Battlemage potion

A battlemage potion is a potion that combines the properties of a magic and super defence potion:
 * Magic will be boosted by 4
 * Defence will be boosted by 5 + 15% of the player's level (rounded down)

It can be made by a player with 80 Herblore by using a cadantine on a vial of blood, then adding a potato cactus to the potion. This grants the player 155 Herblore experience.
