How to Beat Astos
Introduction
Astos is the fourth boss in Final Fantasy 1 Pixel Remaster, a dark elf who’s been masquerading as the king of the Western Keep northwest of Elfheim. Hand him the Crown after the Piscodemons fight in Marsh Cave and he drops the disguise on the spot. There’s no negotiation and no escape; the fight starts the moment you trigger the dialogue.
This is the first FF1 boss with a real move set. Astos picks from nine different moves each turn, and the headline among them is the instant-kill Death spell. With 420 HP, no elemental weakness, and a punishing 170 Magic Evasion, you’ll need to grind him down with physical damage. Pack 2-3 Phoenix Downs and at least Cura on your White Mage before walking into the throne room.
A few numbers worth flagging. Magic Evasion 170 is the highest you’ve faced; offensive spells almost never connect, so don’t waste your Black Mage on Thunder or Fire here. Magic Defense 0 is the catch: if a spell does land, it lands for full damage, but with that evasion wall you can’t bank on it. Hits per turn: 1 keeps his physical pressure light, but his spell turns are where the danger is, and Astos’s Death cast is a one-shot kill on a successful hit, no HP threshold. Phoenix Downs are non-negotiable. Drop rate 4% on the Mythril Sword is double Garland’s drop chance but still works out to roughly 25 attempts for a guaranteed grab; not worth farming. Total fight rewards: 2,250 EXP, 2,000 Gil, your biggest payday so far.
Strategy
Quick Tips
- Bring Phoenix Downs
Death rolls at ~11% per turn. 2-3 Phoenix Downs keeps the fight recoverable if it lands.
- Skip offensive magic
170 Magic Evasion makes almost every spell miss. Only buffs are worth casting.
- Haste your fighter first
Astos rolls 11% Haste on himself each turn. Beat him to the buff and end the fight before his physicals double.
- Heal preemptively
Fira, Thundara, and Slowra chip the party between Death rolls. Don't wait for low HP.
- Physical attackers carry
Defense 18 is unremarkable; weapons go through it without much trouble.
To beat Astos in FF1, focus entirely on physical damage and keep Phoenix Downs in your inventory for the inevitable Death cast. Open with Haste on your strongest melee character, then stack Temper turn after turn. With 420 HP and no resistances, a Hasted, doubly-Tempered Warrior with a Pravoka or Elfheim weapon will end this fight in three or four rounds, well before Astos cycles back to a second Death.
The trap on this fight is trying to outdamage him with your Black Mage. Magic Evasion 170 means even Thunder will whiff the majority of casts. The numbers feel especially deceptive because his Magic Defense is technically zero, so the rare spell that connects looks great, but the math on reliability never works out. Spend those caster turns on buffs instead. Temper on your Warrior, Haste from the Elfheim shop on whoever swings hardest, and you’ll deal more damage in the same number of turns.
The Death cast is the wildcard. It’s a flat instant-kill on a successful magic hit and rolls at roughly 11% per turn, so over a 4-round fight you can expect one or two attempts. Phoenix Downs are the easy answer: keep 2-3 in the bag and revive immediately if Death lands. Cura preemptively rather than reactively, since Slowra and self-Haste both sit in the same rotation and can shift the fight’s tempo unexpectedly. If your Red Mage is in the party, they double as a backup Cura source in case your White Mage goes down.
Move Set
Astos has 9 moves and picks each one at the same chance every turn:
| Action | Effect | Chance |
|---|---|---|
| Fight | Basic 30-Attack physical | 11.1% |
| Death | Instant kill on a successful magic hit | 11.1% |
| Haste | Self-buff, doubles his physical hits for the rest of the fight | 11.1% |
| Slowra | Party-wide Slow | 11.1% |
| Slow | Single-target Slow | 11.1% |
| Sleep | Single-target sleep | 11.1% |
| Dark | Single-target blind | 11.1% |
| Fira | Single-target fire damage | 11.1% |
| Thundara | Single-target lightning damage | 11.1% |
Roughly a third of his moves are single-target debuffs (Sleep, Dark, Slow) that mostly miss or waste their effect against an armored front line. The genuinely dangerous picks are Death and the self-Haste; if Haste lands early, his physical pressure compounds for the rest of the fight, which is the strongest argument for ending the encounter fast.
Battle Plan
- Warrior / Monk: Attack every turn. They are your only real damage source in this fight.
- Black Mage: Cast Haste turn one, then Temper on your top damage dealer every turn after. Skip offensive spells.
- White Mage: Cura whenever anyone drops below 30 HP. Phoenix Down a fallen ally immediately if Death lands.
- Red Mage / Thief: Attack normally. Red Mage carries a backup Cura in case the White Mage gets Death’d.
After the Battle
Astos drops the Crystal Eye along with 2,000 Gil and a 4% chance at the Mythril Sword. The Crystal Eye is the key item to focus on, and the next stop is Matoya’s Cave north of Cornelia, where the chapter walkthrough picks up the trade chain.
Before you leave, save and rest if you took heavy hits during the fight. The detour to Matoya’s Cave goes through random encounters on the way back, and a fresh Death cast wasn’t the only thing chipping your HP.
