The Penance Brand of Dissipation Inquisitor is a powerful and popular build in Path of Exile (PoE), especially noted for its exceptional boss-killing capabilities and strong single-target damage. This build revolves around the skill Penance Brand of Dissipation, a variant of the Penance Brand skill that attaches to enemies and deals damage over time, scaling with energy accumulated on the target PoE 1 Currency.

Core Mechanics and Playstyle
Unlike the classic Penance Brand that explodes after reaching 20 energy stacks on a single enemy, the Dissipation variant does not explode but instead lasts for its full duration, dealing increased damage per energy stack. This allows for sustained, high damage output over time, making it ideal for boss fights and tougher single targets.

The build focuses heavily on increasing Brand duration and activation rate, which is often achieved by boosting the player’s cast speed. This lets the brand quickly reach the 20 energy cap in as little as 5 seconds, maintaining consistent damage throughout the fight.

Key Ascendancy and Passive Choices
The Inquisitor ascendancy is favored for this build due to its Inevitable Judgement node, which provides critical strike bonuses and elemental damage boosts, and Righteous Providence for survivability. The build typically aims for high critical strike chance, which synergizes well with the Inquisitor’s bonuses and increases overall damage.

Players often convert about 50% of the Brand’s physical damage to elemental damage, preferably lightning, which can then be further converted to cold for additional utility. The build also benefits from low-life mechanics, utilizing the Pain Attunement keystone to boost spell damage when on low life, and sustaining Righteous Fire for extra spell damage via the Pious Path passive.

Gear and Support
The build is moderately expensive but does not rely heavily on unique items; well-rolled rare gear is often preferred. Popular choices include Call of the Brotherhood rings to chill and freeze enemies, and Heatshiver helmet for increased freeze effect and damage. Defensive layers include Petrified Blood, life leech, and life regeneration to improve survivability.

The Hierophant’s Sign of Purpose passive, often accessed through forbidden jewels, can double Brand damage, significantly amplifying DPS. Players also use Brand Mastery to make brands switch targets frequently, improving clear speed alongside outstanding single-target damage Poe 1 Divine Orb.

Summary
The Penance Brand of Dissipation Inquisitor is a critically strong, hit-based build that excels in boss fights with its sustained, high elemental damage. It combines the Inquisitor’s critical and elemental bonuses with brand mechanics and low-life damage boosts, resulting in a build rated highly for damage, tankiness, and clear speed. While it requires some investment in gear and passive optimization, it remains one of the most effective and enjoyable builds for endgame content in PoE.
