Final Fantasy 16: Defeating the Muddy Murderer – A Full Guide

Few creatures stir as much dread in the hearts of Rosaria‘s warriors as the notorious Muddy Murderer. This vile being, also known as the Flan Prince, lurks inside a secluded valley along Hawk‘s Cry Cliff, ambushing any foolish enough to wander near. As a level 38 adversary, the Muddy Murderer dominates all who face him with an arsenal of deadly magics that spell certain doom.

But for those brave souls yearning to test their mettle against this magical terror, victory rests within grasp. I‘ve battled this flan monstrosity countless times across the scarred valley that it calls home. Hard-earned wisdom from these bloody encounters has shown me the way to defeating this magical fiend. Heed my guidance, stalwart warrior, and you too can emerge triumphant against this legendary foe!

The Legend of the Flan Prince

While little is known about the Muddy Murderer‘s origins, chilling tales paint him as an ancient flan warlord who once terrorized early Rosarian tribes. He dominated the land with powerful magics before finally being struck down by a legendary warrior. But the devious flan had sacrificed his mortal form to transfer his spirit into the earth itself.

Over long years, the residuals of the flan warlord‘s magic energies accumulated underground, coalescing back into physical form. Thus the "Flan Prince" was reborn into the world, this time as a hulking mass of sentient slime with a vengeful lust for destruction. He retreated to a secluded valley along Hawk‘s Cry Cliff to rebuild his power and plot his return.

Within the Valley of Peril

The Flan Prince makes his lair inside a wide valley basin along the southern reaches of Hawk‘s Cry Cliff. High stone walls surround the area, with only a few narrow passes permitting entry. Lush fauna carpets the valley floor, fed by a thin river that winds towards its center.

The area would seem peaceful, if not for the dread inspired by its vile inhabitant. Enter the valley grounds with caution, warriors, for the Flan Prince lurks unseen, awaiting fresh victims. Patrols sent to investigate disappearances report violent quakes emanating within, hinting at fierce battles happening beyond sight. And not all who venture in come back out…

Entering the Valley

To find the passage into the valley of the Flan Prince, head east from Auldhyl Dock through the cliffsides until you reach a descending gorge. Follow this ravine as it winds north, opening up into the secluded basin beyond. Use your Hunt Board for directions if lost.

Note the sparse vegetation and eroded walls – signs of the Flan Prince‘s destructive magics. The narrow entrance ensures that you must pass by the beast‘s domain at the valley‘s center. Tread lightly, warrior…

The Flan Prince‘s Formidable Powers

Lurking somewhere within this valley basin is the dreaded Muddy Murderer himself. Few have faced the Flan Prince and survived to tell of it. But their scattered accounts describe a hulking mass of ooze, muddy brown in color, with two thick arms ending in curved bone-like claws.

The Prince‘s body quakes with surging elemental energies from within. His mastery over the magical arts is profound, honed over centuries of manipulating the valley‘s ley lines. Do not underestimate this foe…

Terrifying Magical Abilities

The Flan Prince wields a spectrum of deadly spells to annihilate enemies. His most common attacks are:

Aeroga – whips up slicing wind funnels across a 50-ft radius. Each deals 650+ wind damage.
Stonega – bombards areas with boulders dealing 800+ earth damage each.

Blizzaga – fires ice shards that spread, dealing 700+ ice damage.

The wide affected spaces and high damage of these spells make them difficult to endure. Getting caught within almost assures a brutal demise.

Giant Monstrosity

In addition, the Flan Prince uses his massive frame to deliver crushing force, by:

Tornado Spin – flails towards you while spinning at high speeds.
Body Slam – spikes self into the ground, blasting rocks up that deal 850 damage.

Pound – smashes area with fists dealing 600+ damage.

These physical blows deal heavy damage themselves. And the Prince may use basic melee attacks between spell casts to chip away at your health.

Gear and Builds Tailored to Slay Royalty

Now that you know the Flan Prince‘s deadly capabilities, properly outfitting Clive can tilt the scales toward victory. As a level 38 adversary, your equipment should meet or exceed that in quality.

Weapons & Armor

Prioritize gear with magic resistance, as the boss relies heavily on spells. Ideal pieces include:

Armor – Lord‘s Plate+ (heavy armor, high dark resist)
Head – Magus Hat+ (magic evasion, MP regen)
Accessory – Echo Ring (magic barrier), Soul Ring (dark absorb)

Upgraded weapons with lightning/earth bonuses work well too, like:

Swords – Stormbrand (lightning), Gaia Blade (earth)


Lord‘s Plate+ – 825 Armor, +38 Dark Resist

Magus Hat+ – 402 Armor, +25% Magic Evade, +5 MP/sec
Echo Ring – Absorbs 1 magical hit

Soul Ring – Absorbs Dark Elemental Damage

Curatives, Items & Buffs

Keep ample restoratives and remedies on hand, like:

Healing – 10x Hi-Potions, 5x X-Potions, 2x Elixirs

Cures – 5x Remedies (for spell side effects)
Buffs – Magi-Spheres, FaithSpheres (magic boosting)

Phoenix Downs and Echo Herbs to revive fallen allies are also essential must-haves!

Abilities & Combos

Useful combat abilities against the Flan Prince include:

Rift Slip – cancels spells/abilities mid-cast.
Ignition – fire shield used when charging through spells.

Blind Justice – lightning orbs that attach and explode.

Combine with Thunderstorm sword art for max damage:

  1. Bait Aeroga vortexes.
  2. Trigger Blind Justice underboss.
  3. Use Ignition and rush boss with Thunderstorm!

Strategies for Slaying Slime Royalty

Now comes the true test – facing down the terrible Flan Prince himself. Move with vigilance through the valley grounds until you trigger his appearance. Then the real battle begins!

Evade and Retaliate

Focus on dodging the Prince‘s wide-reaching spells, then counterattack when he‘s vulnerable. Bait out his bigger abilities that leave him tired afterward.

Burst Damage Windows

Use hit-and-run tactics – engage for quick damaging ability bursts, then retreat out of range before he can respond.

Heal Frequently

If you take any hits, heal immediately. The boss deals too much damage to survive while injured.

Exploit Weaknesses

Target the Flan Prince‘s weaknesses to lightning and swords for bonus damage whenever possible!


Key Tips:
● Telegraphs long cast times for big spells – evade them!

● Weak after missing abilities – exploit those windows!
● If MP low, he‘ll focus melee attacks.
● At 50% HP, he may enrage for final stand!
