So, I know the series is HARD, and you're expected to reload and try again unless you go for some very specific strategy that you already know it will work. But even considering that, I feel I'm terrible, and it's really frustrating because at this point I'm pretty sure there are things I'm not seeing.
To be more specific: right now I'm playing ToB for the first time, and I can't beat Ravager at all. And I don't think the problem is in my strategy once in combat, but maybe everything else, such as party composition, equipment and prepared spells.
My part consists of Mazzy (27), Minsc (24), Aerie (19), Neera (23), Imoen (23) and Charname (24, conjurer mage.) So, my first guess is that there simply isn't enough damage. During the fight, my main source of damage is Minsc, hitting only with gram the sword of grief +5 and while in berserk. My casters are mostly useless, except for Aerie. Everyone else might be able to dispel the boss and debuff him a bit, but fail most of the times. They can't do much more than that, since they miss.
In fact, missing and having low damage seem to be my two main issues. Notice I've never used a million traps to kill a boss (in fact, I've never used them) but it's not like I don't know some general tactics to play the game. The thing is, they don't work - my battles go for too long and I don't deal enough damage. Balthazar killed me like 10 times, and when I got him, I didn't even know how it happened.
I'm playing in core rules difficulty by the way.
Any suggestions, or ideas of what I'm doing wrong?
