Part 20

After using the airship to reach Armor Outpost, you can obtain a [_MUSIC SHEET_].

Proceed to either the Knuckler's Quarry or the Black Knight fight. This guide will cover (press the cover button to crouch behind walls or objects) Knuckler's Quarry first.

Enter the Knuckler's Quarry and speak with the NPC (non-player character — anyone the game controls, not you) to practice using the Dust Knuckles on dirt.

Cross the lava, using the Dust Knuckles on dirt to reach a [_CHEST_] and the next screen.

Dash through dirt to a platform and continue right.

Drop to the next set of dirt blocks, avoiding lava drips.

Head up quickly and defeat the chemist enemies to protect the dirt.

Use the dirt to reach a pink gem in the upper right, then collect gems below.

Head down and punch through a bubble in the dirt, bouncing off it to reach more dirt and a slime enemy.

Continue down to a [_CHEST_].

Land on a magic pot to the right of the chest, then punch through subsequent dirt blocks to reach bubbles.

Use the bubbles to bounce to safety and hit another [_CHEST_] for a [_MUSIC SHEET_].

Collect all remaining gems on your way out of the area.

Next, prepare for the Black Knight boss fight.

The Black Knight has more health and new moves, including the dangerous Energy Dig.

Be ready to hit projectiles back at him, as he can return them.

His Shovel Swipe is a basic attack.

His Energy Shot can be jumped over or hit back.

His Downward Strikes can be initiated from across the screen; jump and hit him in the air.

The Energy Dig attack involves him digging into the earth and throwing four purple energy balls; use your Phase Locket (an item that grants temporary invincibility) or retreat to avoid them. Do not attempt to hit these back.

After defeating the Black Knight, you will receive gold.

To enter the Hall of Champions, you need 5,000 gold.

PS4 players should note that a hidden element in the Hall of Champions unlocks the hidden Kratos boss fight.
