1-method (Fair fight) for hardcore lovers Edit
-This method is included in learning the pattern of Eviterno's attacks, but unfortunately many are right that it is too obvious, I agree with you, the catch is that the boss is too fast, so many, even having studied his attack pattern, cannot defeat him.

If you are a hardcore fan and can pass without damage, then my only advice to you is to learn his attacks perfectly.

In addition, I'm sure you've seen videos on YouTube of the fight with Eviterna, many use time-stopping magic (like they're breaking the game), but this has already been fixed. Previously, this magic lasted 6.5 seconds, and now it lasts 3 seconds (I read it on Reddit). But in practice, I've also noticed this, it won't help.

Conclusion: Learn the boss's attack pattern and improve your reaction to perfection.

We all know Eviterno is too fast, so we will use his tactics against him. We need paired daggers (Sarmiento and Sentella) and statuettes to improve it.
In addition, pump it up to the maximum.

We must collect a combination of figurines for a dagger.
The list of figurines is as follows: Proximo, Veteran, Traitor, Maiden / Steadfast, Kaya, Gemino, Lebesha, Guardian.

There is one problem here, this is the statuette of the Unwavering, it can only be obtained by repairing the statuette of the Virgin three times at the Hollow Sinner (Man in Honey), that is, the Virgin turns into the Unwavering
If you do not know how to get the Unwavering, do not worry, here is a link to the instructions https://blasphemous.fandom.com/ru/wiki/%D0%A4%D0%B8%D0%B3%D1%83%D1%80%D0%BA%D0%B0:_%D0%94%D0%B5%D0%B2%D0%B0 click on it.
If your page opened in Russian, translate it into English.

IMPORTANT!! To break the statue of the maiden, simply equip it and kill enemies with it, the more enemies you kill, the faster you break it. AND BY THE WAY, AFTER SELECTING THE STATUETTE IN THE ALTAR, DON'T EVEN TRY TO KILL YOURSELF WITH IT, IT WON'T HELP, IT SHOULD HELP IN THE BATTLE.

Okay, we have a combination of statues and daggers, but what next? Then during phase 2
we will need to perform only one action, this is an endless roll attack with a dagger.

Let me explain why you need to attack continuously only with a roll, the thing is that Eviterno's fastest attacks require a roll to avoid them, and during that time you will be invulnerable. But in some places he can catch you and give damage, in this case, use health bottles if you have low HP, if your health is normal, continue the scheme.
I give you a 100% guarantee of a successful fight because I used this method myself and won it.
