You must have ANCIENT STONE GATE and BARREL to make AMPHORA. This item belongs to feet category. Do not have caffeine after planting this one... It is going to take awhile. Low level players can use these to level up. Hitting it will break it but you need to count the hits yourself. You get at least 1 seed back (maybe more!) from splicing AMPHORA. Will you strike it rich? You just have to count the gems yourself. Blockratio of AMPHORA is a mystery. Maybe you can check the wiki for <a href="https://growtopia.fandom.com/wiki/Amphora">amphora</a>
