There is an alternitave thats cheaper and faster than the two Humify You need to do the second lunar magiks quest to acess it though Basically you get a water staff and you can just kill harpie swarms for fires or buy a steam staff for 1.6m Anyway Astrals are 140 each so it only costs 140 each spell :D You pretty much just use the spell and have empty vials then once it's over you empty and repeat this is 1.5x faster than the time it takes to do a high alch spell and it's more exp I guy wrote this in his blog(not my exact words) and got 70-87 mage in 2 weeks Beat that with high alching or teleing
