===== Threshold =====
Some monsters have a very tough hide that will allow them to ignore attacks that do less than or equal to a specified amount of damage. A monster with a threshold of 10, for instance, would only be affected by damage of 11 or more.
If you are striking the creature, the Cast will tell you “[[No Effect]]” to indicate that you are hitting it but do not seem to be hurting it. If you can exceed the limit of the hide, then the creature will take full damage from your blow.

A [[Killing Blow]] can always go through a Threshold. Spell Defenses and suits of armor are affected by all blows, even if the creature wouldn’t normally be affected if its [[Body Points]] were being hit.

Some monsters may even have a “reverse threshold” where any damage above a certain amount has no effect.
