Armour Class In Slash'EM

There are several factors contributing to the player's armour class in Slash'EM that don't apply in vanilla Nethack. Here is a summary of how to calculate your AC in Slash'EM. First the factors that exist in vanilla Nethack:

• Your base AC (10 if you're in your normal form).
• Subtract the AC values of your armour.
• Subtract the AC bonuses from worn rings of protection.
• Subtract any intrinsic protection.

Now the factors that only exist in Slash'EM:

• Subtract any temporary protection from casting the protection spell.
• Dexterity affects your AC as follows:

• If you are a Monk and are not wielding a weapon, wearing a shield, or wearing body armour other than any kind of robe, subtract a natural protection bonus of 11 if your experience level is at least 18, and 2 plus half your experience level otherwise.
• If you are a Doppelganger or Lycanthrope and are not wearing any body armour (even robes), subtract a natural protection bonus of 1 plus 1/4 of your experience level.
