Izzy, in the game a "block" is deemed an action preventing (or partially at least) the attacking weapon from hitting the player. It does not tell you how perfectly you blocked the attack, and a shield can be broken by blocking any attack, so in IVAN, blocking is actually a simple matter of getting the shield in the way. And accuracy determines your ability to block an attack, not your ability to stop the shield from breaking.
System would indicate in graphic if person is mounted on horse or not.
Same system also show if person mounted on boar, elephant, polar bear etc.
Or if person mounted on ass.
Ivan find mounting on ass funny.
