How to Beat Commander O’Neil in Elden Ring

This Elden Ring boss is a melee fighter but that does not mean he will not attack you from a distance. His close-range attacks are really strong and you can take some massive damage from him. He will use swipe attacks mostly in horizontal directions. It will start from one side and end on the other and if he attacks you directly in a straight position, it will knock you out. Therefore, you will have to be careful when the commander uses this type of attack.

If you wind up behind Commander O’Neil he’ll occasionally poke you with the back of his halberd, stunning you so he can turn around and face you again. This attack is so fast that you probably won’t avoid it, but it’s also pretty weak.

If you think that you can go behind this humanoid and attack him from behind then you are wrong. Commander O’Neil will attack you with his halberd to stun you and then quickly turn around to attack you again. This is a very quick attack that is hard to avoid. But, do not worry as it does not deal massive damage.

Like we said in the beginning that Commander O’Neil will summon to aid him in the fight. You will first have to focus on these reinforcements and kill them as soon as possible because if you try to face both together, then it will be very difficult for you. Why focus on them? The Commander will buff them with his powers and this will be bad for you. Therefore, getting rid of them will help you to survive in this fight.

Important things to remember in this fight

Remember that Commander O’Neil’s attacks will have Scarlet Rot buildup and if you take damage by the status ailment’s full glory then this fight will end soon for you. We recommend you have a ranged strategy in this fight. 

Commander is a bit slow and his attacks are very easy to predict. Therefore, you can take this opportunity and attack him from a distance. Even if he tries to reach near you, just dodge or block his attacks. Not all of his attacks deal massive damage, so taking some hits is fine. Just keep in mind to drain his HP as quickly as possible.

Deal with the second wave of summoned reinforcements quickly. There will be soldiers with giant axes and they will all come together to attack you. Keep moving and try to kill all of them quickly. They should be your first priority because it will be difficult to face all of them and Commander O’Neil all at once. 

Things to keep in mind

  • Commander O’Neil is weak to Physical Thrust Damage, and Magic.
  • He summons players and spirit ash.
  • He will summon spirits and also buff them in the fight which will make them stronger.
  • Range strategy is the best against this optional Elden Ring boss.
  • Use torrent to move around the area as it will be very beneficial in this fight.
  • The Rot Tornado is the deadliest attack and deals massive damage.
