Elden Ring has many characters players can complete quests for and summon for assistance in a boss fight or two. However, there are some characters that players may not know they can summon for help, but should definitely try to. Some of these characters may only be encountered through their summon sign, while others have long questlines.
NPC summons is a common feature of Soulsborne games. Many times, these NPCs can be encountered in certain locations and will only move when the player has progressed to a new area. Other times, these NPCs will tell the player they are looking for something or someone, and the player can assist the NPCs. Moving these NPCs along and helping them may be essential to their questline, which many players may want to complete. There is also a chance that players can accidentally kill an Elden Ring NPC.
Elden Ring has several NPCs that can only be summoned when certain steps are taken. Players going through their first few playthroughs of Elden Ring may miss these important steps and not have the chance to summon a certain NPC. Other NPCs can only be summoned when specific choices are made that will drastically alter the game’s storyline.
Elden Ring's Coolest Summons - Shabriri Of The Frenzied Flame
Shabriri in Elden Ring is best known for his affiliation with the Three Fingers. He can be encountered near the Zamor Ruin and has taken control of Yura’s body. Shabriri claims Yura died and gave him his body. When spoken to Shabriri will tell the player to seek out the Three Fingers in the Cathedral of the Forsaken, below the Subterranean Shunning-Grounds.
If players do as they ask and embrace the Frenzied Flame, they will be able to summon Shabriri for Elden Ring's Godfrey, First Elden Lord boss fight. Keep in mind that meeting the Three Fingers will lock the player out of the other ending choices unless they have Miquella’s Needle. With this Needle, players can undo their actions in 
Dragonlord Placidusaxarena.
Elden Ring Summons - Old Knight Istvan
Old Knight Istvan is a summonable NPC for the Demi-Human duo boss fight in the Coastal Cave. While not much is known about Istvan in Elden Ring, the information available to players is he is one of the oldest Tarnished around. As helpful as he is, some players may recognize his name because he is one of the Volcano Manor’s targets.
The Loathsome Dung Eater Can Be Summoned In Elden Ring
The Dung Eater is a terrifying Elden Ring NPC. He can first be encountered in the Roundtable Hold, and then later in the Subterranean Shunning-Ground. If players complete their quest, the Dung Eater will reward them with the Mending Rune of the Fell Curse. This rune can be used to unlock one of the game’s five endings.
During his questline, the Dung Eater will be an invader at certain points, but he can also be an NPC summon for two different boss fights. After releasing the Dung Eater from his cell in the Shunning-Grounds, players can find his summon sign outside Mohg, the Omen’s boss room. His summon sign can also appear when the player faces Morgott, the Omen King in Leynedell, Royal Capital.
Elden Ring's Tragic Sorceress Sellen Can Be Summoned As An NPC
Elden Ring's Sorceress Sellen is an NPC character whom players can meet early in the game. She is located beneath the Waypoint Ruins; to reach her players must defeat the Mad Pumpkin Head boss. For some players, Sorceress Sellen may be a crucial NPC because she sells sorceries and will take found sorcery scrolls.
Sellen is best known for being the player’s teacher and friend that has an incredibly unsettling end. But she can also be an NPC summon for the Red Wolf of Radagon boss fight in Raya Lucaria Academy. To find Sellen’s summon sign, players must progress her storyline to the point that she heads to Raya Lucaria Academy.
Elden Ring Summons - Polyanna, Adopted Daughter
Polyanna, Adopted Daughter is a summonable NPC for Elden Ring’s optional boss Commander O’Neil located in the Swamp of Aeonia. Players may notice that Polyanna shares some resemblance with Millicent; this is not a coincidence because they are sisters. Polyanna is even present at the end of Millicent’s questline. To summon Polyanna for the Commander O’Neil encounter, players must first talk to Gowry at his shack outside of Selia, Town of Sorcery.
Key Elden Ring NPC Millicent Can Be Summoned
Millicent is an important NPC with some form of relation to Malenia. She has one of the longest NPC questlines in the game, and she appears as a summon for several boss fights. However, if players do not do her quest in the correct order, her may summon sign may not appear for these bosses.
The first boss she can be summoned for Elden Ring Magma Wyrm Makar in the Ruin-Strewn Precipice. For her summon sign to appear, players must give the Unalloyed Gold Needle to Gowry, who will repair it. When it is repaired, take the repaired needle to Millicent who will use it on herself. After resting and exhausting her dialogue, she will move to Gowry’s shack. After speaking to her again, players should be able to summon her for the Magma Wyrm Makar's fight.
The next boss fight she appears at is the Godskin Apostle at the Dominula, Windmill Village, but there must be some steps taken before she is available. Millicent can be found next to a cliff near the Erdtree-Gazing Hill site of grace. After talking to her, players can head to the Shaded Castle and search for the Valkyrie Prosthesis for Elden Ring's Millicent. Return to Millicent, who is still near the site of grace, and give her the prosthesis. She is now available for the Godskin Apostle fight.
The third boss she can be summoned for is the Draconic Tree Sentinel. For this sign to appear, all players need to have done is give her the Valkyrie Prosthesis and have defeated the Godskin Apostle. The final Elden Ring boss she can summon is the Black Blade Kindred boss in the Forbidden Lands. Like the previous boss, players just need to have given Millicent the prosthesis and defeated the Godskin Apostle.
