[Mod Request/Help] Trying to do an Item with passive Reduce status

[Eliogabalo]

Hi! I'm currently trying to make an item with a permanent reduce passive status, the problem is that I don't really understand the status names, parameters, and the linked variables to the passives different variables, and I don't know where to start.

I tried to look for a REDUCE reference in the gustavdev folder but the only reference I could find was in the Spell_Target.txt file

 

 

I've been trying to come up with something by looking at the other passive elements structure and I've came up with this,

 

(ignore the name it's just a placeholder)

 

but still I don't know if this effect is going to last only a few turns, if on equip my character will do a saving throw or something like that. Or if I need the check another file to be sure if it's going to work. Thanks in advance.
