I just got done playing Icewind Dale and its expansion and it made me feel like finally doing a 2nd playthrough of BG2 (I only did 1 playthrough of BG2 4-5 years ago with my main being a Sorcerer imported after clearing BG1 and a full party with the in-game characters you can find).
When Siege of Dragonspear came out, I did a BG1 into SoD playthrough with a Darkmoon Monk having in mind to try to solo the entire series with him (I picked up a party when it was needed for BG1 since Monks start out super weak and I didn't want to take forever, I can't remember for SoD if I soloed it or had party members, I think I had a party but maybe not until the end).
My reasoning was mostly because I normally have parties built around a Sorcerer (which is my favorite class overall as it can do a lot of things and there's always some new spells to look forward to even when leveling late game) but I still like fighters. I sometimes got annoyed at how much time I had to spend buffing my entire parties before large fights. The monk seemed to start out super weak (mostly weak through the entire BG1) but the bonuses and scaling for high level into BG2 looked very impressive in theory.
Now, I can't remember all of BG2 and I don't remember too many fights being overly difficult with a full party on Core Rules except for the final ToB boss. I know that I beat it but I think that it did give me a hard time still.
Aside from this boss, I'm also wondering if there are monsters that a Solo Monk will not be able to damage with his fists because they wouldn't be considered high enough in + magic dmg weapon (I don't feel like having to use weird gimmicks unless it's very rarely needed).
I'm wondering if I start back a full playthrough from BG1 into SoD into BG2 or if I continue with this monk I had that just cleared BG1+SoD. I just don't want to realize that he's not going to make it once I'm halfway into BG2. I read some people saying that he can't use the amulet to protect from level drain so vampires are a big issue?
