I having the hardest time making weapons and armor can i get some advice
i was good now i can make anything over lvl 12 plz help

lvl 12? random, try compounding wood + grass, or vice versa
like cypress wood + snow grass, etc..

Alchemy is really like a secret knowledge of witches,
One may try to put random things in cauldron and watch what will happen,
but this way only trash or low value things will comes out.

Try to understand how it works and you will be able
to create any item you want.

Knowing rules which rule Alchemy will even allow you
to obtain rare items that are wanted by many people but very hard
or at first look impossible to obtain.

Rank 6 and above, a bit hard for not spending money at all for those, but u can use many trash to up the rank. Since it may have many same element within the compound range, u might get different result.

alchemy is pretty simple it has few rules that when u keep u get wahtever u want
there is still chance of fail but that alchemy is
i dont much understand waht he asking but i guess he is tryign to make higher lvl things just try to buy those 8-122 mats and start making simple compound
there are lots on compound guides on forums u need search for them they will usefull to you
just be careful with the not comfimed reactions here soem of them are faulse and dont try superior formulas on primery or other ones like that
