This is a great way to make gold in Runescape. Mining clay only requires 1 mining. Having a good pickaxe will make this faster so you might want to look into getting that. You will also need 14 buckets of water or the humidify spell.
You can mine Clay to the south of Varrock and just north of the Champions Guild. Mine a full inventory and head to the bank. Now use your buckets of water with the Clay, you can still make good money without using the buckets of water if you don’t want to. Either way both Soft Clay and Hard Clay will sell for around 100 – 200 gp and it’s a great way to make money quickly in Runescape, especially for low level players and f2p players.
