Stuff: I think it may be possible, on easy, with
a good walk through. More likely to happen on your second play through rather than your first though.
The game took me around 60+ hrs to finish on my first play through where I became very aggressive as I learned to play the game (being cautious would have increased the game time considerably). That is a long time to go without getting killed at least once. I have played for hours without getting killed but . . . I've come upon something new that caused me to misjudge the situation and . . . I got killed. (Orcs morphed into Dwarfs will do that) DD is different in many ways from the basic hack and slash. You need to slow your game play (especially early in the game) and lure individuals from a pack rather than just attacking the pack. Having said that, there are certain kinds of critters you can just wade into the pack without hesitation (i.e. Skeletons coming at you in a single line, hold control and hack away). Learning the difference is mostly done by playing the game. Lure one critter, hack away, take potions if you have them and run away before you get killed. ALWAYS run back toward an area you have cleared as you will encounter more enemies running into unknown territory.
Even if you do get killed, the game reloads quickly. Save often and especially before any major conflict using the S key rather than the quick save as the quick save corrupted saves for me and others. I've had no corruptions using the S key for saving.
There are some critters that you might want to avoid . . coming back later to do them in. The first dungeon is the one most folks dislike the most it seems. I see it as a tutorial and a leveling opportunity, clear every room and destroy as many critters as possible. The game really opens up as you move out into the world. You lose nothing by avoiding some strong critters and can come back for them later but . . . you won't level up as quickly.
DD also differs in the fact that ANY character, male or female, can use any weapon or magic equally well. Some folks swear by the mage, some by the warrior and some by the Survivor. The truth is it doesn't really matter as every skill works the same for every character. The special skill is what determines my choice. I prefer the warrior simply because his "special skill" is more useful to me. When a warrior is invisible, he can cause damage with the special right-click skill and the victim cannot see him/her. If you left click, even once, you become visible and lose the advantage. Even if you make your warrior into a powerful mage it doesn't take long to get your magic skills increased and you get the benefit of not having to raise your strength right away.
I won't try to give you a build other than tell you my preferred build. I like to get my sword expertise to level five and my preferred magic skill expertise (Lightening) to level 5 as soon as possible. I use the sword for close work and Lightening as my ranged weapon. Having not specialized in crossbow I can't really comment. I prefer a sword with zero recoup time since I can deliver more cuts even though the damage is less. IMHO, it does more damage than a slow, high damage axe. True, the axe does more damage but . . . I take more damage myself from enemies while using a slow weapon. I find a particular sword about midway through the game and basically use it for the entire remainder of the game. Maybe some folks will give other input on builds . . . =).
My advice would be not to place too much value on "not getting killed" but to rather enjoy this great game, music and story. If you get killed . . . just reload (remember to save often) . . . =)
Thanks a lot for a great post! Of course I'll enjoy the game either way, but this "trying to win games on first try" playstyle is something I've really come to like, even though I never actually suceed. =)
When it comes to invisibility BTW, is it something that actually will work on monsters that matter, or can all important monsters see you anyway?
