1.10s weaponss: -x% to enemy elemental resistance:

[Nicator]

When I first saw weapons with those attributes I thought that the effect was triggered and lasted the effective hit by the weapon.

Some weeks ago, I made a Doom weapon for my strafazon's Act 2 mercenary (-57% to Enemy Cold Resistance), and since then I have noticed that when fighting a physical and lighting immune monster, coupled with magic resistant or spectral hit, my slvl 8 cold arrow made more damage than my slvl 12 fire arrow.

I haven't checked each of those monster's resistances, as they were from several classes. My best guess is that the -57% to Enemy Cold Resistance is triggered by an effective hit but lasts the chilling duration.
