Summary: While FromSoftware's massive Patch 1.17 update highlighted sweeping weapon adjustments and competitive PvP rebalancing, it appears the developers hid an unlisted narrative surprise for hardcore lore hunters.
According to breakthrough data-mining logs shared across Reddit and Discord overnight, the update secretly implanted two highly challenging hidden NPC Red Phantom Invasions located within the rot-infested expanses of Caelid and the pristine architecture of the Royal Capital of Leyndell.
Defeating these phantom invaders rewards players with completely unique, never-before-seen weapons that cannot be obtained through standard progression. If you are tracking down every piece of gear in the new patch, follow this comprehensive walkthrough to trigger both encounters and optimize your character builds.
Encounter 1: The Rotten Vanguard Invasion (Caelid)
This encounter is designed for mid-to-late game character builds and requires you to navigate the hazardous, Scarlet Rot-infested swamps of central Caelid.
Step-by-Step Trigger Guide
Travel to Caelid: Teleport to the Aeonia Swamp Shore Site of Grace.
Clear the World Conditions: Ensure that Commander O'Neil has been defeated in your current playthrough loop. If he is still alive, the code flags will not allow the phantom to materialize.
Navigate the Swamp: Ride Torrent toward the dead center of the swamp, precisely where the giant broken roots submerge into the boiling rot liquid.
Trigger the Forced Dismount: Your character will be forcefully dismounted from Torrent, signaling that your connection to the spectral steed has been severed by the arrival of "The Rotten Vanguard" phantom.
Deep Combat Strategy
The Threat: The invader wields a massive, scarlet rot-infused Greatsword with heavily delayed sweeping strikes that can easily catch players rolling prematurely. His heavy poise makes him difficult to stagger with light weapons.
The Counter: Keep your distance and utilize frostbite or lightning incantations to exploit his slow movement speed. Equipping the Flame, Cleanse Me incantation is highly recommended to mitigate the passive environmental rot buildup during the fight.
Exclusive Weapon Reward
Weapon Name: Vanguard's Decay Cleaver
Weapon Type: Strength-scaling Colossal Sword.
Unique Skill (Ash of War): Vanguard's Blight Strike - A heavy downward smash that triggers a localized cloud of intense scarlet rot build-up, lingering on the battlefield for 6 seconds and decimating enemy health pools in PvE environments.
For players optimizing their builds before taking on difficult encounters, managing Elden Ring Runes efficiently can help support the required character upgrades and equipment choices.
Encounter 2: The Ghost of the Crucible (Leyndell, Royal Capital)
This secondary invasion is a high-level encounter that dynamically changes its spawn location based on your primary world progression state, making it highly missable.
Step-by-Step Trigger Guide
Pre-Ashen Capital Phase: If Leyndell is not yet buried in ash, teleport to the Avenue Balcony Site of Grace. Head down the main staircase and turn directly into the abandoned chapel courtyard on the lower right flank.
Post-Ashen Capital Phase: If you have already burned the Erdtree and triggered the endgame world state, the invader can instead be located roaming the outer rim of the giant dragon statue's petrified wing.
Trigger the Spawn Requirement: Approach the stone altar inside the chapel (or the tip of the wing in the Ashen version) while holding at least 50,000 unspent Runes in your active inventory. This structural currency requirement acts as the primary code trigger to summon the aggressive phantom.
Deep Combat Strategy
The Threat: This invader behaves similarly to an elite Crucible Knight, utilizing hyper-aggressive shield-charges, high-tracking stabs, and holy tail incantations that punish players who attempt to heal at close range.
The Counter: Parrying is highly effective against his standard sword swings. Wait for his dual-handed overhead strike to open up critical riposte windows. Alternatively, high-stance break weapons like the Moonlight Greatsword can crack his guard after three consecutive heavy attacks.
Exclusive Shield Reward
Weapon Name: Crucible Echo Greatshield
Weapon Type: Strength/Faith-scaling Greatshield.
Passive Bonus: Holy Reflection - Features an integrated passive framework that automatically reflects 20% of incoming magical or holy damage back toward the attacker when performing a perfect guard, giving hybrid shield-builds immense defensive utility in PvP duels.
Players looking to complete these encounters and experiment with the newly uncovered rewards can also explore options to buy Elden Ring Items for different build setups.
Lore Analysis: Who Are These Phantoms?
Item descriptions extracted from the newly dropped loot suggest that these phantoms bridge gaps in Elden Ring's existing narrative:
The Rotten Vanguard: Lore text implies this knight was one of Malenia's original cleanrot commanders who succumbed entirely to the rot during the battle against Starscourge Radahn, left to wander the swamp as a mindless spirit.
The Ghost of the Crucible: This knight appears to be a discarded member of Godfrey's original crucible order who refused to bow to the Golden Order when Radagon ascended to Elden Lord, hiding within the Capital's shadows ever since
