In order to complete the Elden Ring, you have to fight the main story bosses in the game. Sir Gideon Ofnir, The All-Knowing is an NPC who is used to be in the Roundtable Hold. He would give you information about the Shardbearers. But when you kill Maliketh, the Black Blade, and set the Erdtree on fire he will move to Erdtree Sanctuary in Leyndell. Sir Gideon Ofnir, The All-Knowing has come to stop you from getting the Elden Ring. He is one of the main story bosses so, you have to defeat him.
In this guide, I will tell you how to kill Sir Gideon the fastest way possible.
For preparation, you need to have an Incantation named Inescapable Frenzy. You can find this incantation underneath the Endel in the subterranean Shunning-Grounds after killing the mog the omen.
From the Cathedral of the Forsaken Site of Grace, there’ll be a chest in front and you’ll find Erdtree Favor +1 Talisman inside it, after that hit the Altar behind it, and the secret passage will open.
As you go down and follow the path there’ll be a drop-down area with stone stairs, carefully make your way down and you’ll find the Inescapable Frenzy incantation on a stone stair down below.
As it spread madness to the enemies so it’s very useful in the fight with enemies who have the weakness of madness. It needs 21 Faith to cast and it costs 32 FP.
Defeat Sir Gideon Ofnir, The All-Knowing
After you have defeated Maliketh, the Black Blade you will be brought back to Leyndell and from where you spawn there’ll be grace in front. Just rest at the grace and go straight and then to the right to the stairs going into the doorway and there’ll be a lift inside. Take the lift and you’ll reach the boss fight place.
Now as you go through the gate for the fight, he will be giving a speech to you of some sort. Don’t listen to anything just go straight to him and use the Incantation, it will melt him like he is nothing, and in just 1 use of incantation, he is dead while he is still giving the speech. It is because Sir Gideon has a weakness of Madness and this incantation does a great amount of damage to those with the madness weakness.
Before attempting the use of incantation make sure you have equipped the most powerful weapon in your right hand from your inventory as it does more damage to enemies due to wielding an upgraded weapon in the right hand.
You will get All-Knowing Helm, Armor, Gauntlets, and Greaves. You’ll get the Scepter of the All-Knowing. You’ll also get 180,000 Runes.
