High Elf mask requires mobs spawned from the rogue epic, so you have to have Kunark for that.

half elf from surefall, but I'm not sure when that one was put in.

There was also one from ssra, I forget which one that was. or maybe my memory is playing tricks on me, it's been a long time.

Water elemental for bard/ench in sirens.

Dorf mask is Luclin'ish, the ST revamp was quite late.

It was quite the deserted place after the warders bit the dust.

Both of those are post-velious.

Lute of the howler, werewolf, velious

Jaggedpine Forest, PoP-ish era.

Mask of the Hunter, Vah Shir illusion.

Meh, other than the dark elf mask they are all good or neutral races... in other words purely used for fun.

I guess for a barbarian they offer shrink but other then that I feel like I should have rolled a dark elf rogue.
