How to defeat Sir Gideon Ofnir in Elden Ring

sportskeeda.com:

For most players, one of the final fights in Elden Ring will be Sir Gideon Ofnir, the All-Knowing, as the game nears its closing battle. What separates this boss from many of the others is that players had known Sir Gideon since the beginning of the game when the Roundtable Hold was first introduced.

This fight must be completed if players wish to move ahead in the game, and it is one of the three final fights that take place in the Ashen Capital of Leyndell. This duel of Roundtable members is available after taking down Maliketh the Black Blade within Farum Azula.

Depending on who players have encountered, Sir Gideon Ofnir seems to learn abilities based on word of mouth. This means that if players defeat Malenia or Rykard, then Sir Gideon will be able to use some of their abilities in the final fight. This process may occur when he asks for information on the found demi-gods within Elden Ring, and it certainly affects the main fight itself.

Tips for fighting Sir Gideon Ofnir:

Aside from being a fight with a lot of familiar moves for the player, there is also plenty of story significance to the encounter.

From the start, Sir Gideon made it somewhat clear that he also has ambitions of becoming an Elden Lord. He also seems to have secrets about Marika that he does not wish to divulge and would protect.

Ultimately, he doesn't believe another Tarnished can take down a god, despite the goal that was set in the beginning. This battle is his way of stopping the process and taking down the Tarnished before the main battle in Elden Ring.
