I want resistance to freeze effect, not to damage.
If it helps someone with the same problem ...
I decided to add the "SC_ITEMSCRIPT" as this commit:
https://github.com/H...f0ba60c914d0f88
Now I can enter the command on my item:
sc_start SC_ITEMSCRIPT, 60000, 4105;
Executes the effect of Marc card during the time I set.
