More New Special Abilities

Displacer
A character with this property get the option to swap positions with one other character each combat round before the combat round starts. Usually formation changes only take place at the end of the combat round.

A bit more complex to implement, and it uses up another precious button on the combat options widget. But worth it for a fun special ability.

The Shugenja class gets this ability. I usually picture the Shugeja class as something like the spy Dakuan from Ninja Scroll. Finally the class has a special ability that captures that sort of vibe. He disappears... an interesting tactic.

Parry
Simply a modifier expressing a % chance to parry a melee attack, works as long as the character is armed with a melee weapons. The Shugenja gets this one, perhaps Knave will too.

Melee Master
Grants the charater +1 attack rate for every foe present. The Hero character class gets this ability, who else? One man faced by seven will always win.
