Vault Duel

Break the vault guardian with two forged blows and survive its visible sweep pattern. Tap a neighboring empty room to walk. Walking onto an equal weapon pickup doubles your carried blade and consumes the pickup; a different value blocks the room. Strike works only beside the guardian, deals your blade value, and halves the blade afterward. The guardian repeats three intents: sweep the middle row, sweep the middle column, then recover. Every walk, Strike or Wait resolves the displayed intent for 3 damage if you remain in that line. The guardian room and dark corners are impassable. Reach sixteen damage, strike, then find an eight pickup to reforge the blade for the finishing blow. Keyboard: Tab and Enter/Space operate buttons; R restarts.
