So I have these Holy Sword +1's and the added effect of holy dmg has never triggered. I have a Flame Sword earlier that did trigger. Perhaps there is a reason these don't work, like out of era, but if not then a fix would be nice.

Probably not coded. You can make a bug report and see if nas will fix it but it's not likely.

This. ^

There are a few other pieces with special effects that don't work either. No list either. If I buy something new, I usually ask LS if the special effect works or not before I buy. Most do work though. Pretty sure Rune Weapons are borked so steer away from those also.

Perhaps make a ticket about rune weapons? I bet nas would be willing to fix those since some of them are really good at level 75 IE: Rune CHopper

edit: I would but I have 5 tickets open pertaining to other bugs. (Real bugs, not stupid someone stole my HNM bugs)
