First and foremost, Khimera's ranking system is based entirely on the CASH MONEY value. You can take as long as you like and even use the berserk mode outfit to quickly dispatch enemies. A Rank is awarded for finding at least X amount of treasure in a stage. We'll call that amount the BORDER VALUE.

As of 1.5, border values for each stage are as follows:

• Ragazza Plains - €3,170
  
• Sky Fortress - €3,350
  
• Mt Afrokupa - €3,600
  
• Pumpkin Valley - €3,800
  
• Oil Platform - €3,900
  
• EX: Tower of Power - €630
  
• EX: Icey Path - €680
  
• EX: Windy Way - €340
  
• EX: Brine Cave - €1,300
  
• The Black Widow - €4,100
  
• Mechanical Mayhem - €9,250
  
• The Spider's Web - €3,710

Simply have cash money at or above these values for the given stage and that A rank is yours! Otherwise, this is the breakdown for the other ranks:

A Rank - >=100%
B Rank - >=80%
C Rank - >=60%
D Rank - >=0%

Bosses drop €1,560: Every boss (except for Khibeara and the Captain) will drop exactly €1,560, so really most A-Rank goals are actually about half.

There is room for error: You do not need to pick up every penny to get an A Rank. Every stage has surplus money hidden so you have a safety net in case of a death or dropped treasure. That safety net varies by stage but in general it is not strict at all if you find all of the big hidden stuff. In general though, dying less means collecting less, so be safe out there.

Get the Lucky Chax Doll: This item will give you the ability to pull treasure to you, making grabbing dropped treasure much easier (it even lets you pick treasure up through walls). You can get the Lucky Chax Doll as early as Ragazza Town becomes available to you. Simply complete the trading quest to acquire it.

Defeat Enemies: Every enemy has a treasure value (they'll drop the same amount every time). Defeating them for the first time will yield this treasure. Note that if you leave an area and they respawn, they will not drop treasure again after they've dropped it once.

Find the Fairies and notebooks: Every fairy you find is an easy €100. Make sure you grab them all on your A-Rank run. Most secret rooms containing notebooks or fairies will also yield extra treasure. Brush up on the locations of all the hidden fairies and notebooks using this handy guide by dorko4u!

Look out for false walls: They're all over the place and usually have €50 or €100. You can use the cyclops eye to quickly find false walls. Most are marked but if you're not sure, just do down+S to scope them out.

Find Gourmet Gal: Her rooms never have treasure, but having the extra max health really helps you when you need to not die. Keep an eye out for her or use this guide to find her!

Goal: €3,170

One of the less lenient stages due to how short it is. You'll need to get all the fairies in this one, make sure you stop by the notebook room (with the waterfall) to grab those gems as well. You can probably die once and be ok.

Goal: €3,350

Fairly lenient. You can die a couple times and still squeeze by with an A. The second fairy's room is especially profitable, so don't miss that! There is a lot of treasure out in the open in this stage so it shouldn't be too hard to A rank.

Goal: €3,600

Again fairly lenient and you CAN die as long as you're collecting almost everything. Still advise against it. Make sure you grab the extra treasure in the notebook rooms, they're easy to miss.

Goal: €3,800

There's a lot of treasure in these stages. Notebook rooms are important as they have a lot of treasure. Both the pumpkins and the zombies are easy to miss treasure on. If you punch the zombie's head after it pops off, you can get some extra cash this way. Dash into pumpkin heads while they're in midair to claim some extra dosh as well. Its not mandatory to get them all, but it really helps.

The first Kiran (the infinitely spawning witch) you defeat will net you an easy €50!

Goal: €3,900

Look out for the shells embedded in underwater walls. They indicate a false wall. There's at least two sections where you can get €100 from them. A lot of the ghillisuit fluffs are optional kills that can really add up. Make sure you grab the treasure room left of the first screen underwater.

Goal: €630

An easy A-Rank as long as you defeat the majority of enemies on the way up. Berserk mode makes this a breeze since you'd die in one hit anyway from the rising spikes.

Goal: €680

There are a few treasures you can miss if you don't keep up with the platforms. Having the Lucky Chax Doll alleviates this. This should be an easy A if you don't die to Khibeara.

Goal: €340

Not very lenient, you'll need to defeat almost everyone to get this one. The room full of propeller fluffs where you find the fairy is especially important.

Goal: €1,300

The longest EX stage so its less precise than the others. Its easier to do when you don't need to rescue the fairy as the gem will just come to you if you have the Lucky Chax Doll. Make sure you get the treasure room on the way up the small vertical segment after the checkpoint!

Goal: €4,100

A very lenient stage! You can die maybe four or five times if you gather most the treasure. There are a lot of rooms dedicated to treasure (one at the top of the disappearing ghost segment and one after the third checkpoint to the left). The samurai are a pain but they give good dosh and can be OHKO'd with the saucy shot (even while countering).

Goal: €9,250

Unlike the Black Widow, this stage is a lot more precise. You need to make sure you're collecting all you can before the boss rush. Once it comes time to face the bosses, make sure you're grabbing their treasure before you're brought back to the HUB room. Probably the toughest one to do. Berserk mode makes this a LOT faster.

Goal: €3,710

This one will automatically be an A Rank if you grab the treasure in the notebook room on the way down. Just hug the left wall and get to punching!
