You've musunderstood Tricky, he's talking about Numbul, the assassin who you meet in Nashjel after the mines, not Mulahey.
How you managed to rescue Dynaheir, clear the mine but still be only 2nd level baffles me, how on earth did you accomplish that?
You get slightly lower xp with less difficulty setting, but maybe not much just 80%. I went almost straight to minsc and then straight to the gnolls. I got the boots of stealth somewhere. I killed the heckler at the Feldpost Inn. Oh and definitely killed noober despite being not much xp
First thing Minsc should do is go berserk, that way horror won't affect him.
Brilliant idea.
The biggest problem you had was being far too low level at that point; I'm still trying to figure out how that was possible. I can only assume you went at it like a bull at a gate, ignoring everything between you and Dynaheir then Nashkel mines. If you'd explored every area you went through, the area beyond Candlekeep (did you find the +1 ring and the Ogre with the belts?),
Got the belts no ring. I did get a ring of infravision and a holy ring somewhere.
At the Friendly Arm in (did you find the hidden ring outside the walls and complete the quest to find the flamedance ring?)
Didn't get the flamedance quest and couldn't find the ring, looked at all of the trees it seemed. I might look at the x/y coordinates later (and the ankheg coordinates too).
Beregost (did you get Algernon's cloak, if so first thing to do with Nimbul is use the cloak on him), choosing the right dialogue options when entering Feldpost's Inn nets you 950XP alone. Did you complete the quest the dwarf in the Friendly Arm Inn gave you? Did you accept Garrick's offer of a job?
I think I did Garrick and I killed the heckler at the Inn. I didn't get Algernon's cloak, but I am leveling Imoen in pickpocket until dualclassing her. She's at 45% right now.
In the area below Beregost the first thing you should have run into was two half ogres, one had a note, did you read it and tell the intended recipient in Beregost? Did you find the Hobgoblin with a magical pair of boots?
Got the boots and the note but didn't find where to take the note. I was going fast because jaheira and khalid were complaining about Neshkhal and I wanted a multi-class divine caster and like I like Khalid for comic relief and for his archery and faster leveling chart.
In the next area south did you have a fight with a rogue Flaming Fist guard?
Oh I thought this was a real Flaming Fist guard and I didn't want a bounty. Probably should have reloaded options but I am making a VERY casual playthrough.
In Nashkel did you find the hidden armour? Did you get the mini quest to find Joseph (and did you find him and return the ring?). Did you meet the assassin in the Nashkel Inn?
Didn't find hidden armor, but I did return the ring and give the dagger.
After picking up Minsc and heading for the Gnoll Stroghaold you would have had to pass through at least two areas, encountering Xvarts, Ogres, half Ogres a polar bear plus others.
I didn't clear the areas because jaheira wanted me to go to neshkel and I figured 'might as well'. I just carved straight to the gnoll stronghold. Killed tons of gnolls and xvarts
Lots of Gnolls in the stronghold, did you find the manual in a cave outside the stronghold, and you did get the gauntlets of dexterity right?
Yes I got the tome of charisma and the gauntlets. I had imoen read the manual because in SToA I will have the ring of human influence.
Then the mines themselves, did you return the dagger?
Yes
I suspect the answer to a lot of the above question is no, they have to be no otherwise you'd have been at least 2nd level by the time you found Dynaheir. If the answer to most of them is yes, then I'm completely baffled, and can only assume there's something wrong with your game and you aren't getting anything like the full xp you should be getting.
I think it is a combination of: not knowing all the quests and not wanting to use a walkthrough, lower difficulty, going straight through. For example I picked up minsc at level 2 whereas a different attempted run I did clear maps and got minsc at level 3. Actually the other playthrough I only split xp by 4 and did Neshkel by just 4 person party. For some reason that party got a nice reload on Nimbul and he became afraid right away and we just wailed on him/her.
Thanks for all the suggestions, help, and consideration!
