If one keeps preventing him from entering phase 2, he would give up for a while and continue fighting. However if the attack landed too late and fire is already burning away on his sword, he would enter phase 2 anyway. While the Keeper attempts to do so, any attack will stagger him out of the animation, stopping him from entering phase 2.

When his HP is reduced to about two thirds, the Keeper will attempt to apply fire to his sword and gain new abilities.

Other weapons can still stun-lock, but his dodge attack would be fast enough to slip through between 2 swings of your weapon.

Do not completely deplete your stamina leave a little bit so you could dodge away at the end, or the Keeper will surely retaliate should you try to walk away.

Just keep on top of her, and when your stamina gets low hop back and recharge. The Keeper won't be able to attack or dodge away.

This boss can be easily stun-locked with the Blade of Mercy in dagger form.

It will often follow up its attack with a long reaching move and you will be caught with it if you're late. Continue the same tactic, however while compensating for its run speed, also immediately back dodge twice after landing your attack. After awhile, it'll apply Fire Paper to their blade and begin to run at you. Once it gets about 6 steps away, charge your Ludwig's Holy Blade power attack in Greatsword (transform) mode and let go just before it swings. To do this, get just in range of it so that it starts walking towards you.

The Keeper of the Old Lords can be beaten easily with Ludwig's Holy Blade by baiting her into engaging you, and staggering him in the middle of his somewhat slow attacks.

It's best to use the strategy outlined above for the first phase of the fight and then switch to poison daggers when it buffs its sword with fire.

If you're having trouble with this boss (like in a defiled dungeon where you only have half health, for instance), you can poison it with two Poison Knives.

Well timed blows can prevent the Keeper from completing any attack altogether.

Keeper of the Old Lords is staggered as easily as other human sized enemies, even when in the middle of an attack.
