Clay is an alchemy ingredient and one of the earliest used in the game.
Clay is only used to two formulas near the start of the game; later on as the player phases these formulas out of their alchemy list, they have virtually no need for Clay.
The alchemists in Prehistoria offer the cheapest price on Clay by far. If the player wants to use Hard Ball and Defend often in the future, they should stock up on Clay early.
