Dragonlord Placidusax is found in Crumbling Farum Azula, but not on the main path. You won't meet him just by playing normally.
To reach him, you must start from the Beside the Great Bridge Site of Grace. From there, you go down the elevator, exit the building, and carefully drop down onto a series of platforms below. At the very bottom, there is a quiet stone area with no bones on the ground. When you stand there, you will see a “Lie Down” prompt. Using it teleports you to Placidusax's arena .
This is why many players struggle to find him. The game gives no quest marker, no NPC hint, and no obvious path.

Placidusax is 100% optional. You do not need to defeat him to finish the story or reach any ending. That said, he is still considered a major late-game boss because of his difficulty, rewards, and lore importance .
Most players miss Placidusax because:
If you don't see the prompt, you are probably standing slightly off position. Walk around slowly near the center of the stone platform until it appears.
Placidusax uses a mix of fire, lightning, and teleporting attacks. He is fast for his size and hits very hard.
Key things to know:
He is weaker to pierce damage, while most status effects work poorly on him .
The fight has a clear phase shift at around 50% HP.
Phase two looks chaotic, but the attacks follow set patterns. Staying calm matters more than raw damage here.
This fight rewards patience.
Helpful tips:
Spirit Ashes like Mimic Tear or Black Knife Tiche can help draw attention and give you breathing room.
Placidusax favors:
Very slow weapons can work, but only if you don't get greedy.
Here is what you get for winning:
| Boss | NG Runes | NG+1 Runes |
|---|---|---|
| Dragonlord Placidusax | 280,000 | 560,000 |
You also receive the Remembrance of the Dragonlord, which can be traded for powerful gear or consumed for more runes .
For players pushing late-game builds or NG+, this rune reward is significant. Some players even plan their leveling routes around bosses like this, and it's one reason why discussions about buy Elden Ring runes often come up when people want to save time and focus on builds instead of farming.
No known quests are locked or broken by killing Placidusax. You can fight him at your own pace without worrying about NPC progress.
Placidusax is believed to be an ancient Elden Lord, ruling long before Queen Marika and the Erdtree. He waits in a storm beyond time, abandoned by his god, frozen in a moment that never ends. His missing heads hint at an ancient war and a fall from power, making him one of the most tragic figures in Elden Ring lore .
Simply put, Elden Ring wants this fight to feel like a secret. No NPC tells you about him, and no map points the way. Finding Placidusax feels earned, which is exactly why so many players remember him long after the fight is over.
Dragonlord Placidusax is a hidden, optional boss in Crumbling Farum Azula with a challenging two-phase fight, massive lightning and fire attacks, and strong rune rewards. He is not required to finish the game, but he offers deep lore, a memorable battle, and a big payoff for players willing to explore carefully and fight smart.
