- Damage to equipment.
This game is not like wow or any other mmorpg in which the goal is to gear up a player.
Armours tend to break, crack and become in need of repairs.
And if you neglect that, then they get destroyed beyond repair.
- Killable nobles.
Although killing counts and dukes was not advised as the ransom money was a good income for a medieval force, it doesnt mean that they were never ever killed.
- Kill/Knock out distinction.
A sword does not always kill, and nor can you survive a mallet in the size of a child to the head.
