Some effects (those that rely on protection from specific spell as pointed by its resource name) could be game-specific - I've been modding a lot, I might have hooked up protection not from vanilla spell but a mod-created version. I did the hard work of figuring out which effects to hook up. If you find you want most but not all of the effects I put there you could try to edit it yourself - NearInfinity is mostly simple tool, and it doesn't take a genius to figure out, for instance, which effect is responsible for AC bonus you don't want and delete that while keeping everything else.

Miight also protect from time stop, not sure if I got that working eventually, I was still messing with it before I stopped playing. I might have hooked up Shield of Balduran protection from Behloders to it as well, not sure. Oh, and level drain, that too was no fun for me. It has an assortment of random bonuses I deemed useful at one point (THACO/AC/Saving throw etc), some elemental resistances (possibly all of them not sure), permanent improved haste (that stacks with boots that improve movement speed to really zoom across the map), but most imporantly - protection against every spell in the game that impaires movement, stuns or in some other way takes away control from your character (including imprisonment), as well as any instakill effect (petrification and anything Death Ward protects from). It is a new item, you will need console command or save editor to get it in your inventory (I could do that to exsting helm or any other item, used to do that a while ago, but then you meet somewhere in the game person wearing it and they get all the benefits). Oh, since the topic came back alive, maybe people here might be interested: any time I play I like to give my party my helm of awesomeness.
