Touch
The Touch Defense represents your ability to completely avoid physical contact with another creature. Similar to Armor Class, when calculating your Touch score, use your Dexterity Accuracy (DexA). The Touch defense gains no benefit from armor and shields, however, but still suffers the penalty imposed by the Attribute Reduction from any armor that you are wearing.
Combat Training in “Parry” grants a flat bonus to Touch while you are wielding a weapon and represents your ability to parry a creature's attempts to touch you.
In summary, to calculate your Touch defense use the following equation:
Touch = 10 + [DexA - Armor Attribute Adjustment (min. 0)] + Parry Combat Training + Shield Bonus + LVLM + Miscellaneous Bonuses
