I was away for a week and have been reading many articles and posts about Dual Classes. Through my many playthroughs (BG1/SoD/BG2/IWD), I never experienced much with Dual. I only did a Kensai 7/Mage solo BG1 if I remember well and tried it early BG2 before deciding on a different main character. Other than that, I've had something like Anomen Fighter 7/Cleric, Imoen Thief/Mage but I think those were forced on me in BG2, I can't remember too well.
So I know how the basics work with the downtime, the stats requirements, needing to be human, etc.
What I'm unsure about (doesn't help that some of the articles and posts I've read are about vanilla BG2 and some others are about EE, I'm personally using EE right now) are the possible combinations and how it affects weapon proficiencies.
I really hated the downtime of the Dual Class vs Multi (on top of being forced to be human which meant no half-orc higher str and con for example and so on). I'm currently getting close to completing my BG1 playthrough with 5 premade characters + Dorn. One of them is a Cleric/Thief mostly because I wanted to be able to disarm traps and unlock everything (I loved my F/T on my previous BG2 playthrough for backstabs and traps but I'm using a Stalker this time around in my party so I mostly wanted Thief skills for utility) but I didn't want the downtime during BG1 for heals or traps so I went with Multi. I was thinking of switching this character for a Dual once I hit BG2 (I plan on doing BG1/SoD/BG2/ToB with the same party). I wanted a stronger cleric rather than a weak cleric that has many points into thieving stuff that I don't really plan on using (however, I'm using SCS for the first time and I read that detect invisibility is very useful with this mod so I might change my mind and try those strong staff backstabs at the same time but my cleric spells will be quite limited).
Aside from just grabbing a 1st class to unlock utility and pushing the other one higher in levels, the main thing that grabbed my attention for Dual Class over Multi is the fact that I could use some Kits (which could add extra flavor or yield slightly different characters).
So here are the things that are unclear to me:
1- I think that I understood that I can start with a Kit and then Dual into a general class (F/M/T/C) but cannot get 2 kits or start say with Thief and then add a Kitted Cleric as Dual (which was what I wanted to do with my C/T Multi once I was going to hit BG2)?
2- Are there some kits that aren't available for Dual class? I think that I read Paladin, Bard and Shaman are unavailable but the rest can work (and Druid can only be used with Fighter)?
3- What are some of the better Dual Class kit options that might have an edge over their Multi counterparts? I know many talk about the Kensai/Mage or Berserker/Mage. Kensai/Thief (seems interesting), Wizard Slayer/Thief (I wish I thought about that one during my last BG2 run with my Wizard Slayer although I would have lost the Half Orc and lost some magic resistance from the extra levels once it's finally starting to kick in). Anything else? I'm curious about the possibly Druid Kit combinations (I liked my Shapeshifter I made in IWD but the Werewolf and Greater Werewolf THAC0s were horrible and it could barely ever land a hit, wondering if Shapeshifter/Fighter could make the werewolf forms more effective or if the downtime is just going to be too long).
4- Fighter/Mage combinations, many people claim it is the strongest possible character type but to be honest, if you dual at say level 9 (which many suggest over lvl 7 or 13), your melee THAC0 is going to be very weak compared to a pure fighter and your spellcasting will also obviously be quite inferior to a pure caster. I fail to understand how this class can be remotely good in melee with such weak THAC0. Sure you'll have a mage that has an improved THAC0 and more hp but mages can have so many good defensive spells, I feel like the extra hp might not matter much in the long run. Is it all about Tenser's Transformation to make up for the weaker THAC0 and melee damage? If you end up being a weak melee in the long run, I don't understand why go through downtime and all of this just to end up with a gimped mage in the long run.
5- Weapon proficiencies. I'm confused about this one. If I go with Fighter as one of the two classes, does this mean that I would be able to use any weapon type once both classes are active? For instance, would it allow a Cleric to use swords?
