In Final Fantasy Resonance on PC, Aether is the Chapter 2 (“Eternal Blue”) encounter at the Wind Shrine summit on Dirnado, the Continent of Wind. His heavy hits and summoned allies make him dangerous, and one move can take out an underleveled party in one round. The figures here are from three Normal attempts, all of which ended in defeat; the battle was eventually cleared on Casual. Rain and Lasswell were Lv 18, Lid was Lv 16, and Fina was also in the party. Their max HP was 1,292 (Rain), 1,126 (Lasswell), 823 (Fina) and 810 (Lid).
Quick answer: A red marker on Aether’s turn-order icon means Heavenly Wind hits the whole party next round. Spend that round on Shellga, a full heal and Defend, and hit him with Ice the rest of the time.
Aether has 34,000 HP and is Lv 18. Ice is his weakness; Wind attacks have no effect. On Normal, Shell-style magic defense lowered Heavenly Wind’s damage by roughly a quarter to a third, but Protectga made no difference. Lid’s maximum HP is 810, and every Heavenly Wind took her out except for one cast while Shellga was active. Raise her level or keep Shell on her.
| Stat | Aether | Aether’s Minion |
|---|---|---|
| Lv | 18 | 18 |
| HP | 34,000 | 2,750 |
| Weak to | Ice | Ice |
| Resists / nullifies | Nullifies Wind | Halves Wind |
| Immune to | Poison, Sleep, Confuse, Petrify, Charm, Berserk, Instant Death, Gravity | Petrify, Charm, Instant Death |
| EXP / Gil | 2,700 / 4,500 | 102 / 80 |
| Drops | Sylph’s Tiara | – |
Blind, Silence and Paralysis rarely land on Aether. Sylph’s Tiara reads “Imbues non-elemental physical attacks with Wind.” Aether is a Humanoid boss with the trait “Summons minions.” You cannot escape the fight.
Before the fight: save, rest and prepare
The boss save point sits at the end of the Wind Shrine’s top-floor corridor (the route is in the Wind Shrine walkthrough). The first time you touch it, the game tells you “You can now return to the save point at the entrance.” Its menu offers Save progress, Rest in a tent and Teleport. Rest in a tent asks “Use item? Tent” with your Held and Use counts and a Yes/No choice, with the cursor starting on No. Confirming fully restores HP and MP.
Save here, then take the last lift up. Pack for a long fight:
- Ethers, because MP runs out first. Lasswell was down to 26 MP after about 12 rounds.
- Phoenix Downs. Two per attempt were used, mostly on Lid.
- Mist Potions or a Mist Hi-Potion (“Restores 800 HP for all allies.”).
- Tents for the save point.
The item shop in the Dwarven Forge stocks everything you need.
| Item | Price (Gil) |
|---|---|
| Ether | 500 |
| Mist Ether | 2,500 |
| Phoenix Down | 200 |
| Mist Potion | 500 |
| Tent | 300 |
The Wind Shrine’s door says Recommended Level 18, and a party at that level (Lid at Lv 16) lost three times on Normal. Go in a few levels higher, with Lid well above 810 max HP, and put the best armor from the Dwarven Forge armor shop on everyone. Equip the Leah Vision on Lasswell for Shellga and Cura, and keep Fina’s Light Veil available. In the losing runs, Lasswell carried Leah (Shellga, Cura, Shell), Rain had Tronn, and Lid had Warrior of Light (Protectga, Cura).
The cutscene and Aether’s stats
The lift brings you to the Wind Crystal. Lid exclaims “There it is! The Wind Crystal!”, Rain says “So you’re Aether…”, and Aether responds, “You have ignored my warning. And so, your chance for mercy is gone.” He then says, “I will eliminate you and destroy the Crystal…all so that the Invincible may fly again.”
Aether attacks first when the battle starts, and his opener hits one character for about 300-620. Unit Info shows “Aether Lv.18” with Affinities listed as “? ?” until you hit him with an element. Once Ice lands, the target displays “Weak” and “+200%”.
The Blizzara user makes a difference: Lasswell’s cast from Leah’s Skills (15 MP) dealt 387-409 damage, compared with 182-186 from Rain’s Blizzara in Tronn’s Skills. Selecting Q (All) for Blizzara divides the attack between Aether and the minion, dealing 160 and 179. Fina’s Siren Esper uses Wind, so don’t use it here.
Aether’s Minion
At the start of its turn in round 2, Aether displays the banner “Aether summons a minion!” The summoned minion is Lv 18, has 2,750 HP, and shares Aether’s Ice weakness.
Gravity halves the target’s current HP: Lasswell lost 563, while Rain went from 1,273 to 646.
Drain dealt 310 damage to Lid, and Aerora dealt 207 to Lasswell. During a Normal attempt, the minion remained alive with roughly one-quarter of its HP after 12 rounds. Use spare turns to take it out; Gravity landing just before Heavenly Wind can be fatal.
Aether’s attacks and damage on Normal
Aether mixes single-target hits with party-wide magic. Sonic Boom is a single-target hit; it did 216 to Lid.
Aerora hits all four characters, for 275-413 each.
Stab is another single-target hit, anywhere from 190 to 623 on Normal; it did 308 to Fina.
| Attack | Targets | Damage taken on Normal |
|---|---|---|
| Sonic Boom | One | 216 |
| Aerora | All | 275-413 each |
| Stab | One | 190-623 |
| Heavenly Wind | All | 307-1,009 each |
| Minion: Gravity | One | Half current HP |
| Minion: Drain | One | 310 |
| Minion: Aerora | One | 207 |
Heavenly Wind and the red marker
One round before every Heavenly Wind, Aether’s icon on the turn-order bar at the top of the screen gets a red marker with a yellow “!”. It came about every 3-4 rounds, landing in rounds 3, 7 and around 10 in one Normal attempt.
The next round opens with the “Heavenly Wind” banner, and the attack hits the whole party.
Damage per character is listed as Rain / Lasswell / Fina / Lid, all on Normal.
| Cast | Party buffs | Rain / Lasswell / Fina / Lid |
|---|---|---|
| No buffs, all at full HP, nobody defending | None | 941 / 749 / 629 / KO (810 max HP) |
| Protectga up, Lasswell defending | Protectga | 915 / 371 (defending) / 675 / 972, KO |
| Light Veil up, Rain and Lasswell defending | Light Veil | 470 (defending) / 359 (defending) / 623 / 1,009, KO |
| Shellga up, Rain defending | Shellga | 307 (defending) / 511 / 444 / 655, survived at 155 |
| Shellga up again four rounds later, nobody defending | Shellga | 660 / 547 / 470 / 943, KO |
Protectga (“Increase physical defense of all allies”) changed nothing, which makes Heavenly Wind magic damage.
Shellga is in Leah’s Skills: “[White Magic] Increase magic defense of all allies”, 25 MP.

Cast before the first Heavenly Wind, Shellga cut the damage by roughly a quarter to a third, and Lid survived at 155 HP.
The second cast under Shellga still killed Lid, so Heavenly Wind seems to hit harder later in the fight. Defend roughly halves the damage for whoever uses it. For how these effects stack, see buffs and debuffs in Final Fantasy Resonance.
Failing to prepare for the attack can be disastrous: one Heavenly Wind took out Rain, Lasswell and Lid, leaving Fina with 96 HP and the message “Fina is asleep!” on screen.
What to do on the red-marker round
The moment the red marker appears, spend the whole round on defense:
- Cast Shellga with Lasswell on Leah (25 MP), or Shell on the weakest characters.
- Heal everyone to full with Cura on all (Lid with Warrior of Light or Lasswell with Leah), or use a Mist Potion.
- Have anyone left over Defend.
- Keep Fina’s Light Veil up (12 MP, “Activate a barrier on all allies that nullifies a status ailment or debuff once”).
Keep Light Veil active: Heavenly Wind may inflict Sleep, but none appeared while the veil was up. Once the attack is over, revive any fallen character with a Phoenix Down, which restores 25% HP, and heal the party before the next red marker. Avoid letting Gravity from the minion hit anyone during that interval.
How to stagger Aether
Aether’s yellow stagger gauge drains slowly from Blizzara and regular attacks, taking about 9 rounds in one Normal attempt (the general rules are in stagger explained). Lasswell’s Limit Burst Null Moon speeds it up: “Deal non-elemental physical damage to an enemy. Target is more easily staggered for 3 turns.”
Null Moon followed by one more hit, Fina’s Shining Arrow, staggered him. “STAGGERED” appears and Aether turns purple.
Spend that window on Limit Bursts. Rain’s Infinity Drive reads “Deal Fire physical damage to an enemy. Damage increases by 50% if target is staggered.”, and Fina’s Holy Ray (“Light magic damage to all enemies”) hit Aether for 898 and the minion for 692.
A stagger may also trigger SELECT RESONANCE, with Hibernal Fury, Healing Wind or Crystal Braver available according to the equipped Visions. Hibernal Fury deals Ice damage and is the strongest choice here; see the full Resonance list for other options. Even during a stagger, Aether lost only about 10% of his HP. At Lv 18, expect a long fight: he still had over 80% HP after roughly 12 rounds.
If the party falls: Retry, or change the difficulty
When the whole party falls, the screen offers Retry, Load and Return to Title beneath “The party has fallen…”.
Choosing Retry prompts “Retry this battle from the beginning?” with No selected. It starts the battle over with full HP and MP without loading your save.
If repeated attempts fail, choose Load from the battle System Menu (Esc) to return to the boss save. Once back in the field, go to Options > Gameplay, change Difficulty to Casual (“Change battle difficulty.”), press R Apply, and confirm. You can return to Normal using the same steps. The difficulty settings are explained in more detail separately. That is how we finished the fight: on Casual, after three losses on Normal.
After Aether
After the battle, Aether kneels as the Invincible airship takes off. The objective updates to “Go to Dilmagia, the machinopolis” on Dirnado’s World Map, and the game autosaves. Find the upcoming fights in the bosses list; continue along the route in the full Final Fantasy Resonance walkthrough.
