Do terror zones have increased treasure class?

Does anyone know if a

Terror zone has an improved treasure class also? As some of you may know, Diablo 2 uses a very confusing system where what items a slain monster can drop is dependent on the monster's level AND the monster's treasure class level. If

Terror zones do not increase the treasure class of the terrorized monsters, then they're not very good for farming. For example Act 1 Hell

Fallen in the

Cold Plains will NEVER be able to drop a

Griffon's Eye even if it's level 6000000, if its treasure class is not ALSO increased.

Oh and yes, by the way, of course I've been watching on the few

Terror zones I've had time to run, but the problem is every time I've logged on so far the

Terror zone has been like

Arreat Plateau where a difference between the default TC and a boosted TC would be hard to notice.

I found a

Sacred Armor in

The Den of Evil.
So yes, TC are in line with TZ aLVL and the resulting monsters' mLVLs.

I think the very special thing about the zones is that the area lvl seems to also be affected. I dont think thats the case in the 85 Zones like The Pit. TC87 Stuff may drop from chests and other environment. A

Sacred Armor dropped for me from an Armor Stash with a lvl 95 champion as creator, i think in jail, thats as far as i can confirm

I got

Tyrael's Might from a random

Skeleton in a terrorized (96)

Tal Rasha's Tomb.
