Offense, Defense, Armor, Resists bars

The stats tab will now state your Offense, Defense, Armor, and
Resistances in real time. Accounts for all offense and defense
modifiers, changes in HP and skill levels, factions, shifts in faction
powers, and all resistance changes.

Your Offense is your offense rating with your equipped weapon.
You can, for example, cast Eagle Eyes and see no change
in offense. Why? You don't have a bow equipped. Eagle Eyes
only helps bows. It will update when you equip a bow.

Your Defense is your current defense rating, accounting for
worn armor, faction, skills, and all defense modifiers. You
will see it drop dramatically when you are held.

Your Armor is the sum of all damage reduction from your 
items and Armor of Gort. Armor is not a flat -X damage, it
is a roll between 33% and 100% of its full value for each
strike. An armor rating of 10 will protect between 3 and 10
per hit, average 6. Armor of Gort has different behavior,
and its armor is only counted if the damage cap it brings
is not better than its own absorption. (Ex: a hit of 5 damage
will be reduced by Gort's armor. A hit of 30 damage will
be capped to 15 before armor by Gort, but it will NOT also
absorb  a few points in addition to the cap, it does not pull
double duty). Also, armor is less effective against
partially magic attacks, such as touch spells or qor ded
weapons. It will only protect 2/3rds of the rolled value for
that strike. So 10 armor could start as low as 3, and go
down to 2 against a qor ded attack. Or it could roll 10
and only protect by 6 against a qor ded attack. These
types of attacks will be mitigated by up to 40% by
Resist Magic, or far more than that by the appropriate
resist buff.

Your resists are exactly what you think they are. 20% resist
will reduce that damage type by 20%. A negative value
will increase final damage by that amount. Weapon resist
and Magic resist are the generic resistance types. Only
the best resistance will be used against an attack.
If you have 25% Magic resist and 75% Fire resist,
you will resist a blast of fire by 75%, not by 100%.
If you have 5% Weapon resist and 10% Pierce resist,
you will resist arrows by 10%, not by 15%.

A Qor dedicated bow will fire arrows that are Weapon,
Pierce, Magic, and Unholy. If you have 5% Weapon resist,
40% Magic resist, 10% Pierce resist, and 65% Unholy resist,
you will resist that attack by 65%.
