I seem to be unclear in what I post. Yes the +10
Frost and
Shadow (like the 2 I linked before)
do work. I do not think it matters whom the armory belongs to (but as this seems important to you, both linked chars are mine), it is merely to prove to you that +10 Shadow Resistance to head give +10 Shadow Resistance extra to your stats. I have played this rogue in wsg
after Cata (small amount) and yes it
does still work. I do not feel like posting an ss, if you don't believe me that's fine. The one you linked does
not work (as I have stated a few times if you read my posts). As a clear answer to you question, yes
I have a
working enchant. (You can of course check my armry and look under "resistances", it says +32 for SR)
I allso posted not being sure if you can put them on BoA head (as I do not have a headpiece to try it out on) as the old way of putting them on BoE greens (head or legs to be precise) no longer work. I did mine a long time ago and as I have no BoA headpiece I have not tried it out for some time (ruined 2 trying it on BoE pants after the fix though, became soulbound).
+20 spirit to weapons was meant to give a subtle hint this rogue is old thus putting the head enchant in a time frame (without needing to elaborate like am doing now), yes it
did have it's use (stealth regen).
To summerize:
Shadow Guard - Item - World of Warcraft and
Shadow Guard - Item - World of Warcraft are the
only 2 head enchants left to
still work. Mialo has provided us with the information that they can/could be put on BoA heads as long as you kept the guards from before they where taken from the game (no confirmation if they still can be put on unless Lathoriel put them on very recently?).
Hope all is clear now.
