An Ultra Ball has a catch rate of 2× the normal Poké Ball's catch rate. It is more effective than a Great Ball. It can be obtained by crafting it, buying from a shopkeeper, or as a tier 1 special drop,
To craft an Ultra Ball lid, two cooked Black Apricorns and one cooked Yellow Apricorn are needed. Placing the three cooked Apricorns in a row horizontally in a crafting table, with the yellow one in the middle, will make an Ultra Ball disc, and then using it with an anvil and a hammer will make an Ultra Ball lid.
Ultra Balls used to be crafted differently. This recipe no longer works.
