What is the usage of chrmgr and RegisterEffect

[white 1]

Hello metin2devs, as the title says what is the usage of chrmgr and it's method Register Effect?

I did not find the class of chrmgr and I would like to know the usage of this line especially:

chrmgr.RegisterEffect(chrmgr.EFFECT_REFINED+19, "Bip01", "D:/ymir work/pc/common/effect/armor/armor-4-2-1.mse")

First of all I checked in the corresponding path and the armor-4-2-1.mse is missing however this does not make any error and the effect is applicable I mean since is on the binary.
