I will answer about dembels, rolevics and Gypsies.

If the Gypsies attack the cavalry, they will become copeys and the Gypsies will become horsemen.

The rolevics are the same Gypsies, but in armor, and without the bonus of theft. They can attack the Gypsies.

It makes no sense to attack someone. They are good to keep as the guard of the castle.
They cast on slowness and stone skin in 99 moves. When trying to attack them, they impose a curse on the enemy for 99 moves. Then they attack in response three times with a thirst for blood.
I want a game like that.
And robbed the crowns.

To all the good, cats and heroes of sword and magic.
