Item effects

Many items in Resurgence grant special skills or effects - some of which are not otherwise available to players. These range from completely new attacks and spells, special trigger effects, timed buffs, unique auras and the familiar triggered skills (such as 5% Chance to cast Level 1 Amplify Damage on Striking).

## Class skill effects

This section applies to the following properties, when [Skill] is a skill that exists on a class' skill tree:

* X% Chance to cast Level Y [Skill] on Striking
* X% Chance to cast Level Y [Skill] on Attack
* X% Chance to cast Level Y [Skill] on Kill
* X% Chance to cast Level Y [Skill] on Kills with Attacks
* X% Chance to cast Level Y [Skill] when Struck
* Grants Level X [Skill] Aura when equipped

The damage of class skills granted or triggered by items is calculated differently than when the skill is used actively by the player. Calculating damage dealt by these skills can be done by following the two new rules:

1. The **base** damage of a skill cast by an item is equivalent to the fully-synergized version of the class skill.
2. Synergies still apply to this boosted base damage, but at only 10% effectiveness.

As an example, you may find an item with the property "10% Chance to cast Level 28 Fireball on Striking". If you were to cast Level 28 Fireball as a Sorceress, it would have a base damage of 334-476 that will then be boosted by synergies of 20% from Immolate and Meteor. To calculate the base damage for Fireball as triggered by an item, we calculate the damage as if the skill was fully synergized (20 skill points into both Immolate and Meteor):

```
ITEM_BASE_MIN_DMG = 334 * ( 100 + 20*20 + 20*20 ) / 100 = 3006

```

```
ITEM_BASE_MAX_DMG = 476 * ( 100 + 20*20 + 20*20 ) / 100 = 4284

```

Therefore, this Fireball trigger effect base damage is 3006-4284. This damage can be furthered increased by +% Fire Damage modifiers or if you are a Sorceress, any points into Immolate and Meteor will increase this base damage through the synergies (though at 10% effectiveness). For example, if you are a Sorceress who has put 16 puts into Immolate and 7 points into Meteor, the final triggered skill damage will be (ignoring any sources of +% Fire Damage such as Fire Mastery):

```
ITEM_FINAL_MIN_DMG = 3006 * ( 100 + 16*20/10 + 7*20/10) / 100 = 4269

```

```
ITEM_FINAL_MAX_DMG = 4284 * ( 100 + 16*20/10 + 7*20/10) / 100 = 6083

```

In this instance, having the item trigger Fireball for 4269-6083 damage is quite a lot larger than the 1870-2667 damage (334-476 base damage with listed synergies) it would deal if you casted it yourself! However, keep in mind that such triggered skill properties are rare and normally have low chance to cast probabilities to balance out their high base damage.

In general, the formula for calculating triggered skill damage is:

```
ITEM_BASE_DMG = CLASS_BASE_DMG * ( 100 + 20*SYNERGY1 + 20*SYNERGY2 + ... ) / 100

```

```
ITEM_FINAL_DMG = ITEM_BASE_DMG * ( 100 + S1P*SYNERGY1/10 + S2P*SYNERGY2/10) / 100

```

Where "SYNERGY1, SYNERGY2, ..." are the % skill damage bonuses granted by that synergy skill and "S1P, S2P, ..." are the skill points that have been put into synergy 1, synergy 2, ... skills respectively.

## Special or dynamic effects

This section applies to prominent or important properties that do not necessarily fit in any of the other categories.

**Melee splash:** Deals damage in an arc in front of the attacking character whenever a melee skill is used. The damage dealt is equal to Basic Attack damage, meaning it does not benefit from skill-specific damage modifiers (such as Zeal's +% Damage or Fire Claws' 50% of Damage converted to Fire). However, properties such as lifesteal, crushing blow (with ranged penalty), added damage from items, enhanced damage from items do apply. This effect specifically requires a melee attack, meaning pseudo-melee skills such as Amazon's Ground Slam or Druid's Shockwave do not generate melee splash.

**Fortify:** For 2 seconds, grants Physical Damage Reduction (PDR) and Magic and Elemental Damage Reduction (MDR) via the following formulas:

```
PDR = (lvlxlvl)/80 + lvl/4), [+100 at clvl80]

```

```
MDR = (lvlxlvl)/10 + lvl/3, [+667 at clvl80]

```

**Elemental Volatility:** Increases to Elemental damage also grant Elemental pierce at 20% of their value.

**Elemental Adaption:** Increases to Elemental damage also increase your Elemental Resistance

**Elemental Destruction:** Passive elemental penetration can break immunities.
