Formerly a bustling marketplace, the ward is ravaged by various disasters when you first enter. Wriggling plants from the strange going-ons of the park are scattered throughout the streets, which are ravaged with chasms from earthquakes.
The Salon is the first building you'll see upon entering the Obsidia Ward. Employees here greatly care about Pokémon's happiness, and they know a lot about it, too-One employee can tell you how much your Pokémon likes you, and another will give you a Soothe Bell if you've raised your Pokémon to be happy enough to satisfy her. A third employee will groom your Pokémon for 1500 once per day, which raises its happiness.
Located across the street from Critical Capture is an economic giant so powerful that nearly all nearby businesses went bankrupt. The Devon employees cheerfully remind you of the Devon Corp's great history, its bright future, and its present that you are strictly forbidden from knowing too much about.
Next door to the Devon Corp is a multicolored sugar craze. Children dash through (and sometimes on!) the shelves of treats that delight humans and Pokémon alike. In the back of the shop is a tile puzzle in the shape of the store's mascot, a Pokémon as sweet as their products, and solving it earns you a Swirlix of your own! This puzzle can be repeated for the same reward endlessly.
In the back of the store is a vending machine. A child stares longingly at it, penniless for her greatest desire-Chocolate Ice Cream. If you give her some, she'll happily thank you for it and leave to eat it outside, giving you access to the vending machine.
After receiving Cut, the Day Care Center next to the Pokémon Center can be accessed. However, as soon as they recognize the player, they suddenly remember that they're "actually closed". Talking to either one of them repeatedly results in their mood becoming more and more irritated, until eventually the pair give up and reveal their true identities-Members of Team Meteor!
After defeat, the pair explain their scheme and admit they locked the real Day-Care Couple away somewhere else, with the key hidden somewhere else. The Warehouse Key can be found in the house in the now-opened park, and it opens warehouses in the Coral Ward.
A woman inside the center is concerned about her son, lost in the current chaos. Locate him in South Obsidia Ward next to the Glamzonia Salon and return him to her to receive an Ability Capsule. (Note: You must solve the problems at the Obsidia Park before the boy can return to the Center)
After meeting Amaria in the Coral Ward, Amaria and Florinia meet the player outside the park and Cut their way inside after giving the player TMX1 (Cut). Amaria and Florinia head on inside, but just as the player steps in, they hear the screams of Amaria up ahead.
As they approach the center of the park, they see a terrible sight: Amaria and Florinia have been captured by a Tangrowth attached to some ghastly machine-and worse, a member of Team Meteor stands in front of it! The member introduces themselves as ZEL-three times, in fact. They explain that the machine is the source of all the damage throughout the town, amplifying Tangrowth's power so it can make mass weapons out of even the smallest root! They dare the player to attempt to stop it, and battle them using the Tangrowth, still hooked up to the machine and using it almost like a Mega Stone.
After the threat has passed, Amaria and Florinia agree that there is more to the situation than realized, and head their separate ways.
With the overgrowth removed, the park and its Pokémon are now accessible to the player.
Note: you must do the main story quest involving Devon corp first before you can do it. you can initiate it if you want. but you must continue the main story to complete it.
To trigger this quest. You must first head to the jasper ward into Rhodocrine Jungle. then enter Kecleon Cave (previously one one of the caves where a missing cop was located). you will See a Treecko in a cage. However there is an "unseeable object" blocking your path. soon all of the Jasper ward is filled with them. Then enter Silph CO's Branch Headquartersand talk with the green haired woman. she will ask the player to enter Devon Corp building and find the Devon Scope.
after you enter the building. there will be a homeless to defeat before you can proceed. after you enter the room. You will get: TM82 Dragon Tail, Electric Memory, and the Devon Scope.
Talk to the lady again and she will give you the Silvon Scope. Later return to the Kecleon Cave and battle all the kecleons.
In a small space in the alley lives a family of Plusle and Minun. A member of the family will investigate the player, and if they have PokeSnax, join them. Only one will be able to join, and it will know either Wish or Sing, an Egg Move.
This encounter cannot be completed after progressing to the Onyx Ward until after the gym has been cleared.
In the very back of the alley (at night), a pair of stray Mightyenas are ganging up on an Electrike. After defeating them, Electrike will wish to join your party, but will disappear if refused. Electrike knows a random Egg Move (Crunch, Flame Burst or Ice Fang)
Note: Similar to the Scraggang battle, these Pokémon cannot be caught.
There is a Litleo eating in the alleyway that will run off when approached by the player. The Litleo can then be found hiding in the house west of the pokemon center, but will again bolt at the sight of the player, running downstairs into the east Railnet Entrance. As the player corners them, a level 35 Klinglang descends from the ceiling and attacks. After defeating the Mechanightmare, Litleo will join your party.
Though Klinklang is too high a level to take on with just one badge, the cave can be collapsed with two uses of Magnitude. Numel, located in the Lower Peridot Ward during rain, can learn this move at level 12.
If the player brings Glamzonia Salon's Glameow to Central Salon's groomer, she will fight you. If you win this fight, you will receive a Bounsweet with Play Rough and Synthesis.
Being a Lv. 45, Tsareena will tear your team apart if you try it as early as possible. With only one Badge, your best bet is to inflict a burn (for example, with Slugma's Flame Body - one can be bought in Onyx Arcade) and bring a Pokemon that can reliably take a hit to this fight to abuse healing spam.
