Defense Ratio

Base Value = 2 * Dexterity

add Defense Ratio bonus from items and talents
multiply by percentual Defense Ratio bonus/penalty from talents

Chance to Hit

Probability [%] = Hit Ratio / Defense Ratio * 62

Physical Absorbtion (?)

Base Value = Physical Absorbtion of the single armor piece

Physical Damage (?)

Base Value = Weapon Damage + Strength / 30 (round down)   for Bows with Archery talent
           = 1 + Strength / 20 (round down)               for Hand Attack
           = Weapon Damage                                for other weapons
               
if not using Hand Attack, add 
   Base Value * Strength * 0.002

multiply by percentual Base Weapon Damage bonus/penalty from talents

   1.5  for Short Sword
   1.4  for Long Sword

Magic Attack

Magic attack can deal crushing hit for extra damage.

Mage Level = Adjusted Level / 10 (round result down) 
Circle     = the circle number of the spell you are casting
Penalty  = { 5, 5, 8, 8, 10, 14, 28, 32, 36, 40 }

Magic Hit Ratio

Base Value = Magic Skill

if Magic > 50, add
   Magic Bonus = 1.15 * (Magic - 50)

if Circle < Mage Level, add
   Level Bonus = 5 * (Mage Level - Circle)

if Circle > Mage Level, subtract
   Level Penalty = b - (a / c * b) (round result to nearest)
   a = Adjusted Level - (10 * Mage Level)
   b = (Circle - Mage Level) * Penalty{Circle}
   c = (Circle - Mage Level) * 10

add Hit Ratio bonus from items and talents
multiply by percentual Hit Ratio bonus/penalty from talents

Magic Resistance

Base Value = Magic Resistance Skill

if Magic > 50, add
   Magic Bonus = Magic - 50

add Magic Resistance bonus from items and talents
multiply by percentual Magic Resistance bonus/penalty from talents

Magic Absorbtion (?)

Base Value = Sum of Magic Absorbtion bonuses from items and talents

if hit by elemental magic (fire, ice, earth, lightning),
   add respective Elemental Absorbtion

if result > 84, round it to 84

Magic Damage (?)

multiply by (1 + 0.003 * Magic)
multiply by percentual Magic Damage bonus from talents
add Magic Damage bonus from items
add Damage bonus from monster speciality levels

if crushing hit, multiply by Magic Crush Damage

multiply with target's Magic Absorbtion

Getting Hit

Getting hit cancels your prepared spell.
Getting hit has a high chance of stunning you which plays the hurt animation and delays your action (?)=.

Physical Attack

when hit an armor piece is randomly chosen
   50% Chest Armor
   25% Leg Armor
   15% Hauberk
   10% Helm

the Physical Absorbtion of the armor piece is used to decrease the incoming damage
Endurance of the armor piece is decreased

if a shield is equiped and you are facing your attacker, you have
   10% - 100% (?) chance to block (scaled with Shield Skill), which 
   adds shield's Physical Absorbtion to hit armor piece and
   shield takes 80% of the armor piece's Endurance decrease

Mana Regeneration

Every 20 seconds, you gain
   from Magic/3 to Magic amount of MP

Stamina Regeneration

   3dVitality/20 (round down) amount of SP (whatever that means, its not dice throw, 3d0 gives you 13 every time)
