Demon's Souls NPC Quest Guide: Who to Save and Kill

The NPC quests that matter most in Demon's Souls are the three teacher rescues (Sage Freke, Saint Urbain and Yuria the Witch), Ostrava's four-part story in Boletaria, Biorr's rescue before the Penetrator, and the Patches, Yurt and Mephistopheles chain that decides who survives in the Nexus. The short version: rescue Ostrava every time he appears, leave Patches alive, and if you free Yurt, kill him at once. Below is each questline in the order you will meet it, with what you gain and what you can lose.

We checked every step against the Fextralife Demon's Souls wiki's NPC pages (Ostrava, Yuria, Freke, Urbain, Biorr, Patches, Yurt, Mephistopheles, Blige, Satsuki and Sparkly the Crow) and PowerPyx's spell and trophy guides in November 2026. Spoiler warning: this guide describes how several characters' stories end.

Rescue the Three Teachers First

Three NPCs turn the Nexus into a magic school, and all three need rescuing. They are the reason a caster or Faith build feels so different from a pure melee run, so get them early.

Sage Freke, the Visionary is locked in a cell in the Prison of Hope (3-1). The Special Key hangs on the wall near the top of the tower, before the Fool's Idol, behind the Dregling you have to kill to stop the boss from reviving. Unlock his cell, talk to him, and he moves to the Nexus. He teaches 15 spells, but only if you have at least 10 Magic. His apprentice handles the cheap basics such as Soul Arrow, Flame Toss and Water Veil.

Saint Urbain is trapped in a chamber in the Ritual Path (4-2). Patches leads you to the hole Urbain is stuck in, but if Patches is already dead, Urbain is still at the bottom and you can simply drop down. Once in the Nexus, Urbain teaches all twelve miracles, and he needs you to have 10 Faith before he will teach anything.

Yuria the Witch is held at the top of a tower in the Inner Ward (1-3), guarded by a Fat Official. The remake changed her rescue: you now need to wear the full Fat Official set (the Official's Cap, Gloves, Clothes and Leggings) as a disguise before the staircase lowers. Defeat the Fat Official at the top, take the disguise off and talk to her. She teaches six spells, each paid with a Demon Soul, and unlike Freke she has no Magic requirement. What each teacher sells is covered in our guide to the best spells and miracles.

Ostrava of Boletaria, Step by Step

Ostrava is the earnest young knight you keep pulling out of trouble in the Boletarian Palace. His quest runs through all four Boletaria sections, and each rescue pays something.

1. Gates of Boletaria (1-1): he is surrounded by Dreglings. Save him for a Brass Telescope.
2. The Lord's Path (1-2): he is trapped at the end of the lower hallway by crossbow soldiers. Save him for 3 Dark Moon Grass.
3. Inner Ward (1-3): he is fighting two Red Eye Knights near the large gate. Kill them fast and he gives you a Pure Clearstone, which the wiki calls the surest way to get that stone.
4. The King's Tower (1-4): he waits at the base of the steps and, if you saved him every time, hands over the Mausoleum Key, which opens the door behind the Red Eye Knight in the Gates of Boletaria.

His ending is sad either way. Later in 1-4, a Black Phantom Ostrava guards the way to the False King and must be fought, and he drops the Rune Sword and Rune Shield. The wiki warns he can be knocked off the narrow bridge, losing the drop, so lead him down the stairs. If he dies early in Boletaria and you miss the key he drops, it is gone for that playthrough. Keep the Brass Telescope in mind too: Sparkly the Crow trades the Fragrant Ring for it.

Biorr of the Twin Fangs

Biorr is the legendary knight locked in the palace dungeon, and freeing him gives you an ally in two fights.

You can only start once the Inner Ward is open, which requires clearing another world first. The first Fat Official in 1-3 drops the Iron Key Ring, and that key opens a dungeon door near the Tower Knight's end of the Lord's Path. Biorr's cell is inside. A third Fat Official down there drops the Bloody Iron Key, part of the original route to Yuria.

Once free, Biorr joins you for the Penetrator, announcing himself with "Do you need some help?" Beating the Penetrator with him earns the Brother-in-Arms trophy. If he survives that, he helps again in the King's Tower by keeping the Blue Dragon busy until he dies. He offers no reward for the rescue, joking that he has none to give, but his help is worth more than an item.

Patches the Hyena: Kill Him or Not?

Patches is a con man. In Stonefang Tunnel he offers you treasure as a gift, and taking it sets loose a swarm of Bearbugs. In the Shrine of Storms he urges you to peer into a pit of treasure he cannot reach, then mocks you as you fall. It is very tempting to kill him for revenge.

Do not. The wiki strongly advises leaving him alive, because he then settles in the Nexus beside the Tower of Latria Archstone as a merchant. His stock is genuinely useful: he is the only merchant with an unlimited supply of Heavy Arrows, he sells rings such as the Cat Ring for 40,000 souls and the Fragrant Ring for 60,000, and his stock grows as you kill more Archdemons. He also points you to Saint Urbain. Killing him is optional; he drops the Thief Ring, and Mephistopheles will pay you for it, but you lose a shop for the rest of the playthrough.

One quirk: if you met him in the Tunnel City, killing the Adjudicator can make him leave the Nexus until you find him again in the Ritual Path. If he goes missing, look for him at his spot in the other world.

Yurt and Mephistopheles: The Dark Path

Yurt, the Silent Chief, is caged in Upper Latria (3-2), and freeing him is a trap for the unprepared. If you leave him alone after releasing him, he kills named NPCs in the Nexus in a set order: Freke's Apprentice, the Acolyte of God, Patches, Saint Urbain, Sage Freke and finally Yuria. They do not come back until New Game+. The wiki's advice is blunt: kill him immediately. He tolerates up to three backstabs before turning hostile, and he drops the Gloom set and 780 souls.

Killing Yurt is also step one toward Mephistopheles, the assassin who appears on the Nexus's upper floor once you have killed Yurt and reached Pure Black character tendency. She hands out contracts in order, and each kill pays a reward:

• Saint Urbain and his followers: Stone of Ephemeral Eyes
• Sage Freke and his apprentice: Stone of Ephemeral Eyes
• Patches: Colorless Demon Soul
• Biorr: Colorless Demon Soul
• Ostrava: Talisman of Beasts
• Yuria: Foe's Ring

If a target is already dead, she skips to the next and pays nothing for it, and you must report back after each kill. The Foe's Ring matters to completionists, since the King of Rings trophy needs every ring. Our trophy guide explains how to fit this dark path into a platinum run without losing the teachers you still need.

Smaller Stories Worth Knowing

• Graverobber Blige: jailed in Island's Edge (4-1). The Copper Key frees him, and he then sells arrows, basic gear, Cloudstone Shards and Moonshadestone Shards, and warns you about Patches.
• Satsuki: found in front of the Shrine of Storms Archstone in Pure White world tendency, he wants the sword Makoto. Showing it to him just starts a fight, and the wiki says the questline gives no reward beyond that, but delivering Makoto counts toward the Worthy of the Sword trophy.
• Sparkly the Crow: nests at the highest point of Island's Edge. Drop one item near her tree, and if she likes it, reload or leave the world and return to find her gift. Each item can be traded once per cycle.
• Garl Vinland and Maiden Astraea: in the Rotting Haven (5-3), killing Garl first leads Astraea to take her own life, while killing Astraea first leaves Garl passive. The May you be unharmed trophy wants Astraea defeated without killing Garl.

Several of these characters also drop full armor sets when they die, including Brushwood (Biorr), Gloom (Yurt) and Dark Silver (Garl); our armor sets guide shows which of those are worth the cost. For when each NPC appears along the main route, see our area order guide.

Keeping Every NPC and Still Having Everything

Juggling these questlines means some items can only come from an NPC's death. If you would rather keep everyone alive and still have the gear, the store's Demon's Souls Mega Mule Starter Save comes stocked with all rings, all spells, most weapons, most armor, all arrow and bolt types, 99 of every consumable and material, and 10 million souls. Option 1 is a Soul Level 712 character with Phalanx defeated; Option 2 is a Soul Level 1 character at the very start with no bosses killed.

It is PS5 only, you choose one option before checkout, and you must already own Demon's Souls on PS5 because only the modded save is sold. See everything else for the game on the store's Demon's Souls page.
