Fjord Cutter: It doesn't really hurt stuff, I think; it only chills (and occasionally freezes). The only use for this is, to my knowledge, on a support barb to keep up the Iceblink gem for a group; but there are better cube powers and better ways to get chill effects, so it's not really something you should cube.
Leoric's Crown: It simply takes the helmet gem and doubles its effect, no matter if you wear Leoric's Crown or have it in cube. Just forget about the orange text (which obviously can be misleading in that case).
Arcstone is useless. So is Shard of Hate. There's many much better rings+weapons.
Yes, Nemesis Bracers are very good, especially if you're using In-Geom they're basically a must-have.
Someone made a list of all useful cube powers a while ago, check this out (it's a bit older but should still be up-to-date):
I'm looking for useful powers that aren't obvious.
Advice, so I don't actually have to sacrifice items just to see if it has a practical use.
Example;
Has anyone done the Fjord cutter?
Does the "chilling aura" actually hurt stuff?
Also, Leorics crown. The game keeps it in the possible list, but how can a power completely dependant on what you socket work as a general power?
Arcstone. I assume you still have to put a second one on your follower for this to work, you just don't have to wear one yourself?
As far as the ones I use most, shard of hate is a must for any cold or lightning based farmer build.
Nemesis bracers, unless your actually wearing them, help speed up rifts by multiplying how often you see minibosses.
Anyone that can help with the above questions, and maybe add a few others that really help out that arent listed, thank you a ton.

If you're not sure about an item's usefulness, look in the build tool how many builds there are with said item, that should give you an idea:

Thanks for the info man.
I appreciate the very good responce. I also wasn't aware you could search the builds like that with specifics, very cool to know.
