Overview

Rotting Fissure belongs to the original Sunder Charms, which alter resistance mechanics by breaking immunities. This allows poison-based builds to remain effective even against highly resistant enemies.

Unlike the newer Latent Sunder Charms, this version does not support the upgrade system and cannot be transformed into a stronger variant. It remains a standalone charm designed for immediate use.

Players looking to progress further can obtain a Latent Rotting Fissure, which can later be upgraded into a Renewed Rotting Fissure through the Horadric Cube.

Usage

This charm is especially valuable for builds that rely on poison damage over time. It allows consistent damage application in areas where poison immunity would otherwise prevent progress.

Rotting Fissure is particularly effective in sustained damage setups, helping maintain pressure against enemies in both standard and high-level content.

Why It’s Valuable

+ Breaks poison immunity on enemies
+ Essential for poison-based builds
+ Enables consistent damage over time
+ Immediate usability without upgrades
+ Clear progression path into Latent and Renewed variants
