Early Game

 
Step 1: Start The Run 
Okay, first off you need to start your run as Tainted Cain. 
 
Step 2: Conjoined 
Okay, this is the hardest part. You are going to need 3 familiars to get the Conjoined Transformation. 
 
The easiest and strongest familiar to craft is the Freezer Baby, costing only: 
1 red heart, 5 pennies, 2 bombs 
 
Step 3: Tractor Beam 
Once you are Conjoined, craft yourself a Tractor Beam: 
6 pennies, 2 keys 
 
Step 4: BFFs! (OPTIONAL) 
This is entirely optional but highly recommended, craft BFFs!: 
1 soul heart, 2 pennies, 5 bombs OR 2 red hearts, 1 penny, 1 nickel, 2 keys, 2 bombs 
 
Step 5: Birthright (OPTIONAL) 
Another optional but highly recommended item is Birthright, as it increases the amount of drops from item pedestals, i.e. more material to craft with! 
2 red hearts, 2 soul hearts, 3 pennies, 1 bomb OR 3 pennies, 4 bombs, 1 pill 
 
________________________________________________________________ 
 
That’s your DPS set up for now! You can steamroll early-game bosses efficiently with the familiars and triple shot you just gained, alongside your supportive frozen friends! 
 
 

Mid-Game

 
As you go further into mid-game (i.e. Depths), you’re going to want to build your army further, crafting as many cheap familiars as possible (or more expensive one’s, depending on your luck). 
 
This is where the guide is flexible, you can either build up the army or focus on building up your tear rate, damage or range! 
 
_______________________________________________________________ 
 
Cheap Familiars 
These familiars are the cheapest, easiest to obtain! 
 
Little Steven – 1 red heart, 1 soul heart, 1 penny, 1 key, 4 bombs 
 
Brother Bobby – 1 soul heart, 4 pennies, 1 key, 2 bombs 
 
Robo-Baby – 4 red hearts, 2 pennies, 2 keys 
 
Rainbow Baby – 7 pennies, 1 nickel 
 
______________________________________________________________ 
 
Useful Familiars 
These familiars are going to help carry your run, however they are not the cheapest so if you have crafted Birthright, you may be lucky enough to get these! 
 
Incubus– 1 red heart, 4 soul hearts, 1 black heart, 1 key, 1 rune/soul 
 
Guardian Angel – 3 red hearts, 1 eternal heart, 1 penny, 2 keys, 1 bomb 
 
Lil’ Brimstone – 4 soul hearts, 2 pennies, 1 nickel, 1 bomb 
 
Rotten Baby – 1 soul heart, 1 penny, 3 nickels, 3 bombs 
 
 

Late-Game

 
Okay, so you reached end-game, you’re probably vibing in Cathedral / Sheol / Corpse, or you’re moving your way back up to the beast. This is where you can either do the dirty Bait & Switch or go beat the bosses as Tainted Cain. 
 
_______________________________________________________________ 
 
Pretty much keep going how you are, focus on your build, or just bulk up and let the army of familiars do the work! This is entirely your call now! 
 
 

Switching to Other Characters

 
The Bait & Switch 
Okay so you are going for unlocks for other characters, you are going to want to craft some things before you go for The Clicker. 
 
Step 1: The Battery 
You are firstly going to need The Battery, the reason being is you need two, full charges on The Clicker so you don’t get stuck as Tainted Forgotten. 
 
The Battery is cheap so don’t stress: 
3 red hearts, 1 soul heart, 4 pennies OR 4 pennies, 1 nickel, 1 key, 2 bombs 
 
Step 2: Battery Pack (OPTIONAL) 
Okay, now you have 2 charges, it’s time to get some batteries spawning, you can do this by crafting the Battery Pack: 
6 red hearts, 2 pennies OR 4 red hearts, 3 pennies, 2 keys 
 
Step 3: The Clicker 
Here’s how you switch to another character, although you will lose 1 item per transformation, so maybe craft a bunch of Breakfastor other trash items so you can keep the good stuff! 
 
The Clickeris crafted cheaply and easily, and using the batteries you can get to your desired character easily! 
 
The Clicker: 
3 red hearts, 1 penny, 2 keys, 1 bomb, 1 pill OR 2 red hearts, 2 pennies, 2 nickel;s, 1 key, 1 bomb 
 
_______________________________________________________________ 
 
It’s useful to note that using the clicker can actually be really helpful, for example Tainted Lazarus will not switch to his Dead form, meaning you do not have to deal with that BS! 
 
All in all, EZ win!
