differance from 2 to 3 is instead of vox's dust use violet tri-tube sap...intead of crude potion vial use rough potion vial
difference from 3 to 4 is intead of Acaana,flamewort and comfrey leaf use sprig...instead of violet tri-tube sap use blue vervain bulb....potion vial is a makeshift potion vial
difference from 4 to 5 is instead of blue vervain bulb use betherium bark....simple potion vial for this one
difference from 5 to 6 is instead of sprig use Acaana,Flamewort,Comfrey,Bugbane and a plain potion vial
that should take you up to 178 in alchemy :) gl
