Stats post, folks! I'll keep this updated as the battle goes on.

Important battle notes
Again, subject to change as more information is known

• Characters take Double damage if they cast a spell that turn.
• Characters take Half damage if they are defending that turn.
• Characters take Normal damage if they both cast a spell and defend in the same turn.
• You can move diagonally. Diagonal moves do not cost extra.
• Dead people obstruct movement.
• We can only cast one spell per turn. Spells may be targeted anywhere and do not require line of sight.
• Magic immunity does not prevent the use of items (e.g. First Aid Kit).
• Grouped characters (e.g. A/L) attack together and take damage together.
• Attacking counts as a move, and ends movement.
• You cannot defend and move in the same turn.
• Spells that reduce the movement points required for attacking allow you to attack more than once.
• You can move the same turn you are Raised.
• Raise, Animate Dead, Feat and the First Aid Kit are not affected by magic immunity.
• Summons cannot cast spells the turn they are summoned.
• You can't cast the spells of someone you've hypnotised.
• Antimagic can't be dispelled.
• The dark squares on the side of the map are bottomless pits

The battlefield changes in size during the battle as follows:
Turn 1: stay at 5 tiles wide
Turn 2: shrink to 3 tiles wide
Turn 3: shrink to 1 tile wide
Turn 4: grow to 3 tiles wide
Turn 5: grow to 5 tiles wide
Turn 6: shrink to 3 tiles wide
Turn 7: shrink to 1 tile wide
Turn 8: grow to 3 tiles wide
Turn 9: grow to 5 tiles wide
... and so on
This happens at the end of each turn.

Right, I think that's all. Feel free to correct me if I've missed something out or made a mistake.
