After making their way through the jungles of the PULSE Machine to its location, the player encounters Taka, ZEL, and a mysterious agent defending it. Shortly after confronting them, Heather flies in, with her overly strong confidence and heroism. Heather argues strongly with the newcomer, and is left to battle them as the player battles Taka and ZEL.
A survivor of the disaster resides in this house ready to aide the player. On the top floor are a series of books detailing all the properties of Field Effects. In one room (accessed by traveling across the bookcase), an Ill-fated Doll can be found, along with a distressed Growlithe facing a large hole in the ground. Interact first with the Growlithe and then with the farthest end of the hole up against the wall to find the remains of a Police Officer who met a tragic end. The Growlithe will then depart to return to the station.
Later after defeating the Beryl Gym, if you clear up the trash in the Library and report to the Gothitelle, she will give the player a Soul Candle. One of the Gothita will also want to join player. It will always be female and come with either Mirror Coat or Dark Pulse.
After the reconstruction of the Beryl Ward, the player has access to a secret room. The secret room password is green, red, purple, yellow, blue, white. Inside the secret room, there is a TM for Solarbeam, a field effect read-out for the New World, and an article titled "Destiny's End".
Just to the left of the Beryl Gym is a path that leads to the Beryl Cemetery. This vine-covered graveyard has been quite damaged, to the point where some grave are unreadable, but a few can be made out:
During the night, the grave just to the left of the graveyard's stairs can be read, which will summon a Shuppet that attacks the player, If caught the pokemon's 4th move varies (pursuit, confuse ray). Afterwards, the grave cannot be read again.
During night, if the player has Soul Candle, they can use it on a large pumpkin to make Pumpkaboo appear and catch it. Its level varies depending on the pumpkin used. After city restoration, few extra pumpkins appear.
After meeting Shelly in Lapis Ward, but before reaching Agate Circus, you will find the ghost of Corry on the hotel roof in Beryl on a clear night. This ghost is really a Zorua in disguise, and finding it will prompt it to run away. Zorua's first hiding spot will be by the PokéMart in Peridot Ward, and its second will be in the abandoned hotel next to the Magma Hideout. Zorua is level 30 and will challenge you after interacting with it at this second hiding spot.
Trainers with a Vs. Seeker by their names, when alerted for a rematch using the item, may use higher-level Pokémon.
This is a tougher fight than the previous two as PULSE Tangrowth is now accompanied by a full team. A good idea is to lay Toxic Spikes (Beedrill - Lv. 25; Roselia - Lv. 28 and Trubbish - Lv. 7), which will affect most of opposing Pokemon, including Tangrowth who does not start as a Poison-type.
