Dusk Diver 2 is split into a number of Chapters, and the game’s fourth Chapter is not only lengthy but also quite the jump in difficulty. Enemies are stronger, combats are more numerous, and frankly, EXP is in hot demand. The real kicker? There are two bosses in this Chapter, and both can be quite the pain to take out.

The first boss you encounter is Large Chaos Beast Type Lambda. Awful naming conventions aside, this Chaos Beast is quite the challenge. It is larger than any boss you have fought so far, deals more damage, and is surprisingly good at catching you mid-dodge thanks to his long reach. Let’s break it down.

Chaos Beast Lambda’s Attacks

Dusk Diver 2 Boss intro for Large Chaos Beast Type Lambda

Chaos Beast Lambda has a fair few attacks, but they all share the same general theme - hit hard from a deceptive range. This thing is more than capable of clipping you when you least expect it - so much so that you might lose some party members in this scrap if you aren’t careful.

Attack

Explanation

Counter

Body Slam

This is Lambda's most basic attack. He simply jumps into the air and slams back down - belly first

This attack is well telegraphed and comes out rather slow. Avoiding it is incredibly easy with a dash.

Overhead Slam x2 + Red Swing

This attack can catch you out. It starts with two powerful overhead attacks. These deal great damage, and sometimes, the combo ends here. Other times, however, Lambda will combo this into a power red swing attack. This deals more damage, comes out deceptively fast, and has a lot of reach.

The best way to deal with this combo is to simply dash away. The overhead slams have reach, but you should be able to chain two dashes together and get to safety. If Lambda flashes red, then consider falling back some more, or dashing into range and countering him for bonus damage.

Red Whirlwind Spin

Lambda flashes red and then spins around and moves towards the party like a fleshy hurricane. Can hit multiple times, and can wrack up a lot of damage if you get caught in it.

You have two options - run away, or counter. Running away is the safer option. Lambda will track you, but the attack is rather slow, so getting away is not too difficult. If you want to counter Lambda, then you need to be close to him when the attack starts and counter just as he starts the attack. If you mess up, this can lead to a lot of damage being thrown your way.

Whirlwind + Bodyslam

Lambda does a whirlwind spin (he does not flash red for this one) and then ends in a powerful bodyslam attack.

Since you can’t counter this attack, your only option is to dash away and stay out of range. Once the bodyslam lands, dash back in for some free damage.

Double Swipe

Lambda swipes its arms in a wide arc and deals decent damage.

This attack is easy to dash away from. Try and land a Just Dodge on the second swing to get some free damage in.

Which Party Members To Use

Normally Yumo is the go-to for bosses as she can handle just about any situation. However, we found that Yumo’s counter was surprisingly unreliable in this fight - often failing to trigger. Since Large Chaos Beast Lambda has two counterable attacks, we recommend running with Leo as his Block is an excellent defensive tool and much more reliable at countering.

You could also run with Viada. Lambda has a lot of range due to its long arms, but Viada has the advantage of guns. She can stay back and fire away from relative safety whilst her companions distract Lambda on the frontlines.

Battle Strategy

Large Chaos Beast Lambda can be tricky if he backs you into a corner. Its attacks are excellent at catching you out in a confined area, so make sure you know your escape routes. You want to stay most central and move in circles, as opposed to backing away and towards a wall or corner.

Lambda is also accompanied by four Bipedal Chaos Beast Alphas. These are your standard enemy, and you’ve killed plenty of them before. These are more of a nuisance than a threat. Regardless, you need to take them out first otherwise they will wreak havoc on your party. Just be aware of Lambda and where it is. Lambda will take advantage if you are not paying attention to it.

Healing potions are essential in this fight. Things can go very wrong very quickly, and having some healing on hand can help cover up any mistakes you might make - especially early on when you are dealing with his minions. BP potions are also excellent, as they let you stay in Burst for more of the fight. This is especially handy early on since Bursting can very quickly deal with Lambda’s minions.

Lambda should go down after you drain his armour twice.
