I'm just going over a few things.. if you get into this game and don't build your character correctly, you will not survive. I lessened the number of playthroughs from 6 to 4 from the original roadmap; 3 will consist of Silver, Gold and Platin (you do not need to playthrough Niob difficulty, just start it), and 1 (preferably Bronze) for a light or dark campaign.
The original guide points a lot of links to the Wiki for Sacred 2; it no longer exists on the internet.
I highly recommend the Shadow Warrior; he was a born tank. Just make sure you build him correctly. The following link has great examples of builds from the PC.
There are multiple great builds that will help you succeed in total destruction of everything in front of you. I personally went with this build and it's worked wonders so far.
I had originally started a Shadow Warrior on the light campaign not knowing what the hell I was doing with the build.. and it showed immediately when I was fighting bosses and graduated to gold. It was grinding and hard. So I restarted an entirely knew Shadow Warrior on the dark campaign with the above build.
Obviously you can choose whatever you want.. the following link has all the builds for each race.
Choose whatever you want, use a build from the DarkMatters site and run through a campaign on Bronze difficulty on whatever light or dark affiliation you did not choose for your main character. You can run through a campaign in 10 to 12 hours.
Since I had screwed up my original Shadow Warrior, I went with Shadow Warrior again. With my previous knowledge of the game, and a proper build I knocked out Scrooge, Dedicated, Survivalist, Ancaria's Dark Lord achievements.
Scrooge: Don't buy anything during the campaign. Utilize the Hero chest (it is located in most towns, chest icon on the mini map) and put weapons, armor and most importantly, healing potions.
Dedicated: Discover less than 20% of the map. (this must be a new playthrough) If you follow the roads, don't venture out too much and skip basically all the sidequests; you should finish the campaign at about 17% discovered. In the larger Orc, Swamp and Desert regions just cut a straight path from one quest point to another. All other areas, use the roads and backtrack when you can.
Survivalist: Don't die during the campaign. With the help of a couple hundred stocked healing potions, and on Bronze difficulty, this should not be a problem. If you do die, dashboard immediately, you can check your stats in the 'overview' tab, it will display your deaths there.
Ascaron Fan Achievement
Follow this link as it has a perfect walkthrough of the entire quest, including (if you want to get the goodies) an interactive map to help you track your progress.
If you find all 98 of the 'employees' and get the 2 rings you will unlock Fashion Police.
Unfortunately a lot of the links on this site were linked to the Wiki, and that Wiki no longer exists. You can find some info scattered here and there; but a majority of it is gone.
For the Shadow Warrior the easiest set to acquire is the "Infernal Torment" set; all it requires is the chest, shoulders and helm pieces.
This site has a bunch of maps, for most of your needs.
Also this one on the original achievement guide.
So take whatever character you're going to build and start on Silver. Take your time with this playthrough and depending if you chose light or dark you should spend about 30-40 hours on this play. You will be getting all the story related achievements, level achievements for that character, whatever light or dark achievement at the end and a few other random ones. Explore 50% of the map and complete 200 sidequests for those respective achievements; during your exploration find all the towns and Houses of the Gods.
Once you've completed all that, start a gold campaign. The Gold achievement will unlock once you start the game. Run through gold as fast as you can building your character to spec. Once you finish gold, you will unlock Platin.
Same thing with Platin difficulty, get through it as fast as possible. Once you complete Platin, the Niob difficulty will unlock. For the Niob achievement all you have to do is start the campaign, you don't have to play through it.
For the 4th and final full playthrough, choose a secondary character and run through Bronze, discover less than 20% of the map, don't die, don't buy anything from the merchants. I finished my bronze playthrough having discovered only 17% of the map.. backtrack when you can and make straight lines when you can. You can only really make straight lines in the swamp, orc, and desert areas.. for most other places.. use the roads.
For your light and dark campaigns choose the same style of character (this is why I went with the shadow warrior). From my first (messed up) SW, i saved some of his lower level equipment and put it in the 'hero's chest' which any character can access. Stock up on health potions and store some in there periodically. This is a huge benefit, so take advantage of it.
Also, for all your subsequent playthroughs, if you save a lower level weapon with some smithing slots on it, you can take it to a smith on your main character.. the +'s to whatever stat will be much better and will make a lower level weapon god like.
