Proc

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

Mechanics

• PROCs have a 5% chance to discharge per successful meele hit.
• Damage caused by a PROC's discharge is determined using the spell damage formula (determined primarily with intelligence).
• PROCs are affected by power damage modifiers such as the Doomsayer power Vengeance of the Pit and certain class stances.
• Because PROCs do not take weapon damage into consideration, they are most useful on fast weapons such as throwing, unarmed, or daggers.

Strength Tiers

PROCs are classified into three tiers of strength or effectiveness.

• Tier One (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.
• Tier Two (T2) PROCs are available as suffixes on weapons only and are the most common procs found on random drops.
• Tier Three (T3) PROCs are available only in an enchantment suffix. T3 PROCs offer the highest damage or effectiveness for the PROC mechanic that players may enchant on their weapons.

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.

Availability

There are a few ways to obtain a PROC on a weapon:

• 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 enchantments (from the sources above) on a weapon by a player will expire after a specific amount of time (as listed on the source spell's tooltip).
