*Rules: "Units guarded by a friendly unit are paralysed and lose all their powers, including the power of paralysing further friendly units (note the difference from Madrasi). Kings neither paralyse nor are paralysed. Reciprocal or cyclic guards do not paralyse unless one of the units is also paralysed from outside the cycle".
