Judging by the nature of potions, this value probably depends on your HP level. So, you can only get the desired '12 hp per potion' if you have a high hp level. If you have a low hp level, you will only get a measly 6 hp per potion. However, if this value is actually random, it's worse. You can't really predict if the potion will really be that efficient. Can anybody do some tests to see the actual nature of Barbarian Mixes? no, you make mixed potions by adding roe or caviar. roe heals 3 and caviar 6 per dose( or the other way round:p) Also, zamorak brews require torstol rather then dwarf weed=] nice info btw
