It is very interesting that this is without a program.
I've been dealing with many methods for days with the cheat engine.

transactions I have tried;
I changed the epaulette slot numbers.
epaulette level changed.
I tried plugging many items into epaulette slots.(Such as weapon, armor, accessory etc.)
methods like this but the server did not allow it.
The general logic of stacking is to render something unusable on the slot and somehow slide it to the slot old tricks show this.the method mentioned could not make any logic. For this I doubt your truth
