Before fighting the gatekeeper Clumsy Wall, it's recommended to equip the accessory "Shield Breaker Charm" and the Shadow Armament "Great Fierce Axe." Also, use a weapon with strong shield-breaking capabilities; a large sword can speed up shield breaking. One charged axe strike can break more than half of its shield.
Let's take a look at its skills together below.
Blue Light Attack 1: Slams the ground seven times in succession, with the seventh hit being a blue light attack.
Blue Light Attack 2: Slams down once in every direction around itself, with the final hit being a blue light attack.
Red Light Attack 1: After the final slam of the preceding Blue Light Attack, it causes an explosion around itself, then swings its shield to grab us.
Red Light Attack 2: Directly raises the shield to charge up a red light downward slam.
Red Light Attack 3: After turning its back to us, it performs a backflip to charge up a red light attack.
Red Light Attack 4: Spins the shield to attack us, with the final hit being a red light attack.
Red Light Attack 5: Thrusts forward with the shield twice, with the final hit being a red light slam.
Black Light Attack 1: Jumps up and charges a downward kick with black light.
Black Light Attack 2: An attack triggered only at low health. Uses the shield as a skateboard, with the dash being a black light attack.
Red Light Attack 6: Triggered at low health, similar to the previous move. During the black light skateboard dash, it suddenly switches to red light.
Red Light Attack 7: After rocks appear during the first ground slam, the second ground slam with rocks becomes a red light attack.
Blue Light Attack 3: Similar to the previous move, except the first ground slam is now a blue light attack.
Defeat him to obtain the Shadow Armament "Clumsy Wall Shield".
