Build Guide

• Support Effect: It supports melee attack skills, causing them to gain a percentage of physical damage as extra fire and lightning damage.
• Excommunicate Debuff: Hits from supported skills apply the Excommunicate debuff to enemies.
• Excommunicated enemies cannot deal Chaos Damage. This is a powerful defensive tool against bosses or monsters with high chaos output, though it does not prevent the player from taking chaos damage from other sources (e.g., ground effects or self-damage).
• Direct Use Only: It does not modify skills used by minions.
• Alternative Sources: The Hand of Heresy unique gloves also provide the ability to Excommunicate enemies on melee hit without requiring the support gem.

Related: Excommunicated

Excommunicated is a debuff that causes affected targets to be unable to deal chaos damage.

This only affects damage coming from the afflicted target. If another user has a damage taken as modifier that converts damage taken into chaos damage and takes damage from an Excommunicated enemy, they will still take chaos damage from that conversion.
