions.
• Rewards/Achievements: 'All In All' for defeating him. 'Not a Dull Wall at All' for converting or destroying 3 dull pegs during the fight. 'Surprised the Ruins' for defeating all 4 Qaballistic Ruins with the same attack (some sources suggest this is for the Demon Wall, others for a different boss, verify in-game).
