Wiz is the boss found in Peppermint Palace. Due to Wiz's erratic movement patterns, lots of practice is needed to efficiently react to them.

Parasol

Parasol is the most common ability used against Wiz. Parasol has 2 ways of dealing damage: with its passive hitbox, and with its active attack. The former deals more damage, but is riskier to use in some cases. Go to the right wall and slide left to position your Parasol hitbox at the start of the fight. Then, jump into the center platform after landing 4 or 5 hits to dodge Wiz. Wiz's behavior will vary from here. If he goes up, float up to meet him with your Parasol hitbox and keep floating beside him. Otherwise, attack using Parasol.

If Wiz has less than 25 health, you can attempt to finish him off by setting up a double star. Drop your ability while Wiz taps his hat, and then inhale both the ability and whatever Wiz spawns. This strategy can be risky since it isn't guaranteed to work depending on the enemy spawned, and gauging the boss's actual health is difficult. However, the upside of it is that if you deal maximum damage with your passive hitbox (14 hits) in the first cycle, a double star can finish the boss as soon as the second cycle starts. If the double star doesn't finish Wiz off, you'll need to use another star bullet from a different enemy spawn.

Hammer

Hammer is an advanced fight that requires acquiring it from a mix earlier in the segment. It takes 3 upswings and 8 additional damage to defeat Wiz with Hammer. The 8 damage can be dealt with either 2 attacks, or 1 attack and 2 wind-up hits from the upswings. Depending on how Wiz moves, it's possible to defeat him in one cycle.

The most common setup starts the same way as Parasol, by sliding from the right wall. Upswing twice the moment Wiz's health approaches half full. If Wiz goes up, jump and spin attack. Otherwise, there's a chance Wiz will damage you and make you lose your ability. Simply retrieve it, then chase Wiz and do another upswing. Finish Wiz off with either a spin attack or a turnaround swing.

Throw

Throw is an easier alternative to Hammer, both the mix and the fight itself. While slower, it almost always finishes the boss at the start of the second cycle.

Stand on the right side of the center platform and wait for Wiz to start attacking. Make sure to inhale from a distance, and react to multiple spawns by throwing away any previous ones in time. Hold down and away from Wiz, and turnaround if Wiz passes you. One held enemy should be enough to defeat Wiz. If you inhaled an enemy too early and failed to clear Wiz's health, eject your ability and shoot it at the boss.

The only pattern that can be problematic is when Wiz stops halfway across the room. If that happens, position yourself between Wiz and the wall. If your positioning is good enough, you should be able to land 2 hits while Wiz is at the center, and then wipe his health after he crosses over. This can only occur if you inhale an enemy fairly late, and if Wiz doesn't go up.
