Raze_Larian: Playing a ranger in DKS on nightmare difficulty, I stopped distributing any stat points after level 15.
The first part of the game is relatively straightforward with only a couple skills (I used Poison Arrows and Stun Arrows in addition to normal arrows) and few ranged opponents. The types of opponents and the terrain do make ranged combat a little more varied later in the game. I still primarily used two special skills, though: Explosive Arrows (which is inherently fun to use for awhile after you get it) and Splitting Arrows (great at close range - either melee opponents that get close to you, or you get close to a boss type opponent - and good for groups at medium range). Late in the game (level 40) I started using Way of the Ranger, which boosts the damage of normal and splitting arrows; you could try that if you think a faster combat pace would help, or avoid it if you want more of a challenge.
Are you still inclined to remain an archer? You could try unarmed combat, or something (you can redistribute your skill points after you take over the battle tower, at a character level in the late teens to early twenties).
Nah, I don't care about staying as a ranger. Thanks for the advice, I will try unarmed. It's pretty ridiculous that I have to handicap myself to make combat more interesting, but whatever :P
Thanks again.
