Thank you for this, it was very helpful.

ez

jitterseed + shuriken = poison shuriken

I think the chests in hallow town has a couple treasures.
I don't remember which one but i thiink one of them sold a modest treasure. might not have even been sold at hallow.

other than the treasure i havnt foudn treasure

let me know if im missing something ill try to add it in

i suppose ill start up the game tomorrow when i get home from work and look for all this
and ill add the ones youve listed @Northern Circuit
but this will take time im going to start a new game

due to the sheer quantities, knives are the best to make weak spirits.
knives + knives = Shurikens
knives/shuriken + shuriken = weak spirit
then the rest lines up as usual.

CAN NOT UPGRADE SILK OR ORES
as far as I know at least.

The potions all work the same, even the spirits plus natural ingredients.
Did something stupid, mixed fine ore and bountiful treasure to see if that would make something nice, just exceptional spirit.
Seems mixing anything odd with fine ore makes a strong spirit unless its something higher tiered such as the bountiful treasure.

OH HO HO
Leucosic Bomb + Strong Spirit = Xanthosic Bomb
Xanthosic Bomb + Exceptional Spirit = Iosic Bomb
2 Iosic Bombs = Exceptional Spirit
2 Xanthosic Bombs = Strong Spirit
2 Leucosic Bombs = Weak Spirit

A lot of mixtures end up in making one of the 3 spirits.
All the booze is the same
All the Potions are the same
treasure is upgraded with spirits
Ore and Silk don't seem to upgrade at all.

Did my experimenting, hope it helped.

Thanks for making it originally, you're the man.

shurikens are made from two knives
