Proc

PROC is an acronym for "programmed random occurrence." In Shadowbane, "proc" refers exclusively to an enchantment associated with a weapon that bestows a five percent chance per swing to discharge spell damage or damage-over-time against the wielder's combat target.

Mechanics

A proc only has a chance to fire on attacks that successfully strike the target with the original physical damage; however, a discharge from a proc will never miss. The damage of a proc discharge is determined using the spell damage formula, associated primarily with intelligence. Procs are also affected by power damage modifiers such as the Doomsayer power, "Vengeance of the Pit".

Tiers of Strength

Procs are classified into three and sometimes four different tiers of damage or effectiveness (however, they will always fire at a rate of 5%). Tier one, or "T1" procs offer the lowest damage and are usually undesirable as a suffix enchantment because there are better ones available. However, prefix enchantments only offer T1 procs (e.g. "Icy Poinard") and are sometimes sought-after. Second tier or "T2" procs are available as suffixes on weapons only and are the most common procs found on random drops. Third tier or "T3" procs are the most powerful that are widely available, and are available only in a suffix . T3 procs offer the highest damage or effectiveness for the proc mechanic that players may enchant on their weapons. Fourth tier or "T4" procs are only available on special weapons that were handed out during Feature Character events, which have been discontinued.

Damage Types

Procs are available in many different damage types, all of which can be resisted and exposed. For example, a Necromancer would experience higher proc damage using unholy procs if he was to cast "Unholy Fright", an unholy exposure debuff, beforehand. Alternatively, if the unholy procs were used on a Shade or a Vampire, the damage would be reduced, as these races have increased resistance to this damage type.

Sources

There are a few ways to obtain a proc:

• Crafted into suffix and/or prefix of a weapon enchantment
• Casted upon it by a Crusader's "consecrate weapon"
• Casted upon it by a Nightstalker's "annoint blade"
• Casted upon it by an Assassin's "poison blade"
• Casted upon it by an Undead Hunter's "consecrate weapon"

While PROC prefixes and suffixes to weapons are permanent, those that were casted as echantments (such as Assassin's Poison Blade) on a weapon by a player will expire after a predetermined amount of time.
