Cuphead

This achievement can be completed on Simple difficulty no need to worry about the difficulty you are playing on if you want to make it easier on yourself.

This achievement isn't too crazy as long as you select the correct level! Bootlegger Boogie is one of the best choices due to it's final phase. In the final phase, you fight a snail with extremely low health who can be taken out with very little issue using Super Art 1.

So, let's talk about the recommended weapons I would personally bring.

First Weapon - Roundabout Shot
This is extremely useful for taking out the first boss AND dealing with any enemies surrounding you at the same time.

Second Weapon - Chaser Shot
This is to be used during Phase 2 / 3. Just because you are going to be too busy dodging the attacks to find time to line up a shot. Even though it's weaker, it's the best choice.

Super Art - Super Art 1
This is the move you should use against the snail, because it is a straight vertical attack that easy to line up with the enemy.

I'd recommend you check out the video for further information on the boss phases, as it is more easily shown than told. But as a basic breakdown:

Phase 1 - Spider
This enemy goes between rows using differing attacks with a ton of minions all around. The attacks I would watch out for are the centipede the enemy throws, the charge attacks he has (if he isn't on the phone or holding a button, he runs into you), and then the bombs he calls in. They are very easy to dodge, but just be aware that they blow up if you end up near them. Staying on the middle row firing the Roundabout leaves you in a good position to move out of the Boss' path.

Phase 2 - Bee
Stay on the top row shooting the Chaser Shot and rolling through the attacks coming from the record player. Ensuring you roll when the beam is red to avoid damage.

Phase 3 - Ant Eater
This enemy only attacks one side of the screen at a time and shoots a spit ball after they are finished with one side. Firing the chaser constantly will destroy the spitball and continuously damage the enemy when it can lock on to it. This phase just takes some time due to the low damage from the Chaser shot.

Phase 4 - Snail
Line yourself up below the snail and perform your Super Art attack to unlock the achievement!

If you drop any negative feedback, please PM me to inform me why. Constructive criticism will only make the information here better!

I did this on Isle 1 with the boss Root Pack on simple difficulty I used spread the whole fight and didn’t parry once, once you get the 5 cards shoot for a few seconds more then use your super and it should be a knockout!
