About the mirror. I think the capture of mirror will be illegal if after that it is a check to your own king
on f4 is a mirror. It is illegal to R:f4 because
Also I think that the mirror cannot be captured by the king. Because after that king change color, so it will be 2 white kings. Or 2 black.
The mirror: moves and captures like a knight. Death effect: clone a piece with the same piece that captured the mirror, but not cloning the same color. The capture of mirror will be illegal if after that it is a check to your own king. The mirror cannot be captured by the king. Because after that king change color, so it will be 2 white kings. Or 2 black. The mirror can also capture the mirror.

Why do you guys keep quoting the OP to say one or two lines?
It is a giant text and makes it difficult to read through the discussion.
Please quote just a part of it if possible, not the whole text.
You can edit what you've quoted so to make it smaller.

Are you going to add this?
Spirit I(S) - A spirit moves as a knight. It can 'capture' friendly pieces, which gain the movement of a knight in addition to it's other abilities (knights are not affected, but can be used for transportation. A 'possessed' piece can be captured like normal. A spirit which is not possessing anything can only be captured by a possessed piece. It is transparent to friendly pieces.
can it capture

can it capture it means that it posses that piece. It cannot capture enemy pieces

You mean if you have two spirits? I would be leaning towards no, but I wouldn't want two spirits in a game anyway...

I am just saying I think there are better threads to make piece suggestions as this is for official and tested pieces.

Auk could you please paste this into the first post 🙂 thanks!
- Barrier (Bar)
Invented by @Naviary, believed to be around 15 points.
It moves around exactly the same as a rook, but emits a "Force Field" on all 4 sides. These fields cannot be crossed by hostile pieces in a single move, for if they try they will be forced to stop in the line of fire before they can move past next move. This means in order to cross they have to put themselves in danger first. The field cannot travel through pieces, except "transparent" pieces (i.e. friendly witches & spirits, and pieces adjacent to a friendly witch). Witches can also make adjacent barrier field squares transparent to cross safely! The field has no effect on friendly pieces.
The force field does not prevent pieces with leaping capabilities from jumping over, it only effects sliding moves. Also, any piece can move straight through the barrel of a barrier field without stopping, it's only moves that come in contact at a 90˚ or 45˚ angle that they will be stopped. Hostile barrier fields will also cancel each other out at their point of contact.
I have now added the inventors of each piece but if I got one wrong please tell me (I am sure I have)...
- I myself have invented the Witch.
- The Joker is from Superchess, Henk van Haeringen.
- I did not invent the Zombie.
- The Angel is from Superchess, Henk van Haeringen.
