Elden Ring boss guide – How to beat Sir Gideon Ofnir, The All-Knowing

I’ll be frank: Sir Gideon Ofnir won’t be the toughest boss you’ve faced in Elden Ring. If you’ve managed to “do well” up to this point, he’s fairly easy. In fact, you should be able to finish this fight in one go, so long as you don’t get too cocky.

Elden Ring Sir Gideon Ofnir, The All-Knowing boss fight

Sir Gideon is a sorcerer of impressive quality, and is able to use many spells and incantations you’ve seen from bosses before. He typically starts off with using the Glintblade sorcery, while firing off Comets. Like fights against other Tarnished, Sir Gideon can heal himself with the Flask of Crimson Tears. However, I noticed he’ll only do it once.

  • Comet – Sir Gideon fires off a bolt of energy that tracks you.
  • Comet Azur – The big brother of comet is a beam of energy that deals a lot of damage at once.
  • Glintblade – Sir Gideon often starts out casting this sorcery, which fires off several blades made of magic. They will track you, but are easily dodged.
  • Law of Causality – A defensive incantation that looks like a golden ring on Sir Gideon’s torso. It will cause an explosion after about five hits.
  • Scarlet Aeonia – A move borrowed directly from Malenia, the Scarlet Aeonia lifts Sir Gideon into the air before sending him back to the ground, creating an orange flower that causes damage and scarlet rot buildup.
  • Bloodboon – A move borrowed from Mohg, Sir Gideon will reach up before sending a wave of burning blood your direction. It causes damage and bleed buildup.
  • Rykard’s Rancor – The boss who used this move is right in the name. Rykard’s Rancor sends out a slow-moving skull that tracks you, and after a few moments, explosions will follow along the trail it leaves behind.
  • Discus of Light – Sir Gideon flings out Krillin’s Kienzan, that is, a disc made of light that returns to its caster.

Sir Gideon Ofnir has a lot of spells, doesn’t he? But thankfully, most are easily dealt with. The Comet, Glintblade, and Comet Azur can be avoided with a dodge or just sprinting horizontally from their path. Law of Causality is a bit trickier to tackle, but in my experience you can attack through it. Just keep in mind how many times you’ve hit him. After three or four strikes, you can back off and wait for it to fade, or use that time for long-range attacks.

The most challenging attack is the Scarlet Aeonia, but avoiding it is roughly the same as before with Malenia. Wait until he begins to leave the air, and then dodge roll through the attack. Don’t get too close, or you can be afflicted by the rot. Simply wait it out, or attack from long range.

There are also stone pillars in the arena. You can use those to dodge his magic, which is helpful especially against Bloodboon. It’s a tactic I suggested before with the fight against Mohg, the Omen.

For the most part, however, Sir Gideon Ofnir, The All-Knowing should go down as one of the nicer boss fights in Elden Ring. Melee combat builds will do the best against him, as his poise is damn near nonexistent.
