How to prepare for Fallen Archbishop Andreus in Lies of P

To prepare for the fight against Fallen Archbishop Andreus in Lies of P, equip fire-based weapons and enhancements such as the Flame Grindstone or Fire Dagger, as Andreus is weak to fire damage. Bring thermites or fire canisters to apply additional fire damage during the battle. Master precise dodging and parrying, especially against his tongue attacks that inflict decay, and consider using a Specter companion to distract him. Keep your character’s weight below the overweight threshold to maintain stamina efficiency for blocking and dodging. Save special attacks for the later part of the fight to maximize damage. This preparation will help you handle both phases of this challenging two-stage boss encounter effectively.

You’ll fight Fallen Archbishop Andreus in St. Frangelico Cathedral, Lies of P’s fourth zone. As you proceed deeper into the labyrinthine sanctum, you’ll encounter several monsters and hazards that cause the Decay status effect, which serves as a precursor to what you can expect in the battle ahead.

How to manage the decay debuff

Similar to other status effects, Decay has its own gauge. Once the meter is filled, your character will suffer from an acid damage-over-time effect. Worse, your equipped weapons will also lose durability.

Since Fallen Archbishop Andreus has several attacks that cause Decay build-up, it’s imperative that you have items or perks that can either resist Acid damage or cure Decay, as well as those that can repair weapons. Here are some examples:

Consumable: Attribute Purification Ampoule. Completely cures the Decay status effect.
Converter: Corrosion Resistance. Provides resistance to acid damage.
P-Organ Minor perk: Enhance Attribute Resistance. Provides resistance to Decay, Overheat, Electric Shock, and Corruption build-up.
Venigni’s Urgent Repair Tool. Instantly repairs a weapon’s durability.

How to beat Fallen Archbishop Andreus boss fight phase 1

To beat Fallen Archbishop Andreus in phase 1, focus on dodging or parrying his claw swipe and strike attacks, as well as his tongue lash, which inflicts Decay and should be blocked rather than dodged. Stay just outside his attack range and dodge toward him just before his slams or sweeps to avoid damage and get in close for counterattacks. Use your Specter companion to bait attacks and target Andreus’s back for maximum damage. Parrying his claw combos can break his posture, allowing for a Death Blow. Be cautious of his body slam, which is unblockable and can be deadly if cornered. Using fire damage weapons like the Flamberge and consumables such as Thermite can help apply continuous damage and hinder his healing. Keep your distance when you see his infected wing appear, as he will unleash a decay-inflicting projectile wave that can be dodged by rolling through it. This approach will help you quickly deplete his health bar and preserve resources for the second phase.

Once you enter the Fallen Bishop Andreus boss chamber, a cutscene will play. This grotesque monstrosity will emerge from the ceiling, and you’ll have to fight him. Here are the abilities that you need to watch out for:

Tongue Lash: The creature strikes with his tongue twice in quick succession; both hits cause Decay.
Triple Swipe: The monster does three sweeping strikes with his outstretched hands.
Double Smash: When both arms are pointed upward, the boss will slam down on the ground.
Sitdown Squat: The boss will leap before squatting on the floor; this attack is unblockable.

Fallen Archbishop Andreus has slow and predictable attack patterns. Even better, you can dodge sideways to avoid his arm swipes, before following up with a couple of attacks with your weapon. The only problem here is the Tongue Lash ability. Make sure you block both hits. Otherwise, the Decay meter will likely get filled up.

How to beat Fallen Archbishop Andreus boss fight phase 2

In phase 2 of the Fallen Archbishop Andreus boss fight, focus on fighting from his backside, as this position allows you to avoid most of his attacks which are primarily directed forward or to the sides. The boss becomes two-headed, with the humanoid upper half wielding a staff and the original monstrous form attached behind it. The humanoid side uses staff attacks such as sweeping strikes, a staff slam causing a small shockwave, and a long-range stab, which can be dodged or parried with good timing. Watch for the glowing blue aura signaling an upcoming radial AoE attack and immediately put distance between you and the boss. Maintain mid-range distance to react to his combos, block or dodge his melee attacks, and reposition behind him to deal damage safely. Using a Specter companion can help distract the boss, giving you openings to attack. Patience, timing, and positioning are key to gradually depleting his health and overcoming the second phase.

After depleting the boss’ HP, another cutscene will play. The humanoid form of the archbishop will be revealed, and this will act as the creature’s tail of sorts. This leads to the second phase of the battle. Andreus will retain his previous abilities, and he’ll gain some new ones:

Five-Hit Swipe. The boss’ combo chain now hits up to five times. At certain points, its last strike will also be unblockable.
Rampage. The creature will rear and charge your location, while slashing multiple times. You can dodge sideways to avoid the initial lunge.
Walking Sitdown Squat. This is similar to Sitdown Squat, except the boss will move around before smashing its behind on the floor. This is somewhat erratic, and the boss could miss you completely.
Acid Breath. This is cast when the bishop (i.e. tail) is facing you. He’ll spew acid in a frontal cone, which causes Decay build-up.
Tail Swipe. The bishop’s tail will move sideways in a sweeping motion.
Tail Skewer. If the bishop’s tail does a wind-up move (i.e. akin to a scorpion about to strike), that means the tail will crash down on that spot, skewering you unless you move out of the way.
Ion Cannon. The monster (i.e. front) will charge a blue beam, firing a continuous stream in your direction.
Ion Skewer. This is similar to the Tail Skewer, except a beam will be fired instead.

This phase of the Lies of P Fallen Bishop Andreus boss fight is significantly more hectic due to you having to juggle two targets: the monster’s head and the bishop’s tail. They share the same health pool, but they tend to alternate periodically. Likewise, it’s possible to switch to another target by dodging sideways until you’re in front or behind the boss.

The goal here is to be mindful of which target is facing you. If it’s the large monster, then it’ll likely do the same attack patterns from the previous phase. However, if it’s the bishop’s tail, then it’ll have new abilities, including additional ones that also cause Decay build-up.

Moreover, make sure that your Grindstone is ready. Your weapon will have lost a lot of durability by now, so try to keep your distance whenever you need to repair. Alternatively, you can use a Venigni’s Urgent Repair Tool to instantly restore durability.

Fallen Archbishop Andreus boss fight rewards

After defeating Fallen Archbishop Andreus in Lies of P, players are rewarded with the Twisted Angel’s Ergo, a valuable item that can be exchanged with the NPC Alidoro for special rewards. One notable reward is the powerful weapon called the Trident of the Covenant, making the boss fight not only a challenging encounter but also a worthwhile one for obtaining rare and useful gear.

After defeating the boss, you’ll receive the Twisted Angel’s Ergo. This item can be exchanged with Alidoro to obtain either of these two rewards:

Weapon: Trident of the Covenant. This spear has Motivity C and Technique B scaling. Its blade skill does a frontal stab, followed by a downward crash. Its handle skill, meanwhile, executes a counterattack if you time it just as an enemy’s attack is about to land.
Amulet: Nameless One’s Amulet. Gives a slight chance not to consume Pulse Cells when you use one to heal.

What secret tactics can help me outsmart Fallen Archbishop Andreus

To outsmart Fallen Archbishop Andreus in Lies of P, use these secret tactics:

Apply Fire Abrasive or Thermite at the start of the fight to exploit his susceptibility to fire damage, setting him ablaze and weakening him over time.
Dodge through his attacks rather than relying solely on Perfect Guards; this prevents being pushed out of range and allows you to counterattack more effectively.
Watch for his tongue whip attack: dodge quickly twice to avoid both hits, then punish with attacks.
Stay mid-range to bait his big attacks like lunges or body slams, then close in immediately after to land combos or charged hits while he recovers.
Position yourself behind him when he lifts his body to perform a lunge or slam, as he cannot change direction then, giving you a safe window to strike.
Use a Specter companion to divide his attention, making it easier to attack from behind or the side.
Perfectly time dodges or guards against his double claw lunge and fury attacks for safer openings.
Equip weapons that inflict Overheat or Shock damage, such as the Flamberge or Fulminis, to stagger him and create critical attack opportunities.

These tactics combined will help you maintain control, minimize damage, and exploit Andreus’s attack patterns for a decisive victory.

What are the most effective ways to set Andreus ablaze early in the fight

The most effective ways to set Fallen Archbishop Andreus ablaze early in the fight are:

Use a Fire Abrasive or Flame Grindstone on your weapon before entering the arena. This fire enhancement allows your attacks to ignite Andreus after a few consistent hits, dealing extra damage over time.
Equip a weapon with inherent fire damage, such as the Salamander’s Dagger or the Flaming Legion Arm, to apply continuous fire damage and the Overheat status effect quickly.
Attack consistently between his parries and aggressive moves to build up the fire effect rapidly, which weakens him significantly during the fight’s initial phase.
Bring a Specter companion to distract Andreus, giving you more opportunities to land fire-enhanced hits without immediate retaliation.

These tactics combined help you exploit Andreus’s vulnerability to fire damage and gain an early advantage in the battle.
