· The Grand Knight is an outdated boss in an era with plenty of cover, limiting bounce, explosion, and area attacks.
· The Grand Wizard has weaknesses like poor melee counter-attack and no reflective bullets, but shows exploitable behavior during laser or square patterns by doing nothing in the opposite direction. However, be cautious of knockback if resistance is lost.

· The Giant Slime is a very challenging boss that fires a massive number of bullets in all directions and even self-destructs when its health drops below a certain point.

· Once a very difficult boss for this stage, it remains a threat with its attack speed nerf and various patterns like split bullets and trajectory-changing thrusts. It has higher HP than the Grand Knight.

· The Skeleton King has solid attack patterns, but its difficulty can be reduced by exploiting its tendency to stay put during summon or homing bullet patterns.
· The Wraith has well-placed cover and many openings, but be wary of its pattern of blindly running away during lasers or bombardments.

· King Yama can be damaged with only melee attacks during its pull-in pattern, but otherwise, its attacks combined with the Wraith's and the final boss's become challenging. It's generally considered moderate difficulty.
· The Headless Knight has low HP but its body and head attacks are dangerous. Especially the head's charge and area-of-effect combo is a maddening synergy.

· Cheese Down boasts high HP and fast movement speed. When its HP drops below half, its patterns become more erratic and its attack angles diversify, making it no easy boss.
· Quick is only large in size; its patterns are sloppy, and it has the shocking characteristic that its central slam attack can be avoided by staying in the center.

· The Infinite Treant has it all: dense bullet patterns, annoying summons, poison zones, and self-healing, all while having high HP. Its difficulty decreases if you know the strategy or have invincibility skills, but otherwise, it's very tough. There's also no cover in its boss room.

· The Ice Cave Drake uses various patterns like wide-range non-contact attacks, self-healing, and burrowing. The boss fight takes place on an icy surface, making movement awkward and challenging. While the difficulty itself isn't high, the environmental factors can make it tough.

· Mu Dong So Ja is a unique boss with shield and bounce abilities. It might be easy for players using Knight's 3rd skill, but the bubble shockwave pattern on the cliff edge is extremely dangerous and can turn you into a corpse in an instant.
