To make a Sword in Little Alchemy 2, you will need to combine Metal and Wood. Start out by dragging the Metal element onto the playing board. Then, drag the Wood element onto the playing board and combine it with the Metal element. Once both elements are combined, a Sword will appear. This can be used to solve puzzles and complete quests. Additionally, you can use the Sword to fight monsters, explore dungeons, and protect yourself from harm.
