All Equipment Stats in Iron Soul Dungeon Guide

Equipment is one of the most important progression systems in Iron Soul Dungeon. While higher rarity gear provides better base attributes, the real power comes from its equipment stats, commonly known as substats. Learning what each stat does and which ones are worth keeping can dramatically improve your character’s performance in dungeons, boss fights, and endgame content. This guide explains every equipment stat in Iron Soul Dungeon, what each one affects, and which stats you should prioritize for the best builds.

What Are Equipment Stats?

Every weapon, armor piece, and accessory can roll additional attributes called substats. These bonuses increase your character’s offensive power, survivability, or overall utility. The quality of your equipment isn’t determined only by its rarity. Two identical pieces of gear can perform very differently depending on the substats they roll. Because of this, farming equipment with strong stat combinations becomes one of the main goals during mid and late-game progression.

All Complete List of Equipment Stats

Below are all currently available equipment stats in Iron Soul Dungeon.

HP Bonus

HP Bonus increases your character’s maximum health pool. Having more HP allows you to survive stronger enemy attacks, making difficult dungeon runs much safer. Tank-oriented players and beginners can benefit greatly from stacking additional health until they obtain stronger equipment.

Attack Bonus

Attack Bonus directly increases your base attack power. Since nearly every offensive skill scales with your attack, this is one of the strongest damage-increasing stats available. Most DPS builds should prioritize Attack Bonus whenever possible.

Critical Rate

Critical Rate increases the chance for your attacks to land critical hits. Higher Critical Rate results in more consistent burst damage. However, once your Critical Rate reaches 100%, additional investment provides no extra benefit, making it important not to exceed the cap.

Critical Damage

Critical Damage increases the amount of extra damage dealt whenever a critical hit occurs. This stat works exceptionally well alongside high Critical Rate. Players focusing on maximizing DPS should balance both stats instead of stacking only one.

Skill Damage

Skill Damage increases the damage dealt by your active abilities. Characters that rely heavily on abilities rather than normal attacks gain excellent value from this stat. It becomes increasingly important for builds centered around powerful skill rotations.

Ultimate Charge Rate

Ultimate Charge Rate speeds up how quickly your Ultimate ability becomes available. Using powerful Ultimate skills more frequently can significantly increase both damage output and survivability, especially during long dungeon fights or boss encounters.

Cooldown Reduction

Cooldown Reduction shortens the waiting time between skill uses. Shorter cooldowns allow you to maintain higher damage output while improving overall combat flow. This stat becomes especially valuable on characters with strong active skills.

Movement Speed

Movement Speed increases how quickly your character moves throughout the battlefield. Although it doesn’t directly increase damage, better mobility helps avoid dangerous attacks, reposition faster, and clear maps more efficiently.

Best Equipment Stats for Damage

If your goal is maximizing DPS, these stats should usually be your highest priority.

1. Critical Rate

Reach close to 100% Critical Rate without exceeding the cap for consistent critical hits.

2. Critical Damage

Once your Critical Rate is reliable, increasing Critical Damage offers one of the largest overall damage boosts.

3. Attack Bonus

Attack Bonus strengthens nearly every attack and skill, making it an excellent all-around offensive stat.

4. Skill Damage

If your class relies on abilities, Skill Damage becomes another top priority after optimizing your critical stats.

Best Equipment Stats for Survivability

Players who prefer safer gameplay should focus on defensive and utility stats.

Recommended priorities include:

• HP Bonus
• Cooldown Reduction
• Movement Speed
• Ultimate Charge Rate

These stats improve survivability without sacrificing too much offensive potential.

Should You Keep Every High-Rarity Item?

• Not necessarily.

Even Legendary or Mythic equipment may roll poor substats. Sometimes a lower-rarity item with excellent stat combinations performs better than a higher-rarity piece with weaker rolls. Always compare substats before replacing your current equipment.

Equipment substats play a major role in determining your overall strength in Iron Soul Dungeon. Understanding how each stat works allows you to build a character that deals more damage, survives longer, and clears content much more efficiently.

For most players, focusing on Critical Rate, Critical Damage, and Attack Bonus provides the strongest foundation for a powerful build. As you progress further into the game, optimizing your equipment rolls and replacing weaker pieces with better stat combinations will become one of the biggest factors in reaching endgame content successfully.
