Boost Speed with Accessories

Speed-Boosting Accessories
Feather	Zoom Shoes
Attack Scarf	-

First-turn decisions are crucial in fighting Engine 023 Booster, so it is best to have equipment that you will boost your speed.

This is helpful for members like Bowser, whose Terrorize will protect the whole team early from Booster and his Strong Snifters before they use their strong attacks.

Having the Attack Scarf on Mario will also ensure he will be able to disrupt Booster's work immediately when he faces away. He will able to take the first normal attack, or you can go directly to using Ultra Jump to deal with the Strong Snifters also.

Best Accessories

Have a 100% Action Gauge in Advance

It is best that you use a Triple Move attack as early as you can in the fight since being the first to make a move is important in keeping Booster and minions from retaliating with strong attacks.

Fill up your Action Gauge by defeating enemies prior to the boss fight within the Booster Tower!

How to Fill the Action Gauge Fast

Combo Bowser's Terrorize with All-Out Attacks

Use Bowser's Terrorize Use a Triple Move Use Special Moves Use Normal Attacks After Defeating Minions

1. Use Bowser's Terrorize

Special Move	Effect
Terrorize (Bowser)	・Inflicts Fear status effect. ・Rotate the left stick to increase the damage dealt by the Special Move.

Use Bowser's Terrorize to inflict Fear on the Engine 023 Booster and his Strong Snifsters. Make sure to time its Action Command for more damage!

List of Status Conditions and How to Heal

2. Use a Triple Move

When they have all been afflicted with Fear, have your team use a Triple Move (Clown Car Barrage when Mario, Bowser, and Mallow are in the active party) to do some big damage!

List of Triple Move Attacks

3. Use Special Moves

Special Move	Effect
Mechakoopa Stomp (Bowser)	・Deals damage to all enemies. ・Repeatedly press A to increase the damage dealt by the special move.
Snowy (Malow)	・Deals ice damage to all enemies. ・Rotate the left stick to increase the damage dealt by the special Move.

If Booster's minions are still alive, use multi-target attacks like Mallow's Snowy to exploit Engine 023 Booster's weakness to Ice, and Booster's Mechakoopa Stomp.

Best Special Moves for Each Character

4. Use Normal Attacks After Defeating Minions

Once the Strong Snifters have been taken out, you can proceed to deal normal attacks to Engine 023 Booster.

The 4-step guide above will at least make it easier for you to deal with Booster before him and his minions can do anything destructive, such as defeating your entire party in one turn with Loco Express 023.

It is recommended to try this strategy since it will minimize any accidents along battle and will make sure that Booster's work progress towards his super attack is not accelerated any further by his minions using Moral Support.

Watch Out for Loco Express 023

Booster's Loco Express 023 is a devastating attack based on the original Loco Express. This time it is stronger, targets the whole party, and is capable of defeating an entire party in one turn.

Deals Up to 9999 Damage

The Loco Express 023 can deal up to 9999 damage. To deal with this move, it is best to come prepared with revival specials and items such as Pick Me Ups for your party members on Standby.

This move is dangerous since the Strong Snifters can use Moral Support to reduce the charge time of Boost's Loco Express 023. If not taken care of quickly, your Standby party in a few turns.

Break Booster's Concentration

If you can immediately take out Booster's minions early, focus on breaking his concentration, since he will use Loco Express 023 if he completes his work. Attack him repeatedly to break his concentration, then shift your focus to the Snifters until his next attempt to work on Loco Express.

You can quickly break Booster's concentration by timing Mario's use of Ultra Jump (appropriate since he is also weak to Jump attacks) on him

Always shift your focus immediately on breaking Booster's concentration when he starts working on Loco Express, since his Snifters will try to accelerate the process with Moral Support.

Mute Does Not Prevent Moral Support

Take note that while Booster and the Snifters can be silenced from using specials by Peach's Mute, this not prevent Moral Support from being used by his Snifters to accelerate his Loco Express 023!
