Shadow wx should be able to use unique fuels to enhance its capabilities

[whiteking]

Nightmare fuel can only burn for 30 seconds without any additional functions, and cannot restore any power during the burning period. It can only be used as an emergency shelter (if you have just been resurrected or are facing rain). If you cannot quickly find a way to restore power, you will need to consume 16 Nightmare fuels per day until you are out of danger.
So it is entirely possible for wx to obtain 1 to 2 additional slots, which cannot be charged in any conventional way and can only be used when burning nightmare fuel. If these slots are to be activated, a large amount of nightmare fuel must be consumed every day.
Of course, there are many other options, such as increasing the power of the circuit, making the lighting range slightly larger, running faster, and rotating faster.
When he has a heart, this fuel can give him extra attack power.
Restrictions can be added, such as excessive nightmare fuel causing wx to lose sanity and being controlled for a few seconds like facing a Shadow Boss

I agree this is a cool idea. good way to add in some sort of overcharm mechanic.

Maybe instead of being limited to two notches, you can equip a bonus circuit regardless of the notches, or type. But, the more notches it has the bigger the downsides/costs of doing it.

I think they should add permanent charge each one. And pure horrors would add 2 charges. 

Or make it soo new effects are added while being overcharged with nightmare fuel. And pure horror has double the duration and strength. And the effects don't stack. Only the duration
