Castelia Sewers

Castelia Sewers

When you go down the stairs, Hugh will be down there and he'll suggest you team up in order to take on Team Plasma. He'll join your party for a bit, causing every wild Pokemon in the area to be a Double Battle, except with Hugh and his starter Pokemon as the second Pokemon on your side of the field (he controls it, so it can be somewhat random).

Ah, Rattata. You actually don't run into Rattata until quite a bit later in the game compared to usual, so that actually gives it some fairly decent moves available quickly: it'll already have Bite and picks up the powerful Hyper Fang at level 16. It even gets Sucker Punch at level 19 and then evolves into Raticate at level 20, which gives it a necessary bump in stats. However, Raticate's stats are still pretty underwhelming; its Speed is good, but its Attack — its second highest stat — isn't great at all and will only suffice early on. Crunch at level 24 is the last must-have move Raticate learns, although there are still some interesting ones after that.

It does have access to learning a few odd TM moves, but most aren't available for awhile and aren't that useful for Raticate; instead, look to Dig early on as well as Return later in the game.

Comparing Rattata to Patrat is really the most important comparison. Their stats are mostly similar, although Raticate is substantially faster while Watchog has a bit better HP and Attack. Watchog gets Crunch before Raticate, but doesn't get Hyper Fang until much later. I'd say that, even though Raticate learns a lot of attacking moves, it lacks the additional strategy element that Watchog has, so I've gotta give the point to the Patrat family and recommend it over Rattata (although I don't recommend either for your team). But both are outclassed by Lillipup anyway.

Oh yes, just when you thought you'd be free of the nuisance known as Zubat, it makes a return down here. However, the interesting thing is that Zubat actually isn't so bad in this game thanks to the level you get it and the point in the game you get at. It also evolves into Golbat at level 22, which isn't too far away at all, and then into Crobat once its happiness is high enough and it gains a level (and now that you have the Bicycle and can give it a massage, you can do this pretty easily).

Good moves it starts off with right off the bat are Bite and Wing Attack (learns it at level 15, so the L14 one won't have it yet). Both are 60-power and Wing Attack even makes use of Zubat's Flying-type. Since the upcoming Gym is a Bug-type Gym (and uses a lot of Bug/Grass-type Pokemon), this is a great attack and is a better Flying-type Pokemon than Pidove to use against that Gym. It gets Confuse Ray at level 19 to spice things up and annoy the foes (it's a decent attack if used right), then, after evolving, it has access to moves like Air Cutter (meh) at level 28, Acrobatics (yesss!) at level 33, and, if you like to take a chance, Poison Fang at level 42. Air Slash at level 52 + Confuse Ray actually make a nice combo for a Crobat, although Cross Poison is a decent option. Getting back to Zubat, you can teach Venoshock to it right away to give it a decent Poison-type attack, and I highly recommend you do that as soon as you catch one.

Crobat's stats are actually really good. It's extremely fast and has very well-rounded other stats, capable of taking a hit, and hitting hard enough on either end of the attacking spectrum (although Physical-based attacks are still better). While towards the end of the game, it won't have quite the offensive oomph certain other Pokemon have, it has the advantage of being very versatile in its strategic attacks, letting you confuse the foe before it can strike, Protect + Toxic + Venoshock for massive damage and stalling, Acrobatics for heavy damage so long as you don't have an item, or you can just give it Fly for convenience (at the cost of power).

I never thought I'd say it, but I recommend Zubat. It finally has the right things going for it in this game. It gets good attacks for this point in the game, you don't get it too early (ugh Leech Life for 10 levels), and there aren't as many decent competitors for either Poison- or Flying-type Pokemon out there.

Lastly, we have Grimer, the smelly poisonous blob. Grimer focuses primarily on Attack and HP, but gets respectable Special Defense after it evolves into Muk at — get ready for it — level 38. Yeah, it's not going to evolve for an eternity and will be stuck with less than stellar stats the whole time.

The worst thing about Grimer and Muk is they learn no Physical-based Poison-type attacks to take advantage of their Attack stat; in fact, most of the moves they learn are Special-based. Really? Why, why would they do that? You get Gunk Shot at level 49 as a Muk. That's ridiculous (although it's still better than it was in Black and White). You're going to have to rely on TMs, and, thankfully, it can learn a lot of them, but since you don't get Poison Jab until after you've beaten the game, you're basically going to be using a Pokemon without too high of Attack using a bunch of TM moves that would be better used by Pokemon of the appropriate type. Do I recommend Muk? No way, definitely pass on this blob, or go with Zubat instead if you want a Poison-type. (Yes, I know it can learn elemental punches by move tutors, but so can Lucario, so really, don't bother.)

Hugh leads with his starter Pokemon at level 20, which should be pretty strong at this point in the game. Because of that, don't focus on catching Pokemon down here until after you two have parted ways. On the bright side, he'll heal you up after every battle, which is awesome.

Sewer Seasons!

Depending on which season it is, the water level in the sewers may be up or it may be low, giving you access to other areas, but also requiring different navigation instructions to get through. Please make sure you read the appropriate section if you notice the water levels are lowered!

Water-filled Sewers (Summer)

Teaming up to take on Team Plasma

Anyway, from the start, cross the bridge to the north and then take a left, following that path for awhile. You should eventually see two Plasma Grunts, as well as a TwistedSpoon right before them. Pick up the spoon and then challenge the Plasma Grunts. The first one uses a Scraggy L16 while the second uses a Sandile L16. It should be an easy fight thanks to Hugh.

After beating them, they'll run away like cowards, but then the Gym Leader, Burgh, will come walking out from another path. Hugh will then give you HM04 (Strength), which is an 80-power Physical-based Normal-type attack that actually hits pretty hard at this point in the game. It can be used outside of battle to push large boulders around, although keep in mind that you cannot forget this move unless you take the Pokemon knowing it to the Move Deleter in the Pokemon World Tournament (after the 5th Gym). 80 power should last you just fine until that point, though, and it's worlds better than Cut, so certainly consider it since Return probably isn't that strong yet.

This guy is rather interesting...

Once Hugh leaves, you and Burgh will start to head off, but then another voice will surprise you. Coming from the tunnel is a mysterious figure talking about Pokemon and such. He's an odd fellow, but doesn't bother to take the time to introduce himself, opting to walk off instead.

Burgh will head back to his Gym, letting you fight him whenever you want, although there's still a bit more you can do in this sewer system. First of all, you can head up north to enter the Relic Passage should you so desire, or you choose to continue looking around the sewers.


If you're continuing looking through the sewers, head on over to the west, into the room where Burgh came out of and you'll find a Heart Scale there. After you get your 5th Gym Badge, you can exchange these with the Reminder Girl to have her teach your Pokemon moves that it can learn by leveling up, up to its current level. This is very handy for reteaching moves you forgot that you want again, or also for learning certain moves that are only available at level 1 (Emboar gets Hammer Arm and Samurott gets Megahorn — both of which are pretty nice).

Now head back out and then south of where the Plasma Grunts, crossing a bridge. See the stairs that lead up? That takes you to the Castelia City Garden, where you can find some more wild Pokemon. Go ahead and check it out if you'd like, but, like the Relic Passage, I'm going to put it in its own section.


Exploring Castelia Sewers

Head south in the sewers until you see a Janitor running around. He'll challenge you with his Lillipup L16 and Trubbish L16. Just past him is a bridge leading west. Over there is an X Special. Keep going west and you'll find a Clerk ♂, but he won't battle you.

From that Clerk, head west across the bridge and then north. You'll find three bridges to cross now: two on the left and one on the right. The one on the right leads to a Worker who fights you with a Drilbur L17. Other than that, it's a dead end for now, so go back and take the left bridge, taking the branch heading left instead (you'll come back for the one heading up in a sec). Don't bother checking out anywhere west or south; just cross the bridge north now (the one on the left side) and follow the path there to find a Rare Bone.

The Leftovers are a helpful item to have.

Now go back to just past the Clerk, over by the bridge you didn't check out yet (it crosses north and is in the top-left corner of the little "island"). This takes you up to a Doctor, who uses a Sewaddle L17. After you beat him, he'll fully heal your Pokemon, so don't worry so much about the fight against him. You can head either west or east; heading west leads to an empty room, so ignore that. Instead, go east, pick up the Leftovers, which heals 1/16th your Pokemon's HP between each turn when held in battle (very nice!), and then enter that door.

There's a Researcher inside of that building who wants to see Poison-type Pokemon. She'll give you either a Potion, a Super Potion, or a Revive, randomly, and you can talk to her once per day.

This researcher will give you healing items each day

Water-drained Sewers (Autumn)

From the entrance, head down into the empty sewers and go west until you see two sets of stairs. Take the top set of stairs and then head west to find two Team Plasma Grunts that you must fight in a Double Battle, as well as a TwistedSpoon right before them. Pick up the spoon and then challenge the Plasma Grunts. The first one uses a Scraggy L16 while the second uses a Sandile L16. It should be an easy fight thanks to Hugh.

After beating them, they'll run away like cowards, but then the Gym Leader, Burgh, will come walking out from another path. Hugh will then give you HM04 (Strength), which is an 80-power Physical-based Normal-type attack that actually hits pretty hard at this point in the game. It can be used outside of battle to push large boulders around, although keep in mind that you cannot forget this move unless you take the Pokemon knowing it to the Move Deleter in the Pokemon World Tournament (after the 5th Gym). 80 power should last you just fine until that point, though, and it's worlds better than Cut, so certainly consider it since Return probably isn't that strong yet.

This is very handy for reteaching moves you forgot that you want again, or also for learning certain moves that are only available at level 1 (Emboar gets Hammer Arm and Samurott gets Megahorn — both of which are pretty nice).

Now head back to the drained sewer bank and now climb up the bottom set of stairs. See the stairs that lead up, just to your left? That takes you to the Castelia City Garden, where you can find some more wild Pokemon. Go ahead and check it out if you'd like, but, like the Relic Passage, I'm going to put it in its own section.


Head south for a little bit in the sewers until you see some stairs leading down into the bottom level. Remember this point for later on! There's a lot to do if you keep going south or if you take the stairs down, but we're going to start by taking the stairs down, then head south until you see some more stairs to the left. Go up them and pick up the X Sp. Def. Head back down and cross through the gate to the south, then go west, and finally north at the fork in the road (heading south leads to a dead end).

Just up there, you can either take the steps up or keep heading north. Start by taking the going north and then following the path until you climb up some stairs. You'll have to face a Researcher, who uses a Grimer L17. The room right next to her is, unfortunately, empty.

Go back to where the steps leading up were and take them up to find a Worker with a Drilbur L17 on his team. Take him down, then take the stairs right by him down and across over to a Doctor, who uses a Sewaddle L17, but heals you fully after the battle — you can talk to him whenever your Pokemon need healing.

Just to the right of the Doctor are some Leftovers, which is a great held item that heals your Pokemon's HP by 1/16 of its maximum after each turn in battle. Inside of the room right next to the Leftovers is a Researcher who is researching stuff in the sewers. She'll give you either a Potion, a Super Potion, or a Revive, randomly, and you can talk to her once per day.

Now, head back towards the beginning, back to those steps that I told you to remember. Yeah, those ones. Go south instead until you find a Janitor, who uses a Lillipup L16 and Trubbish L16. Follow that path until you find some stairs, which you can take and then head west for a very long time. You'll run into a branch that leads north and west; the north path just leads to a dead end, so keep heading west until you find a whole ton of stairs. Take those stairs up, fight the Worker there and his Timburr L17. Grab the Pearl right next to him, but unfortunately that's all there is there for now thanks to that one-way ledge.

Aftermath

Iris is eager to hear how it went

Well, that's about all there is to do down here in the sewers, although if you haven't checked out the Castelia Garden or the Relic Passage, now would be a great time to do so before taking on the Gym.

As you leave the sewers, Iris will tell you that Burgh went off to the Gym (thank you, Captain Obvious), so that sounds like the place you want to be!
