DS1 & LoA Gameplay Discussion (spoiler warning)

The Dungeon Siege History document on this site, "written by Lone Knight, spans the content from:

Dungeon Siege 1 (including the Utraean Peninsula map)

Yesterhaven

Dungeon Siege: Legends of Aranna

The bonus Quest to Legends of Aranna

Dungeon Siege 2

Dungeon Siege 2: Broken World

Dungeon Siege: Throne of Agony

They are all canonical works by GPG. Nothing else has been added."

Um..so..help? Ok, so Originally I got to this guy at level 35 with the level adjustment mod enabled (default included version). I was able to down his first form no issues. However, when he got to his second form, he summons 1 sekh and by the time that sekh is dead, whatever damage i did to him, is healed back to him. Considering I can't tell one guy to attack sekh and the other guys to attack gom (could use grasping vines and just ignore add i guess, but I still have to take the 1 second to target the guy, in which time gom regens his health a little).

Hello, I'm playing the Utraean Peninsula map with the DS2 Legendary mod. I'm in Hiroth Castle and on the upper floor there's a platform in the SW corner that leads down (presumably) to the sealed off room on the ground floor. However, I'm unable to use the platform. It says "You do not have a quest item required to use this lever". Any idea what that is? Am I supposed to find that in Hiroth Castle or in the mausoleum, or from a previous location (and I sold it)? Thx

I need an hair textures mod, if anyone has got such a mod I'd really like to get my grubby little mitts on it, I'll post a thankyou beforehand just in case someone has one or more of them.

I was wondering if someone could help me acquire the file of the Dungeon Siege: Legends of Aranna music / sound effect that plays when you pass the tomb of Orrin and Feline, heroes of Arhok, in the Zaurask stronghold - right before Neener’s Emporium.

Prologue

So after a move, I found out that I lost my LoA CD key. Thought for sure that is it was contained in the little CD slip/envelope thing, but turns out that it was actually in the user manual that comes with the box.
And, of course, the manual is what's missing. Typical.

Short of resorting to key-gens/pirating or buying a whole new game, how do I get a new key? Is there somewhere I contact to have them send me a replacement? Fat chance I know.. YEARS LATER after everything goes away, but this game was supported by Microsoft, right?
