One of the tougher bosses in the PS3 version of Demon’s Souls was the Penetrator due to its high speed, aggressive attack style, and powerful attacks. In the PS5 version, the Penetrator seems to have been nerfed a bit, because he doesn’t hit as hard as we remember. Nonetheless, it’s no easy fight by any stretch, and in this guide, we’ll show you how to take it down as effectively as possible.
If you’re a spellcaster, you’ll have a much easier time dealing with the Penetrator because your attacks will absolutely shred through the boss’ armor. Magic like Homing Soul Arrows or Soul Ray will demolish the Penetrator, along with flame spells like Firestorm. Even if you don’t have magic, it’s a good idea to imbue your weapon with Sticky White Slime to deal extra damage.
The strategy to use if you’re a spell caster is to stay at mid range and cast your magic upon the boss, while using the pillars as cover from its lunge attack. The Penetrator will use this attack to close in on you, but if you use the pillars, you’ll be safe.
Keep in mind, if you do need to take cover behind the pillars to heal, the Penetrator can destroy them, so you’ll need to migrate to another one afterward. Luckily, there are several pillars to hide behind.
Then, roll away, cast more magic, and repeat the process. If you are going to use this method, bring the Kris Blade and the Ring of Magical Sharpness with you to boost your spellcasting damage. Remember to stay away from the boss so you don’t get hit with its melee attacks.
Pummel the Boss With Melee Attacks
The other method is to use a melee weapon to take down the Penetrator and it works surprisingly well. As always, stay behind the boss, get a few hits in and then evaluate his next move. If he starts to spin, put up your shield to block it (or roll away), and then circle around the side to continue striking.
It’s possible to fight the boss without a shield, freeing you up to dish out two-handed attacks with your weapon. While this is effective, it’s certainly more dangerous and requires you to be quick and nimble on your feet. To be safe, use a shield that defends against 100% physical damage like the Tower Shield or Steel Shield and block when you aren’t attacking. If you stay right on the boss and play it cautiously, you can take it down with few issues.
As with many strategies we’ve covered, you can mix and match the two methods above. Our character is a melee/spellcaster hybrid, so we used both to take down the boss quickly. If you start the fight by using Homing Soul Arrows, you’ll immediately deal high damage that can be followed up with melee attacks. Keep spamming the Homing Soul Arrows as you strike with your sword and the boss will go down in no time.
