High alchemy is a spell in the RuneScape MMORPG that allows players to convert certain items into gold. It is one of the most popular methods of making money in the game, as it is relatively easy to learn and can be used to make a significant amount of money. To use high alchemy, players must first have the required Magic level and the necessary runes. They must then cast the spell on an item that is eligible for transmutation. The item will then be converted into gold, and the player will receive a certain amount of experience in the Magic skill.
High alchemy is a very useful spell for making money, as it can be used to convert a wide variety of items into gold. This includes items that are commonly found as drops from monsters, as well as items that can be purchased from shops. High alchemy can also be used to convert items that are no longer needed into gold, which can help players to free up inventory space.
