below i list some general spoilers for which mats are good for which things not big spoilers just guidelines, not going to say how many of each thing etc
-pure zun isnt evil it's balanced but that also means it's plain -hash is better for healing as well as shrooms (silan tells us so!) -excellent loot is usually comparible to supreme dig mats, not far behind mathematically
-sap load mats are a good idea for staff (shu, mitexi i think from memory)
-if you are a heavy sap crystal user like me you can just ignore speed and go for elemental and heal POWER, in this case 95% amps with good sap load are possible with just excellent loot in the magic focus section (ele heal 95% and 2000 sap load something like that)
-walk aorund with lots of enchants in your bag to switch to different ele and heal spells -lock one of the spells to separate which are heal and which are ele
