How To Beat Jasmine in Pokémon HG/SS

Jasmine's Battle Vignette in Pokémon HeartGold

All of Jasmine’s Pokémon are weak to Fire, Fighting, and Ground-type moves. The ideal Pokémon to use against Jasmine is Quagsire, because it can learn plenty of Water & Ground-type moves. Plus Quagsire is immune to Electric-type moves and resists all of Steelix’s moves.

Steelix heavily resists physical attacks, so make sure to use special attacks if possible. Moves like Flamethrower, Surf, Focus Blast, and Earth Power are extremely powerful moves for this gym battle – regardless of which Pokémon in your team can use them.

If you want to follow our strategy, then you can get a Quagsire by evolving a Wooper at Level 20. You can catch a Wooper in the tall grass on Route 32 (just below Violet City). You can also encounter wild Woopers or wild Quagsires in Cliff Cave during the day, and by surfing anytime on Route 32, Union Cave, and the Ruins of Alph.

How To Defeat Jasmine (Quick Guide)

Here is a step-by-step overview of our recommended strategy:

  1. Lead the party with Quagsire.
  2. Spam your chosen Ground-type move against her Magnemites.
  3. Spam Surf against Steelix until it faints.

Jasmine’s Team

Jasmine focuses on Steel-type Pokémon, the most dangerous of which is her Steelix.

Pokémon Level Type/s Ability Held Item Moveset

Lv. 30 Electric/Steel Magnet Pull
Prevents Steel-type Pokémon from escaping.
  • Thunderbolt
  • SonicBoom
  • Supersonic
  • Thunder Wave

Lv. 30 Electric/Steel Sturdy
The Pokémon is protected against 1-hit KO attacks.
  • Thunderbolt
  • SonicBoom
  • Supersonic
  • Thunder Wave

Steelix (♀)
Lv. 35 Steel/Ground Sturdy
The Pokémon is protected against 1-hit KO attacks.
Sitrus Berry
  • Iron Tail
  • Rock Throw
  • Sandstorm
  • Screech

Although Steelix is the main threat, you should not sleep on her two Magnemite. Their STAB (Same-Type Attack Bonus) Thunderbolt can prove deadly to Water- and Flying-types, and Thunder Wave and Supersonic can prevent your Pokémon from attacking.

Magnemite have relatively low Speed stats, so it’s easy to counter them with super-effective moves. Magnemite are weak to Fire-, Fighting-, and Ground-type moves.

Note: Although they appear to be floating, Magnemite and its evolutions are not actually immune to Ground-type moves.

As for Steelix, it has a staggering 200 base Defense, the second highest of all non-Legendary Pokémon only beaten by Shuckle. Unlike Shuckle, however, Steelix has significantly better HP and offensive capabilities, making it an extremely formidable foe.

Fortunately for us, it has a few weaknesses that we can exploit.

  1. Firstly, Steelix has poor speed stats. We’ll be able to reliably out-speed it with our Pokémon if they are similar in level with Steelix.
  2. In addition, Steelix’s Ability Sturdy works differently in Generation IV and below. Unlike in the more recent Pokémon games, Sturdy only negates moves that specifically deal One-Hit KOs (like Horn Drill and Guillotine), instead of affecting all moves.
  3. And while Steelix may have extremely high Defense stats, it has mediocre Special Defense stats. We’ll have an easier time defeating it by using special moves like Surf or Flamethrower.

This means we can still attempt to faint Steelix in one turn if we have a strong enough Pokémon.

Note: We have only listed locations that are accessible at this point in the game.

Jasmine is one of the more straight-forward Gym Battles, where you can win by simply using Type advantages.

Since there’s not a lot of nuances to her strategy, we will focus on Type matchups for this guide.

Ground-types are at a major advantage for this fight, since they benefit from STAB super-effective moves and are also immune to Jasmine’s two Magnemite.

  • Quagsire has access to Mud Bomb, one of the few special Ground-type moves. It also has access to both STAB Earthquake and STAB Surf, two of the most powerful moves of their Types. We chose Quagsire in this guide for these reasons.
  • Typhlosion and Feraligatr will work well for this fight because they both have STAB super-effective moves, and they can both learn Focus Blast, a special Fighting-type attack.
  • Meganium will not be able to deal any significant damage to Steelix, but it can stall out the battle with Leech Seed as long as you keep your Pokémon healthy with Synthesis or Recovery Items.

Our Team Comp

The team we used for this guide is as follows:

Pokémon Type/s Level Ability Held Item Moves
Quagsire Water/Ground 36 Water Absorb
Restores HP if hit by a Water-type move.
Quick Claw
  • Earthquake
  • Surf
  • Rock Smash
  • Amnesia
Dugtrio Ground 33 Sand Veil
Boosts the Pokémon’s evasion in a sandstorm.
  • Earth Power
  • Dig
  • Sucker Punch
  • Mud Bomb
Cyndaquil Fire 35 Blaze
Powers up Fire-type moves in a pinch.
  • Lava Plume
  • Swift
  • Leer
  • Smokescreen

In theory, you should be able to solo this fight with just Quagsire.

But we decided to bring other Pokémon just in case.

Getting a Quagsire

Quagsire evolves from Wooper starting at Level 20. Wooper encountered in the tall grass on Route 32 will be very low level, so we recommend encountering them while surfing.

You can catch Wooper and Quagsire by surfing in the water on Route 32, and in Union Cave and the Ruins of Alph.

Once you catch either a Wooper or a Quagsire, train them until they reach at least Level 36.

They will naturally learn the required moves for this gym battle as they level up.

Quagsire learns:

  • Mud Bomb at Level 19
  • Earthquake at Level 36
  • You should also have HM03 Surf at this point in the game, so also teach them Surf as well

Tip: Wooper learns Earthquake earlier at Level 33, so you could wait to evolve into Quagsire until Lv. 33 for less grinding.

Useful Technical Machines

If you prefer not running any of our recommended Pokémon in your team, you could teach your existing Pokémon some coverage moves that will greatly help in your battle via TMs.

TM28 Dig is the only Ground-type TM available at this point in the game.

It’s a two-turn move that deals damage during the second turn, like Fly and Dive.

TM28 can be found in the National Park, behind the upper fences. There should be a gap between the fences next to the boy playing with a handheld console.

Enter through the fences and head left then straight down. The TM should be barely visible behind an indent in the trees at the bottom.

And there are other TMs that you can obtain from the Goldenrod Department Store that will be useful for this Gym Battle. We’ve listed them below, along with the recommended Pokémon to teach them to:

TM Type Category Power Acc. Location Recommended Users
TM52 Focus Blast Fighting Special 120 70% TM Corner (5F) Nidoqueen, Nidoking, Golduck, Slowbro, Hypno, Magmar, Typhlosion, Feraligatr, Ampharos, Quagsire
TM38 Fire Blast Fire Special 120 85% TM Corner (5F) Nidoqueen, Nidoking, Ninetales (SS), Arcanine (HG), Slowbro, Weezing, Magmar, Flareon, Typhlosion, Togetic
TM60 Drain Punch Fighting Physical 60 100% Lottery (6F), on Thursdays Hypno, Vileplume, Bellossom, Slowbro

Note: We have only listed Pokémon that are available at this point in the game. Bold indicates STAB.

Battling Jasmine

Jasmine will begin the battle with a Magnemite. We will lead with our Quagsire.

Have Quagsire use Mud Bomb or Earthquake. It should easily OHKO the Magnemite.

Jasmine will then randomly send either her second Magnemite or her Steelix. If Jasmine sends out her second Magnemite, just use the same move on it again.

If she swaps to her Steelix, Use Surf instead.

You should be able to take down Steelix in one or two turns.

Once Steelix falls, the fight is essentially over.

Just deal with the remaining Magnemite (if any), and you will have won the battle.

After defeating Jasmine, she will award you with the Mineral Badge, as well as TM23 Iron Tail.
