The table below shows costs of making Barbarian mixes using live data from the Grand Exchange Market Watch. The final column also calculates the profit per Herbloreexperience point for each particular potion.
Note that Barbarian potions are made from 2-dose potions. The figure in the final XP profit column takes this into account by using the price of the 2-dose potions.
Note:Magic ess. mix (2) is made by mixing Caviar with a two-dose Magic essence potion. The regular potion is untradeable, however the Barbarbian mix can be traded. The cost of vials of water is included in the final calculation.
