deamento: 1) i am indeed unfamiliar (if we're being generous) with the d&d rules. i am now well aware that i build my characters wrong, the way i build my characters is always focused on dialogue etc. and not combat. to be honest i have no clue why i do that.
This can be an example of when having a role you want to play might be helpful. Try to think, what would a smooth talker do in the current situation? If you're going to use dialogue stats and perks, always try to take the dialogue choices that will avoid combat. Don't worry about trying to collect every little thing. If there's a treasure chest guarded by big burly ogres, leave it be unless an ogre wants to talk to you and barter for it.
What else could a character built for dialogue do? Well, a character could hire a brute to do the dirty work for them and if you're in charge of leveling up that brute, make sure to choose combat stats and perks/feats. If you don't have a brute companion/party member, find one and return later if you really need to know what's in that chest. You could also be stealthy to try to avoid conflicts. Don't be tempted to do a critical hit backstab if you can't finish the fight!
deamento: i got it wrong, i MIGHT enjoy the combat but i can't because i don't understand the mechanics of DnD
Some of the D&D games allow you to turn on rolls in the scroll thingy (I can't remember the proper name for it right now). It should be located in the Options somewhere to turn on or off. If you really want to learn how stats and rolls work in those games, this can be helpful. Temple of Elemental Evil does a very good job in this regard, as well as the help and descriptions of items when you hover over them with the mouse pointer or when you right-click items and stats and spells.
ToEE is also turn-based so you can take your time trying to figure it out. It's also very heavily focused on stats and combat and implementing the rules properly so if that scares you, this game will scare the shit out of you. Combat can be pretty tough but can be rewarding too. If your main focus is narrative, ToEE might not be the game for you, but if you want to learn how stats work in these kinds of games, it can be a great way to learn. It will either break you or make you as far as figuring out if you truly do like this kind of combat or not. Sink or swim :)
