I have been enjoying my cleric/thief for all the utility that it brings to the table. I use it as a sanctuary abusing trap finder/disabler, lock opener, dead turning, healing, buffing, trap laying, support character. I am considering making a Swashbuckler->Cleric Dual-Class and wondered if it would be worth my efforts. I would level it up in a solo/easy mode run and then use it on a heart of fury playthrough duo with a Fighter/Mage after it is a full swash/cleric. So I don't mind if it is tedious to level it up. I am thinking that I would end with 25 Swash/26+ Cleric.
The advantages of being a swashbuckler->cleric seem really nice on paper, however, I am wondering if there is anything I am not considering that would make the cleric/thief multi-class a better choice?
The way I see it, this is everything to be gained by dual-class Swash->Cleric:
1. Increased Weapon Specialization (2x limited to clubs/quarterstaff/sling).
2. Increased Positional Specialization (3x for Two Weapons Fighting Style).
3. AC/Hit/Damage Increase (+6 at level 25 Swashbuckler).
This is everything that I would lose by this option (compared to thief/cleric):
1. Backstab (meh I never do it anyways)
2. Level 30 Thief (does that matter too much in IWD?)
3. Some HP, d6 instead of d7* (*this is the average of both classes right?).
4. Race Choice; I prefer non-humans, so this is the biggest downside to me.
5. Roughly five hours to speed run IWD once or twice on easy mode.
Is there any benefit or drawback that I am not considering or is there something that would be a better choice for this combination? Shadowdancer seemed like a feasible option as well, where I could straight up shadow step away and then sanctuary my way to healing safely.
Any thoughts or suggestions?
