While I am slowly building a set of static pages to describe the rules I am developing for my slightly eccentric approach to the Celtic Fringe games I play, I also what to start posting many of the game mechanisms. The page on Other Reference Rules lists some of the more important rules sets that have influenced my thinking. Far and away the most influential is Flashing Steel from which I have liberally borrowed. I am also heavily influenced by boardgame mechanisms and in many ways what I do is probably more boardgame-like than not.
Combat Pieces (along with Command Pieces) are formed into units that operate together but the way units move is controlled by the way individual combat pieces move. Since the game is played on an imaginary grid (orientated to the board edges), a combat piece may have only four facings:
One action (of a possible three) is expended to change the facing of a piece.
Movement is by “sticks” of which there are four: Short(|), Medium(||), Long(|||), and XLong(||||) in the ratio 3:6:8:10. The length (or width) of a standard combat piece base (1″ or ~25mm) represents a fifth possible move (XShort). The movement of one stick requires the expenditure of one action:
The stick represents the maximum distance the piece may move with a single action, it need not move the full distance but a full action is still expended. As illustrated above the measurement is from the front edge of the piece to the rear edge of the piece in the new position (thereby gaining an XShort addition to the move). All movement must be on the straight line indicated by the stick
A combat piece may make an oblique move (keeping its facing) up to 60 degrees to the left or right of its front edge. As shown below the movement is measured corner to corner for the oblique move:
A combat piece may use all of its actions in movement (up to three actions may be possible). Since movement must be in a straight line, the sequence below shows how a piece could use three consecutive action to navigate around an obstacle (one straight and two oblique):
Obviously many other combinations of facing changes and movement can be assembled.
Foot (and only foot) combat pieces may make an additional type of move – a lateral or rearward move performed while maintaining the same facing:
This move is always measured with a one step reduction from the standard move for that piece (in this case Medium(||) reduces to Short(|) ). This move is always parallel (lateral) or perpendicular (rearward) to the current position with no oblique adjustment permitted.
