That one is not as accurate tho.
I made one thing for this, same as the item reader.
As for instructions on how to install, although Auli already gave you a viable option, I'd recommend to follow these steps, as it would give you latest versions for everything.
This for the framework-plugin thing: https://github.com/HybridEidolon/psobbaddonplugin#installation
This for the addons I have developed: https://github.com/Solybum/PSOBBMod-Addons#installation
My addons include player reader (Shifta, Deband and the likes), item reader (inventory bank and floor items, this one includes the mag timer stuff), and monster reader with monster HP, S/D or J/Z etc.
