Withered Wasteland Pokémon Center Guide

To unlock the Pokémon Center Rebuilding Kit, players must reach Environment Level 3 and spend 1,000 Life Coins. Once purchased, the kit is automatically placed over the Pokémon Center rubble for examination.
Rebuilding the four main Pokémon Centers in the game is necessary to complete the story, including locations in Bleak Beach, Rocky Ridges, and Sparkling Skylands (but not Palette Town).
Required Materials
Players must gather: 20x Lumber, 20x Stone, 10x Leaf, and 10x Vine Rope.
Lumber requires a Pokémon with Chop specialty (Scyther recommended). Stone can be found throughout the Wasteland, with additional sources from cracked red brick blocks. Leaf comes from pulling plants or using Cut on Tall Grass. Vine Rope drops from Bellsprout or can be obtained by cutting vines in caves.
Required Pokémon
Eight different Pokémon are needed, including: 1x Pokémon with Bulldoze Specialty (Onix), 1x Pokémon with Build Specialty (Timburr), 1x Pokémon with Chop Specialty (Scyther), and 5x additional random Pokémon.
Reconstruction takes until the next in-game day to complete.
