[Urgent] Help adding customs to 2014 client?

[Aeromesi]

I stopped Ragnarok back when Xray was on its last stand when renewal came out.

I have the client 

2014-10-22b
I have max viewID set to 3000 or something with NEMO's patcher, idk if it's safe to set it higher? But that's not the question.

Does anyone have a guide that is complete on how to setup custom items in the latest clients?

Bump. I used the search function on the Hercules forum and couldn't find anything ><
