Hi,
There is a place calls Npc Area in most of private servers.
so in my server there is a npc that sells stones ؛
so i need my char when stones end from his inventory, go an buy from this npc and then continue alchemy.
there is a plugin or script thats allows me to do this?
Thx!
Its rather simple 
Make a condition. Item count <= 1 means if there is 1 or less items of the type in your inventory, it starts an action.
In this case, execute script.
You can make a script buying the stone you need.
However, a script wont be able to resume your alchemy (if you teleport, alchemy items also get removed from the bot list).
But this should at least help you restock the desired stone
nice,thank you
