To make a Knight in Little Alchemy 2, you will first need to combine a Human and a Horse. To do this, select the ‘Human‘ element from your library and then the ‘Horse‘ element from the library. Drag the horse onto the human to combine them into a ‘Rider‘ element. Then, you will need to combine the ‘Rider‘ element with a ‘Sword‘. To do this, select the ‘Rider‘ element and then the ‘Sword‘ element, and drag the sword onto the rider. This will combine the two elements into a ‘Knight‘ element.
