There could be an issue when allowing arbitrary XBetza move footprints as blastZone, though: sould it have an absolute orientation, or be relative to the move of the burning piece? The rudimentary description used now was absolute; the Fire Dragon in Minjiku Shogi had a Q move, with an F burn, and burned diagonally no matter how it moved. But then you could not specify an Advancer with this.
A spellZone can only have absolute orientation, as there is no move to relate it to.
I guess c and d in the final step should be interpreted as to which side would be affected by the spell, not as what the current occupancy of the board should be before the move to be under the spell. E.g. a brake spell must affect empty squares to fullfil its function. So the marking of spell squares should use contingency planning, and tell what would happen should a piece of a certain type appear there.
