In RogueBlox, understanding how Armor Penetration works can make a major difference in both PvP and PvE. Whether you’re struggling against high-defense mobs or getting low damage in duels, the issue might not be your weapon—it could be your penetration stats. This guide breaks down everything you need to know about Physical and Magical Penetration, how it affects damage, and how to build around it properly.

What Is Armor Penetration?
Armor Penetration is a stat that helps reduce or “pierce through” an enemy’s armor or resistance. It comes in two types:
- Physical Penetration (Phys Pen) for physical damage weapons and skills
- Magical Penetration (Mag Pen) for magic-based damage and spells
Enemies and players both have armor stats—Physical Armor and Magic Armor—that reduce incoming damage. Penetration counters this. The more pen you have, the more armor you bypass. For example, if a mob has 40 physical armor and you have 20 physical pen, you’re ignoring half of that defense.
How Do You Get Penetration?
Penetration is gained from multiple sources in RogueBlox:
- Outfits and Armor: Your outfit (like ultra armor or class-specific armor) and standard armor both contribute to your pen stats.
- Reforges: Certain reforges like Spiky (Physical Pen) and Arcane (Mag Pen) increase your penetration directly. Reforges can also lower HP or other stats in exchange.
- Passives and Relics: Some gear has passives that grant bonus pen after specific actions, like applying bleed or critting. For example, the Agile enchant and relics like Shrouded Sheath can boost pen further.
Why It Matters in PvE
A lot of PvE mobs have high armor stats, especially late-game enemies. If you’re doing physical damage and you don’t have any pen, your damage will be drastically reduced. Magic users usually have it easier in PvE since many mobs have lower magic resistance—even some mobs have negative magic armor.
But don’t worry if you’re not using a magic build. High penetration can even out the damage gap. A build with 22+ physical pen can turn weak hits into solid damage, even against armored mobs.
What Is Overpen?
Overpen, or Overpenetration, happens when your penetration stat is higher than the enemy’s armor. For example:
- You have 30 physical pen
- Enemy has 20 physical armor
- You’re overpenning by 10
Each point of overpen converts to +1% extra damage, capped at +10%. That bonus applies on top of the fact that you’re already ignoring all their armor. You’ll know you’re overpenning when you see a pink sparkle VFX during attacks.
This applies in PvP too—if you’re facing a player with 30 armor and you’ve built 40 pen, you’re getting the full overpen damage bonus.
How to Check Your Pen and Optimize
To check your stats:
- Open the character menu
- Look for the stat page button and toggle to see Armor, Pen, Speed, etc.
Build optimization tips:
- Use Spiky reforge for Phys Pen or Arcane for Mag Pen
- Stack passives and relics like Shrouded Sheath to multiply speed-based effects and get adaptive pen (boosts both Mag & Phys Pen)
- Combine builds with enchants like Agile that scale over time
Final PvE Example: Pen vs No Pen
In tests against a high-armor mob like Gorian:
- Zero Pen Build: Does very little damage even at ultra class
- 22+ Pen Build (No Weapon): Massive difference in damage output
This proves how impactful penetration is—especially for PvE grinding and progression. If you’re struggling to beat mobs, the issue might not be your power, but your lack of pen.
Yes, penetration is absolutely viable in PvP. While no player can reach mob-level armor (like 80), they can still hit 30-40 armor. If you’re not building any pen, you’re letting them soak your hits easily. A penetration-focused build like World Seeker or Shrine of Ferocity can flip the fight in your favor.
To sum it up: Penetration helps you break through armor in both PvP and PvE Reforges, relics, and armor all contribute to your pen stats, Overpen gives bonus damage on top of armor negation & It’s one of the most important stats to understand and build around! If you’re looking to improve your performance in RogueBlox, focusing on armor penetration could be the missing piece.
