Generic Chess Piece Creation System

This is a system for construction of pieces, with some roots in Buypoint Chess and A Chess-like Variant Construction Set. This one, however, is intended to be much more freeform, bringing ideas from RPG games.

Base Piece

The base piece costs 10 points for each square it occupies. A piece like this can't move, capture or do anything deserving of respect: It just stays there and can be captured. You'll probably want to buy some Moves for the piece.

Moves

Second, you can buy Moves, which define the mobility of the piece. Each Move has its base cost that is added to the value of the piece. A Move can be boosted beyond its basic status via Advantages and Limitations, which will alter its cost. First, to the Move cost: 
Move type	Cost	Description
Orthogonal	3	Moves one square in a single orthogonal direction
Diagonal	2	Moves one square in a single diagonal direction
Leap		2	Combination of orthogonal and diagonal moves (1/8 of a Knight 
move)
Composite	X	Sequence of moves in a row, bought as a single move
Extra 		X	Extra moves (see in special box)
Leap Moves: A combination of orthogonal and diagonal moves. 2 points each. A combination of 8 leap moves (reflections and rotations), like a Knight move, costs 16 points.

Composite Moves: A sequence of moves the piece does (Like the Crooked Bishop, that does two Diagonal moves in a row). Add the move points of all the moves in the sequence. The piece can stop anywhere in the composite move. Each part of the composite move can have its own advantages and limitations!

Extra Moves: Things that didn't fit here. See below.

Advantages and Limitations

Each move or group of moves can be stretched with the use of these, altering its base cost: For example, a group of the 4 Orthogonal moves can be bought with Repeat Infinite, turning it into the basic Rook move. 
Repeat N 		*N	Can repeat the move N times
Repeat Infinite		*5	Can repeat the move indefinitely
Leap 			*2	A leap move can leap over other pieces
Leapwalk 		*4	The piece can repeat its move over other pieces
Dual Move 		*4	Can move twice
Dual Strike Move	*8	Can move twice, capturing on both moves
Tri Move 		*16	Can move three times
Tri Strike Move 	*32	Can move three times, capturing on all moves
Pusher			*X	Pushes (x-1) enemies on the line
Momentum		*2	Keeps repeating move while possible

Leap Capture		*2	Leap move captures piece it leaps over, stops (unless 
Unstoppable)
Approach Capture	*2	Attacks enemy piece by approaching
Sandwich Capture	*2	Attacks enemy piece with another friendly piece after 
it
Retreat Capture		*3/2	Attacks enemy piece by retreating
Rifle Capture 		*3	Can capture an enemy piece without moving

Doesn't Capture 	/2	Can't capture in that direction
Doesn't Move 		/2	Can't move without capturing in that direction
Unstoppable		*3	Can capture a piece without ending its turn
Single Chance Move 	/4	A move that can only be taken once in the game
Must Leap & Stop	/2	Must leap over a piece, lands on the square after it
Only Threatened		/2
Only Not Threatened	/2
Kamikaze		/4	Kamikaze Move: Piece is sacrificed after its end
Some pieces not only move, but have special abilities: They attract other pieces, repel them, destroy them... Those pieces have Powers.

Powers

Powers are special abilities of pieces. The powers can be Passive or Active. Active powers only work when the piece moves or captures. Passive powers act at the end of every turn.

The power base cost is just as a move base cost, representing the squares the power can affect. Apply the modifiers below for the specific type of power: 
Attraction		*1	Attracts friendly OR enemy pieces
Repulsion		*2	Repels friendly OR enemy pieces
Magnetism		/2	Repels friendly pieces, attracts enemy pieces
AntiMagnetism		*1	Repels enemy pieces, attracts friendly pieces
Conversion		*2	Changes friendly OR enemy piece's allegiance
Poison			*2	Poisons friendly OR enemy pieces
Movement Gift		*(1/10)	Grants extra movement to friendly OR enemy pieces 
- cost is 1/10 of the move
Power Gift		*(power)Grants extra powers to friendly OR enemy pieces - cost 
equals power cost
Immobilization		*2	Immobilizes friendly OR enemy pieces
Burn			*3	Destroys friendly OR enemy pieces

Modifiers

These affect the nature of the power.

Passive Power		*2	Power is always activated
Chaos Power		/2	Skills are granted to all pieces, not just friendly OR 
enemy ones
Example: The Fiery Dragon has the Passive King Burn. King move is 20 points. Burn is *3, and Passive is *2. The total score is 20*3*2=120. Plus the Bishop movement of the Dragon gives a grand total of 170.

Extra Moves

Moves that change with time: 'Special' moves. Can be bought more than once, and can be bought with the move advantages and limitations. 
Mimic			50	Mimics any pieces (protecting/attacking) it
Imitator		50	Imitates a certain piece
				- Last (any/friendly/enemy) moved piece
				- Last (any/friendly/enemy) captured piece
Assimilate		30	Mimics last piece it captured
Metamorph		30 or average of all move types, whichever's larger
				Move depending on column/row piece is in

Piece Modifiers

After buying all moves and stuff, you can apply these modifiers to the final cost: 
Colorbound Piece	-5	Can only walk on one color of the board (Diag)
1/4 Bound Piece		-10	Can only walk on 1/4 of the board (Orth2, Diag2)
Can't Capture		-10	Can't capture, ever
Can't Be Captured	*5	Can't be captured, ever
Promotes		+5	Promotes
Reproduces		*3	Can reproduce
Spins			*2	Can spin in place, changing direction marks
Spawner			+(point cost*2)	Spawns other pieces
Royal			*5	Losing all loses the game
Checkmate		*2	Can only be captured by checkmate
Poisoned		*3	Piece that captures this piece is also captured
