Does lower resist (Necro Curse) Break immunites?

[Obi2Kenobi]

Also note that if you break an immunity, the resistance would still be very high. For example, if you used the slvl 20 LR on a 100% resistant monster, it'd end up with 88% resistance, which is still a lot.

Unless coupled with another item that reduces enemy poison resistance, such as a Rainbow Facet.

/edit: Or conviction... but that requires a partner Paladin.
