I think it was "~misfit~" <misfit61nz@woohoo.com.au> that wrote
something like...

There are no builds.  You just learn every spell you can.  To do so,
you need high int, so the gear you get should reflect that, though you
can have a 2nd set of gear just for learning the higher ranks of the
spells.  The spell I usually used was fireball.  chainlightning for
the fire immunes and teleport is ever so useful.  That's mostly it as
far as I can remember.  It's been many a year since I've played it.

I don't remember of any guides for D1, except for Jariff's guide.
and there are no builds in D1.  Just max every skill and keep
looking for equipment to enhance your build.  IIRC, my sorc
used FB as a main attack and what ever the ice one was for
the fire immunes.  And since you're playing Hellfire, I take it that
you're playing off-line.  So remember you can store stuff on
the ground when you quit.  And of course you can use the
Hell Stone(?) to move items from one char to another.
It's been years since I've played D1/Hellfire, but that's what
I remember.  Not bad for an old man.  <BG>

You only get to hotkey four spells, so I used to go with fireball, chain
ligbhtning (but be careful in multiplayer, as friendly fire is a big
problem), and teleport for three of them , then usually turn to stone
(can't remember exact spell name), but it would depend on what level I
was on, as sometimes holy bolt was a better choice, and usually firewall
to do in the big red cheese from around a corner at the end.

Avoid that random tele spell like the plague--it was suicide. Watch out
for the yellow zombies that permanently lower maximum life.

Get a Civerb's truncheon for dealing with triple immunes in hell
difficulty.

That's most of what I remember. I still sometimes play this on
battle.net, where I am still -Tymme-.

Mark.
