Go for the Divnity Anthology version (Dragon Knight Saga with add-on Flames of Vengeance included)
I play DKS on Xbox (and the difficulty on pc is the same I believe - but the very first version on Xbox, "Ego Draconis" was more hardcore, also on pc I believe):
1. play nightmare mode - 2. START with wearing nothing but pants and no weapons, onlty a Fireball to shoot or use Unarmed combat to defense myself ! 3. do not upgrade my hero with the best gear I can get as soon as possible via buying or whatever , only buy Yewellery with a Skill on I really want to use - 4. never reload for better loot - 5. honestly I must admit it's for sure not my first play/build in DKS, but it's now the most fun build to play with and more easy than I expected ! 6. ALL gear I don't love to see my female hero wearing I sell back, even if that piece is more powerful.
My build ?
For ME the most easy-to-survive-build AND at the same time the most funny one:
A Battle Mage Priest !! O boys & girls, it's amazing addictive to play !!
Stats I try now: put first points on vitality & spirit & intelligence and just a few in dexterity/strength (just for fun). Now my hero is Level 14 and invested points so her stats are (without boosts): vit 19, Spirit 17, Intelligence 21, dex 3 and str 5.
Skills? (3 points left at the moment)
Priest skills : Summon Mastery L2, Summon Ghost L5, Summon Undead (via a Neclklage SU+1), Charm L2, Hide in Shadows (Amulet +1), Blind L1.
Mage Skills: Fireball L1 (started as a Mage), Mana Efficiency L2, Magic Blast +1 (via Bracelet or Amulet).
Other skills: Lockpick L3, Two-Handed Expertice L2, Rush Attack (via Amulet or Earrings +1 or +2 both together wearing), Potion Efficiency +2(via Bracelet, loot reward for killing Penumbra), Confusion +1 (Ring as quest reward), Poison Arrows +1 (via Earrings), Splitting Arrows +1 (via Earrings) ...
Later on I sell some yewelley back for other boosts to a sertain skill I want, like Thousand Strikes is so amazing to look at, or Firewall or .... so many ...
The very good thing with a skillpoint on (especially yewellery) gear is that you don't have to invest a point in a skill to TRY it out and see if you like it ! If not, just seel back and go for another one
...
Each battle I summon the Undead first, then the Ghost to heal me and drink potions if needed.
At level 13 I solved a quest to have now a Creature at my side (it can earlier on if you wish).
Then I go to Charm an enemy I wish (focus on and switch focus if needed) and then I Blind one. Some enemies can resist Charm, Blind or other such skills ... but mostly, try a second time if the first time didn't successed when you "don't see a message" that tells you the enemy resist your skill !
Then I mostly rush attack and with a two-handed flamberge (sword) I start slashing, my ghost do the rest : healing me if needed ! And if someone darf to attack my Ghost I rush attack to him/her and defend my Ghost !
Or I start the battle shooting with a bow, I've Rothman's bow, also as a quest reward.
Have many awesome moments in the Dragon Knight Saga !
