Sacred 2:Spell Resistance

Spell Resistance

Increases spell resistance against magic spells and additional damage effects such as Burn, Poison, Freeze, Weaken, as well as the chance to evade Critical Hits.

Mastery

• At skill level 75, Spell Resistance reduces the duration of Detrimental Effects and DamageOverTime (unlocks the "Reduction of Detrimental Effects" skill bonus).

Properties

• Protects against Critical Hits caused by spells

The "magic resistance" skill gives the relative (percentage of the current value) lower chance of the enemy critical strike by SpellBasedDamageCA. This means that even the extremely high values of this skill does not give immunity to critical strikes.

Breakpoints

• The bonuses are increased in steps as shown in the Spell Resistance full table.

The Spell Resistance bonus at a given skill level x is given fairly precisely by the following formulas:

• 400*(x+1.5)/(x+100) Pre-Mastery
• 600*(x-32.5)/(x+66) Mastery

The Evade Critical Hits bonus at a given skill level x is given fairly precisely by the following formulas:

• 80.0*(x+1.50)/(x+21.25) Pre-Mastery
• 85.6*(x-32.9)/(x-19.0) Mastery

The Reduction of Detrimental Effects bonus at a given skill level x is given fairly precisely by the following formulas:

• 99.9 - 85.6*(x-32.9)/(x-19.0) (meaning that the values of Evade Critical Hit and Detrimental Effect Reduction add up to 99.9)

The bold marked numbers are the smallest upper bounds of this progression, which will never at any skill level be exceeded.

As an example, spell resistance at x=75: 75 is the first mastery level, so we take the mastery formula and we have

600*(75-32.5)/(75+66) = 600*42.5/141 = 180.85

This value compared with the table value is a good example of the precision the formulas offer.

Alternate methods of increasing Spell Resistance

• Each point of Willpower adds one point to a character's base Spell Resistance.
• Using weapons or items which have native Item Modifiers on them such as Spell Resistance X% or Willpower.
• Forging Spell Resistance X% or Willpower into a character's item slots.
• An increase in Survival Bonus which will increase base Spell Resistance due to the increase in Willpower.
• Combat Arts which boost Willpower (Grim Resilience, Dragon Familiar) will therefore boost Spell Resistance.

How it works

Spell Resistance is both a stat and a skill. The stat is based on the character's Willpower attribute (so if you have a willpower of 200, you will have a base Spell Resistance of 200 before any other mods are factored in), and it can be increased by a number of means (the +% Spell Resistance mod on items, either native on the item, or forged into items). Spell Resistance is used in a calculation with Spell Intensity (the defender's Spell Resistance vs. the attacker's Spell Intensity), if the defender "wins" or "succeeds" on this calculation, the attacker's spell's damage is reduced by a % (possibly 30%), if the attacker "wins", their spell damage is not reduced at this point (though it will still be reduced by any armor resistances or elemental mitigation).

The Spell Resistance skill gives the defender a greater chance of "winning"/"succeeding" on the Spell Resistance/Spell Intensity check, in the same way that Combat Reflexes gives the defender a greater % chance of "succeeding" on the attack/defence check. The skill also reduces the chance for the defender to take a critical hit from a spell & at Mastery the skill reduces "detrimental effects".

As there is no analogue of the chance to hit % on the character screen, the Spell Resistance skill does not appear to have any effect, but we are informed by the devs that it is working.

If the defender's Spell Resistance exceeds Spell Intensity of the attacker (a player's character would need 2400+ of resistancce against the enemies of level 200+), the damage dealt by detrimental magic effects would be noticeably reduced. It works only against CAs that deal flat damage and have a chance for detrimental effects. If an attack inflicts such effect (for example, Burn effect from a Dragon's fireball or Poison from Kobold Shaman's projectiles) then the duration of effect on highly resistant character would be reduced to 1 second and the damage dealt by the one remaining pulse would be divided by 6. Therefore the detrimental effect deals only 4% of its original damage.

At level 75 it makes the duration of DoT and Detrimental effects 35% of original value and decreases it further when the skill level is increased. Damage dealt by these effects is decreased proportionally to the time decrease. For example, if incoming DoT was to inflict 250 damage for 5 seconds it would be decreased by Mastery of Spell Resistance to two seconds - 250 damage dealt by the first pulse and 187 damage a second later, summing up to 437 damage which is 35% of initial 1250. Spell Resistance does not affect negative effects like Stun (as it is not considered a detrimental magic effect). Stun duration can not be decreased by any modifiers. It is a constant value defined by DurationStun parameter in balance.txt (default value is 300 which is equal to 3 seconds in game).

Characters, investing skill points into willpower attribute and holding the value of "magic resistance" skill at the highest possible level, receive from SpellBasedDamageCA only (0.7*1.04)/(1*1.2) = 60% of that damage, which receive characters, ignoring willpower attribute and "magic resistance" skill.
