To add to the short list of strong threats in Resident Evil 4 Remake, the Ruthless knight, exactly matches his name. This knight possessed by Las Plagas is incredibly strong. The blue request mission that mentions him instructs Leon to get rid of the monster.
However, before you run into the Mausoleum to fight this knight, there are a few things you need to keep in mind so you don't have to die from the only hit he's known for. Here's how to defeat the Merciless Knight in Resident Evil 4 Remake.
How to defeat the "Ruthless Knight" in Resident Evil 4 Remake
After examining the library as Ashley in chapter 9, you will regain control of Leon in chapter 10. Now Leon can access the library, so go there.
The blue mission "The Walking Dead" can be found at the entrance to the library!
This particular quest challenges Leon to defeat the knight in the Mausoleum, except this guy is a lot stronger than any other Armadur we've come across before.
Once in the Mausoleum, the Merciless Knight is very visible due to his golden armor, will be accompanied by two standard Armadur.
First of all, focus on destroying the standard Armadura so that we can deal with the Merciless Knight alone. Defeat them as you already did, targeting the parasite that bursts out of their helmets. Enough hits and their helmet will drop, giving you more parasites to target.
When these two are killed, focus on the Ruthless Knight. We want to shoot the parasite on the back whenever we have a chance, and your best moment to strike is when he tries to attack us with one blow of his sword, which was mentioned in the blue request. He's a bit clumsy and will wobble between attacks, leaving you with a very opportune moment to strike.
After enough hits, his helmet will also come off, like any old Armadura. We have a lot more targets now, but we also need to focus on avoiding the parasite's whips as well as its sword strikes. Shoot the parasite with all your might, and very soon this Merciless Knight will be no more.
The Ruthless Knight will give you the Yellow Diamond and you will be rewarded with eight spinels for your trouble once you return the request to the Merchant!
