An advanced cocktail kit is an item that can be converted into any advanced beach cocktail. It can be obtained from The Beach activities or from defeating Clawdia during the event since 2022. It was originally obtainable from Treasure Hunter during specific days of the Phoenix Lamps promotion during the 2021 Beach event.
Ironman Mode players cannot normally obtain this item, or any type of cocktail, but if one is somehow obtained (such as through a beach party ticket) any resulting cocktail will refer to the player's "Ironman constitution" preventing it from taking effect.
Selecting "Create Cocktail" opens a menu with the following options on the left, with their explanations and the option to create the cocktails on the right.
