Custom Effect (and Resistance on ItemDB)

[OscarScorp]

Good day,
I'm looking for help on creating a custom status effect, such as a new Poison status and to add Resistance on item_db.txt such as:

bonus2 bResEff,Eff_Venom,1000;

I already have added the Status on files such as status.h, status.c, even on skill.cpp which where is triggered and it works just fine.

I also added on scripts_constants.h:

export_constant2("Eff_Burning",SC_BURNING);
export_constant2("Eff_Crystalize",SC_CRYSTALIZE);
export_constant2("Eff_Ignite",SC_VENOM); //Here's the new status

And on status.h:

SC_BLIND,
SC_BLEEDING,
SC_DPOISON, //10
SC_VENOM, //11 Here's the new status.
SC_COMMON_MAX = 11, // end. Original: 10

Problem is, if I want to add an equipment such as a Helmet which grants resistance to this new custom effect, it appears it does not grants the resistance on the item, even if I increased it to bonus2 bResEff,Eff_Venom,10000; which should make it 100% resitant, right?

Any help will be appreciated.
