Diablo 1 Lazarus' Lair

[Ham]

Not related much to the topic, however I can't seem to
start a new one, so a few questions to the community:

I've recently returned to play Diablo I, and after a
couple of weeks I started doing Lazarus runs on Hell
difficulty to get some cool items. I managed to find a lot
of great stuff, however no Naj's Light Plate drops. I am
not sure how many runs I did, but I remember getting
items like Demonspike Coat and The Grandfather 20+
times already, and I've pretty much seen all the unique
armor drops a couple of times, but not the Naj's Light
Plate. So the question would be if there some known issue
with its droprate, or just a bit of bad luck on this side?
Maybe there is a better place to farm for this drop?

Also does anyone know a mod which enables you to check
all the stuff that is on the ground? (Similar to what the key
"alt" does in Diablo II)

Finally, a question that people won't like, but I'd be interested
in this one: Is it considered a big cheat if I change the skin
of an item I acquired legitly? (I want to change the armor type
of the Naj's Light plate [if it ever drops] to Mail armor, because
I like the Mail skin on Sorceror much more than the Plate one.
It's basically just a graphics modification).

Thanks in advance for the replies!
