The mechanics for this minigame are different from the game's normal combat.

• Firstly, the punching bag doesn't "get hit" like enemies do. Thus, cores like "get MP on crit" won't activate and targeting artifacts like Shadow Sword or Mosquito Beam don't work.
  
• Secondly, you aren't actually doing any damage to the punching bag. Every move gives you a specific amount of points, so some moves/Artifacts/weapons are better for this challenge than others.
  
• Thus, this minigame mostly rewards hit count more than damage output. So, high level gear and setups don't make a massive difference, as shown with my gear setup.

After doing some light experimentation, I found an easy way to hit the 3000 point requirement for the achievement.

The setup is as follows:

• Use Ciara with a Sniper (the weapon tier doesn't matter since you aren't doing damage).
  
• Use two Tracking Sphere spells/Artifacts. The tier doesn't matter, however lower tiers cost less MP and thus are better.
  
• Cores don't matter too much, however there are a few helpful ones, namely:
  
  • If you don't have access to Rechargeable Magazines, then cores with the Master of Magical Bullets effect will help. There are three levels of that skill on the following cores: Automatic Turret A Core (from Automatic Turret I), Administrator B Core, and Head Maid's Magic Core.
    
  • Skeleton Quartermaster Core; Reduces the cost of spells/Artifacts when under 50% max MP. This is useful if you have low max MP.
    
  • Berserk Demon Core; Increase MP regeneration. This is useful if you have low max MP.
• Here, I had around 400-450 MP. Equipment, meals, stat boosting fruit and cores can help raise max MP.

The main three moves I'm doing give the following points:

1. Light Bullet (Sniper down-forward technique) = 120
   
2. Tracking Sphere = 80
   
3. Kick Combo = 38

The main strategy is to do as many Light Bullets and Tracking Spheres as possible. Rechargeable Magazines give Ciara infinite ammo bar, allowing you to continuously use Light Bullet instead of falling back to melee combos, which is very helpful for this challenge, but not strictly necessary. They are obtainable after completing the Mechanic List 5 quest for the Ice Prison area. Tracking Spheres have a cooldown and should only be limited by your max MP, just spam them as often as possible. Dashing is useful for cancelling the ending lag of Light Bullet.

I have experienced an issue where all the hits of the tracking sphere shots didn't register when firing both at the same time. If this happens, then this strategy should still work, but you will have to alternate casting tracking spheres instead of casting both at once.

This minigame requires you to put out fires with water based artifacts.
Two artifacts can put out fires; Water Ball and Torrent.

The basic idea of the strategy is to just use the Torrent artifact on the left and right walls at the top. Torrent is expensive, but it can completely douse all three fire spots when cast at the top of the room, so it's better than using Water Ball. Because it is so expensive, you will want to farm six of them in order to equip it on both slots of all characters. There are no specific gear recommendations, as shown in the demonstration video. The Skeleton Quartermaster Core is useful to get a few more Torrent casts per character, and gear that raises max MP helps. MP Potions are available as well.

Torrent can be obtained from specific torches. The only place that I have currently verified is the torch in the lower save room of the last area, the Sky Temple, although they are obtainable before reaching this minigame.
