My interest was piqued in browsing another thread, which I did not want to derail, so asking anew here. How do you get the most out of an F/M/T? (and please, no spoilers on progress through SoD as that is still not available on my platform - assume BGEE goes straight into SoA)
My naive approach ends up treating them as essentially an underleveled FM, that will not hit level 9 spells by the end of the saga. That seems sub-optimal.
The main motivation I have for playing this combo is that for the longest time, you are going to be scoring more levels than anyone else - as the xp curve takes a long time to flatten out, so you are effectively 2-3x as long in the sweet spot scoring frequent levels, paid for by taking so long to hit the first of those levels (even the party mage is well on their way to 3rd before you hit your first bump). The major downside is that after that xp curve levels off, you are condemned to simply falling further and further behind the rest of the party - so better have found your synergy by now, to make the most of it.
So how do I add effective thieving into my mix? I level slowly, and will have few points to spread around in the first game, but can I sufficiently take the mantle of party thief for SoA/ToB by focusing points well (at the expense of combat) so that no other thief is needed?
Should I focus on stealth, and play as a F/T with occasional magic assistance? With low mage levels in the first game, that might make sense, but likely inhibits transitioning into sole party thief for SoA?
Thinking of my PC as an MT with more hit points and improved hit rolls does not seem productive to me, and mostly the fighter does not bring interesting equipment to the table, as armor interferes with spells and thievery.
It is tempting to highlight solo play, as a one man party, shooting through those levels as fast as possible. However, solo always seems to be missing the point of the game to me (my perspective) and there is no trouble hitting the level cap in BGEE. A reduced party might help hit the level cap in ToB, but I do like finding NPCs to hold onto all the cool loot we find throughout the campaign.
Is there some sweet-spot interaction of the 3 classes that I am missing, or does this class actually play as an underpowered alternative to any of the 3 duals?
And for advanced students
. does the FMC play any better or worse than the FMT?
