Each monster has a value given for each of the above attributes. A higher number
in a given attribute represents a weakness towards that attribute. A lower
number represents strength and resistance towards that attribute. Neutral is
defined by the value of 100. Values above 100 indicate weakness while values
below 100 indicate strength. A value of zero (0) indicates immunity to that
attribute.
For example, if a monster has Fire at 75 and Ice at 150, it would only take 75% damage from
fire based attacks, but 150% damage from ice based attacks.
The numbers for the Status Attributes indicate how likely that particular
status is to affect the monster when cast upon it. So you are not very likely
to put a monster to sleep that has the Sleep status attribute at 25.
Finally, the percentages next to the item drops represent the percentage chance you have
of acquiring that item at the end of a battle.
