The Dragonlord whose seat lies at the heart of the storm beyond time is said to have been Elden Lord in the age before the Erdtree. Once his god was fled, the lord continued to await its return.
The god of the dragons fled, leaving Placidusax a lord without a deity. The tattered and injured Placidusax would await the return of its god within the heart of the storm beyond time, deep within Crumbling Farum Azula. Here, Placidusax seemingly existed outside of time, eternally awaiting the return of the deity he had served.
Placidusax is a two phase boss fight in Elden Ring found in Crumbling Farum Azula. From the "Beside the Great Bridge" grace, turn around take the elevator back down into the church. Run past the gnolls and exit straight ahead out of the church, and look over the edge for a platform to fall down to. Follow the path to the end, and look for a cubby on the stone floor that doesn't have bones in it. Approach and look for the "Lay Down" prompt. You'll then be teleported to the boss arena.
There are two phases for Dragonlord Placidusax, the second starting at 50% hp. Placidusax has around 26000 HP in total (NG).
Placidusax has a large moveset, but is heavily limited in his options depending on your positioning.
The most dangerous place to be is at the dragon's sides, since both the fire breaths and wing-slams cover a large area next to him and hit twice for enough damage to oneshot you if you can't avoid the second hit.
Being in front of Placidusax means having to deal with claw attacks and the occasional fire breath, but the claw attacks can be avoided and the fire breath almost always comes as a followup to a claw attack while in front of him. The dragon also has regular two-hit combo claw attacks, so you should generally back away from him after dodging a claw.
Attacking Placidusax's tail is the safest option, but you still have to pay attention to the heads, since they can breathe fire backwards and still hit you while attacking the tail.
When Placidusax roars, he summons three consecutive red lightning strikes. You can avoid these by running and, depending on your weapon speed, stop to attack in between the lightnings.
Placidusax may do a supernova-type attack in which he slams a lightning spear into the ground. There will be a red pulse effect covering the area around him, serving as an indicator for how large the following explosion is going to be. You should always start to run away from him when you see him do this.
Placidusax can be staggered, allowing you to land a critical attack on one of the heads.
Phase two begins once Placidusax drops to ~50% HP. He will hover up into the air and disappear, then reemerge from a red cloud and plummet towards you. After stopping, he will sometimes vanish again and repeatedly teleport around to attack with his claws. The grounded teleports do not break lock-on, which makes avoiding the attacks relatively easy.
At ~25% HP, Placidusax will roar and disappear again without flying up. He will emerge from a cloud and crashland as usual, but this time starts to charge up a laser beam with both heads, sweeping over the arena multiple times. To avoid getting hit by this, run away from him as soon as he lands. If you get far enough away, you will only have to dodge one of the laser sweeps.
