How to use a specific item

I want the bot to use specific item, I guess that I have to use Conditions and Python to build, but I want to know how to use the funcion.

the opcode is: 0x7074
the data is: 01 04 A5 79 00 00 00

inject_joymax(0x7074, ‘01 04 A5 79 00 00 00’, False)

am I right or I have to use another function? I want to use a devil spirit in a private server called Silkroad Latino

If the item always exists in that slot you could use that but if the item changes you will disconnect.
