You’re wandering around the Corel Desert in a Gold Saucer desert rose colored haze, feeling like a god because you finally got that Gold Chocobo. Then you see it. A red claw sticking out of the sand. You touch it, the screen swirls, and suddenly the music shifts into that frantic, high-stress boss theme. Within thirty seconds, your party is dead. Most of them didn't even get a turn. That is the Final Fantasy 7 Ruby Weapon experience in a nutshell. It’s not just a boss fight; it’s a traumatic rite of passage that has defined "superboss" logic for every RPG that followed.
Honestly, Ruby is a jerk.
While Emerald Weapon has that terrifying countdown clock and massive HP pool, Ruby is the one that actually plays dirty. It ignores the rules. It removes your friends from the field. It makes you feel small. Even back in 1997, when we were all sharing blurry screenshots on GeoCities pages, the consensus was clear: if you didn't have a very specific, almost "cheaty" plan, you were toast.
The Mechanics of Why Final Fantasy 7 Ruby Weapon is a Nightmare
Let's talk about the Whirlclaws. This is the move that makes everyone rage-quit. If you enter the fight with three party members standing, Ruby will eventually use Whirlclaw to eject two of them from the battle permanently. Not "knocked out." Not "dead." Gone. Deleted from the combat tracker. You're left staring at Cloud (or whoever your lead is) trying to solo a monster with 800,000 HP.
Because of this, the "pro" way to start the fight is actually to kill off two of your own characters before the battle even begins. It sounds stupid, right? You enter a fight with two ghosts, and only once Ruby digs its claws into the sand do you revive them. This "tricks" the AI. It’s one of those weird, meta-gaming quirks that makes the Final Fantasy 7 Ruby Weapon encounter so legendary.
Defense is a Lie
Ruby has a Defense stat of 256 and a Magic Defense of 256. In the original PlayStation code, that basically means your standard attacks are going to hit for double-digit damage. Your fancy Comet 2 or Ultima? It’s doing nothing. To actually hurt this thing, you need attacks that ignore defense entirely. We're talking about the big guns: Knights of the Round, Bahamut ZERO, or Coin (if you’re feeling spicy and have a few million Gil to throw away).
But there's a catch. Every time you summon a multi-hit monster like Knights of the Round, Ruby counters with Ultima. It’s a vicious cycle of "I hit you hard, you hit me harder."
The W-Summon and Mime Loop Strategy
If you want to beat it the "standard" way, you basically have to become a machine. You need the W-Summon Materia, which you get from the Battle Square at Gold Saucer. You pair that with Knights of the Round. Then, on every subsequent turn, you use the Mime Materia.
Mime is the MVP here.
It allows you to repeat that massive, 13-hit summon without consuming any MP. Without this loop, you'd run out of juice in five minutes. Even then, you have to manage your HP. Every time Ruby counters with Ultima, you're teetering on the edge of a Game Over. This is where the Final Attack + Phoenix Materia combo comes in. It’s your insurance policy. If you die, Phoenix brings everyone back. It's a safety net, but it only works as many times as your Materia level allows.
Why Hades is Secretly the Best Materia Here
A lot of players overlook the Hades summon. In most of Final Fantasy VII, Hades is just a weird, creepy pot that causes status effects. Against Ruby, it's a godsend. Ruby is actually susceptible to Paralyze. If you cast Hades (or use an ink/paralyze item), you can freeze the Weapon in place for a few turns. This gives you a breathing room to heal, set up your Big Guard, or just take a second to stop your hands from shaking.
The Lore vs. The Gameplay
There’s always been this weird gap between what the game tells us and what we experience. The Weapons were created by the Planet to be a defense mechanism against Jenova. But when Sephiroth summons Meteor, the Weapons just... wake up and start wrecking cities. Ruby is chilling in the desert near the Gold Saucer. Why? Is it guarding something?
Theoretically, it's there to stop anything that threatens the Planet, but by the time you fight it, you're the strongest thing on the planet besides Sephiroth. Maybe Ruby recognizes that Cloud and his band of eco-terrorists are just as disruptive as the meteor. Or maybe, as some fans have theorized for decades, it's just a mechanical "gear check" meant to ensure the player has mastered the Materia system before the final descent into the Northern Crater.
The reward for all this suffering? The Desert Rose. You take it to the old man in Kalm, and he gives you a Gold Chocobo.

Let's be real: by the time you can kill Ruby, you probably already have a Gold Chocobo. You needed it to get the Materia required to kill Ruby! It’s a classic RPG paradox. The prize is useless because you had to be powerful enough to not need it just to win it. But that's not why we do it. We do it for the bragging rights. We do it to see that massive red sprite dissolve into white light.
Common Mistakes People Still Make
Don't use Ribbons.
Okay, that’s an exaggeration—Ribbons are great—but they don't stop everything Ruby throws at you. People think a Ribbon makes them invincible to status effects, but Ruby’s "Shadow Flare" and "Ruby Flame" are pure, raw damage.
Another mistake? Ignoring the tentacles. When Final Fantasy 7 Ruby Weapon sinks its claws into the sand, they pop up behind you. These tentacles drain MP and HP. If you don't kill the tentacles, or at least keep them managed, you'll find your MP at zero just as you're about to cast your winning spell. It’s a resource drain fight as much as a damage race.
- Prep Work: Go to the Sunken Gelnika. Farm those Power Sources. If your Strength and Magic stats aren't maxed out, Ruby will laugh at you.
- The Dodo Method: Use the "Dodo" strategy. It involves using the item "Dazers." It’s a cheap way to keep Ruby paralyzed the entire fight. It feels like cheating, but hey, Ruby echelons you out of the fight, so it started the unfair fight first.
- Megalixirs: You should have dozens of these. Don't hoard them. This is the fight they were made for. If you're waiting for a more "important" battle, you're going to die with a full inventory.
The Legacy of the Desert Terror
When the Final Fantasy VII Remake and Rebirth projects started, the first thing veteran players asked was, "How are they going to handle the Weapons?" We've seen glimpses, and we've seen the scale of the world, but nothing quite matches the isolation of that desert encounter in the 1997 original.
There's something uniquely terrifying about a silent, looming monster in a low-poly desert. It doesn't have a dialogue tree. It doesn't have a tragic backstory. It's just an evolutionary dead-end of planetary defense that wants you dead.
Beating Ruby isn't about skill in the traditional sense; it's about preparation. It's a puzzle. Once you have the pieces—the W-Summon, the Mime, the Final Attack + Phoenix, and the patience to watch the Knights of the Round animation for the 50th time—the fight becomes a rhythmic, almost meditative process of survival.
Practical Steps for Your Next Attempt
If you're loading up a save file today to finally settle this grudge, follow this checklist.
First, go to the Northern Crater and master your Materia. You need those stars. Specifically, make sure your HP Plus Materia are high enough that every character is sitting at a comfortable 9,999 HP. Anything less and Ruby's "Ultima" counter will end your run instantly.
Second, go to the old man in Kalm and make sure you haven't already traded away items you need.
Third, and this is the most important part: set your Battle Speed to slow in the config menu. There is no shame in this. The ATB gauge in FFVII can be unforgiving when a boss is as fast as Ruby. Giving yourself those extra fractions of a second to navigate the menu and find "Mime" can be the difference between a victory and a "Close App" moment.
Finally, kill off two party members before you touch the claw. It’s the only way to guarantee you keep your team. Once the fight starts and the claws are in the sand, use a Life2 or a Phoenix Down immediately. Now you're at full strength, and Ruby's AI is effectively neutered from using its most annoying move.
Go get that Desert Rose. Even if you don't need the Chocobo, you need the satisfaction. It’s been thirty years. It’s time to win.
