Evade
Evade, a part of the Evade/Block/Parry defensive system against physical and bolt attacks, is a form of defense that will activate before a character makes a combat roll. With a successful evasion the attack will completely miss the target. Even if an attack is successful, evade still contributes to a character's overall defensive strength which acts to reduce damage from an attack. The possibility of evading an attack is increased through training in the dodge, agility and intuition skills, and maintaining low encumbrance, among other factors. Shields and most armor make it more difficult to evade an attack, especially larger shields and heavier armor.
The Dodge skill is a primary factor in avoiding an attack entirely. While in stance offensive, a character, singled (1 rank per level) in dodge, has approximately a 5% chance of evading an attack against a like-level foe. A character double trained (2 ranks per level) has a 10% chance and a character triple trained (3 ranks per level) has a 15% chance for an outright evasion. These percentages increase as a character moves to more defensive stances. The chance of an outright evasion also depends on a character's agility/intuition skill bonuses, encumbrance. Certain spells such as Mass Blur (911), Mobility (618), Song of Mirrors (1019), and the combat maneuvers Evade Mastery (available to warriors, rogues and monks) and Duck and Weave (available to rogues and monks) will also improve the chance to evade an attack.
There is no available formula to determine the exact chance that an attack will be evaded, but level of the defender vs level of the attacker is an important factor. Also, weapons and bolts are harder to evade than melee attacks, even though there's a DS bonus against such attacks.
Evade DS Formula
The first step in determining the evade DS bonus is to calculate the Base Value.
Dodge Ranks + (Agility Bonus) + trunc(Intuition Bonus / 4) = Base Value
The second step is to enter the Base Value into the Evade DS formula along with the value of the other factors (see lists below).
Base Value × Armor Hindrance × Shield Penalty × Stance Modifier = Evade DS
Note 1: Truncate results to integer values after each operation in the formula.
Note 2: There is a 50% bonus to the evade DS against ranged attacks. (Evade DS * 1.5)
Example
The Evade DS for a character with:
- Dodge Ranks: 60
- Agility Bonus: 20
- Intuition Bonus: 18
- Armor: Brigandine Armor (.94 factor)
- Shield size: Medium (.70 factor)
- Stance: Advanced (.80 factor)
Step 1 (Base Value) Calculations:
60 + 20 + trunc(18 / 4) = 84 Base Value
Step 2 (Evade DS) Calculations:
84(Base Value) × .94(Armor Hindrance) × .70(Shield Penalty) × .80(Advanced Stance) = 43 DS
Without truncating after each operation there would be an incorrect result of 44 DS.
Armor Hindrance Factors
The Armor Hindrance values to be used in the formula are:
- Normal clothing (AsG 1): 1.00
- Robes (AsG 2): 1.00
- Light Leather (AsG 5): 1.00
- Full Leather (AsG 6): 1.00
- Reinforced Leather (AsG 7): 0.98
- Double Leather (AsG 8): 0.97
- Leather Breastplate (AsG 9): 0.97
- Cuirbouilli Leather (AsG 10): 0.96
