FF Resonance Boss List: All 75 Story and Optional Bosses

Chapter 1

Boss	Lv.	HP	Weak to	Where	Tips
Belmodar	4	2,000		Earth Shrine	Have Rain cast Fire every turn to drain its stagger gauge. If you picked up a Flame Scroll I in the shrine, Lasswell can use it to add stagger too.
Hell's Rider	6	4,000		Grandshelt, the Royal Capital	Light and Ice both work, and your starting pair has access to each. Tronn's Hibernal Fury Resonance hits its Ice weakness several times. Fire off Limit Bursts from Rain and Lasswell as soon as they are ready.
The Hunger	9	2,500		Kolobos Ruins	Phase one wants Ice and phase two wants Light, so do not spend everything early. Stagger the first form before it dies to start phase two with free turns. In phase two, drop the two soldiers before focusing the boss.
Siren	11	20,000		Siren's Tower	Monk's Prayer Beads on Rain and Fina stop her Charm. Break her with Thunder from Cloud and WoL, then finish with Cloud's Ascension. Keep Fina healing and buffing while the other two deal damage.

Chapter 2

Boss	Lv.	HP	Weak to	Where	Tips
Liquid Thunder	13	10,000		Mt. Thunderclap	The Cape of the Raiju halves its Lightning damage. Earth skills from Lid and WoL hit its weakness. Defend on the turn after it charges up electricity.
Mom Bomb	14	21,000		Dwarven Forge	Cloud, Terra and Zidane all give Water attacks for its weakness. Summon Siren for extra Water damage. When the self-destruct warning shows, stun it or finish it fast.
Epimetheus	16	3,645		Mobliz Shipyard	This mini boss is weaker than most fights you have already won. Kill it quickly so its status ailments do not pile up. Save MP and items, since Adrastea comes right after with no break.
Adrastea	16	25,000		Mobliz Shipyard	Lightning and Water both hit its weak points. Cloud's Ascension Resonance does big damage here. Physical Counter on your party adds free damage.
Aether	18	34,000		Wind Shrine	Put Ice Visions like Tronn, Terra or Noctis on everyone but Lasswell. Tronn's Hibernal Fury is the strongest Ice option you have at this point. Kill each minion as soon as it appears so you do not get swarmed.

Chapter 3

Boss	Lv.	HP	Weak to	Where	Tips
Wave Lopros	20	21,000		Cave of Waters	Kill the Snappers first, before the boss eats them for a boost. Ice hits the boss, while Wind and Lightning handle the Snappers. Carbuncle helps soak its area attacks.
Water Dragon	21	24,000		Old Town, Olderion	Ramuh and Cloud bring strong Lightning damage. It acts twice a turn, so keep Fina healing and buffing between summons. Its attacks come in both physical and magic form, so raise both defenses.
Leviathan	23	40,000		Lake Dorr	Destroy the Orbs of Light first, since they keep Leviathan safe. Check each orb's weakness before attacking so no turn is wasted. Shellga or Carbuncle cuts its magic damage.
Alluvion	26	48,000		Water Shrine	Smash the Prism Cores with Lightning to weaken it. Cloud's Ascension Resonance makes short work of the cores. Tank with a high magic defense character wearing a Calm Armlet and Monk's Prayer Beads.

Chapter 4

Boss	Lv.	HP	Weak to	Where	Tips
Ignis	27	56,000		Weapons Factory	The first two meetings are scripted losses, so only the third counts. He is weak to Water, so give everyone a Water skill. Carbuncle reflects his Firagas, and a physical tank with Provoke draws his single hits.
Emperor of Zoldaad	30	52,000		Zoldaad Castle	Clear his soldiers before you focus on him. Carbuncle's Reflect bounces his status spells. Water skills on everyone speed things up.
Lazarov	30	45,000		Zoldaad Castle	He keeps adding test subjects with different weaknesses, so carry Wind, Water, Fire, Light and Earth. Finish off his experiments before turning on him. Carbuncle reflects his attack spells.

Chapter 5

Boss	Lv.	HP	Weak to	Where	Tips
Slagworm	33	90,000		Village of Sunioo	Give all four members Wind skills, since it can swallow one of them. Star Pendants block its Poison.
Iron Giant	34	85,000		Nameless Ruins	Leave physical attackers out, as its defense is very high. Lightning works, same as in the prologue. Raise physical defense or bring a Multi-Cover tank.
Liquid Flame	34	78,000		Nameless Ruins	Physical hits barely scratch it, so use magic. Ice and Water both work. Bring something to soften its Fire attacks.
Byblos	36	95,000		Arcane Library	Carbuncle reflects every spell it throws. Dark and Fire are its weaknesses. Be careful as its stagger gauge runs low.
Archwitch Fina	38	100,000		Fina's Psyche	Light and Water hit her weak spots. Her whip attacks add debuffs, so cleanse them often. At a quarter HP she takes far less damage and hits harder the next turn.
Tellus	39	135,000		Tower of Mysidia	Your first meeting stops by itself once a handful of turns pass, so just stay alive. For the real fight, carry Wind skills of both damage types. Raise defenses to absorb his area attacks.

Chapter 6

Archaeoaevis	40	130,000		Sanctissimus Shrine	Its weakness shifts, so bring every element. Strong non-elemental attacks ignore Barrier Shift entirely.
Dad Bomb	40	140,000		Sanctissimus Shrine	Reraise or WoL's Grit keeps you alive through its self-destruct. Or burst it down with Fire before it gets the chance to explode.
Test Rider	40	150,000		Sanctissimus Shrine	Use a physical tank to take hits for the party, and play safer while it is enraged. Earth and Light cover both of its weaknesses.
Yakhanati	40	145,000		Sanctissimus Shrine	Bring Dark and Wind attacks of both physical and magic types. Watch which damage type it is immune to at the moment.
Arch Gargoyle	40	55,000		Sanctissimus Shrine	Kill both gargoyles on the same turn, or the survivor revives its partner. Area Light or Wind attacks keep their HP even.
Dragon	42	175,000		Sanctissimus Shrine	Watch the countdown and shield the party when it is close to zero. Lightning brings it down fastest. Your Multi-Cover user holds up well with Clive at 3 stars or Mastery Rank 9.
Geldius	43	200,000		Sanctissimus Shrine	Fire takes him down quickly. Keep Protectga up so the whole party resists his physical hits.

Chapter 8

Chaotic Darkness (First Form)	55	180,000		Crystal Tower	Expect back to back fights, so do not empty your MP here. Take out the Left Hand with Wind and the Right Hand with Earth before the head. Buff the party and hit the main body with Light.
