Karatom the Gestral

Quest given by Karatom the Gestral in Gestral Village.

In the Gestral Village, past the Gestral Bazaar, you can find a young gestral named Karatom. He is the gestral responsible for building the Ultimate Sakapatate and other Sakapatate defenders. Speak to him and he'll mention that he wants to make the Ultimate Sakapatate stronger, but he requires a "mushroom" that can strengthen his invention. The item you'll need is the Mushroom, which is located in Esquie's Nest. Just as you pass through the guard, when you enter, look to your right and jump down. You'll see a Mime enemy. From where the Mime is, look to your left and you'll see a cluster of mushrooms on the ground. Approach it to find the Mushroom on the ground. Return to the Gestral Village and give the Mushroom to Karatom. You'll now get to fight the improved Ultimate Sakapatate in a 1v1 battle as Gustave. If you lose the fight, you can speak to Karatom and have a rematch. Simply defeat it to acquire 3x Polished Chroma Catalyst and 1x Pure Outfit (Gustave). Note: you cannot complete this fight after progressing to next ACT but it is not required for the trophy/achievement
