So I've gotten it into my head, with the hugely powerful potential of swashbuckling, and it basically replacing my unarmed monk builds since having to invest 16 levels into a single class and gimp damage is unfair on the instakill side of things, but 6 levels of a splash class for it is just fine, that I want to try an Int based SB build. I was looking at all the different potential, and decided that I'll save my fighter/barb based builds for my current main who is already mastering the dwarven art of being fat with con and hand axes. That left me wondering how to abuse the stat to damage change enhancement for SB, with the three stats being DEX, INT, CHA. I've never been a huge fan of DEX builds, and with AC not being as powerful as it used to be STR is just plain better since you can get Overwhelming Crit without taxing your stats into submission. Leaving INT and CHA, INT offering more skill points and caster splash options, CHA offering high DC for Bard abilities and potential with Turning/Sorc splash.
Between the stats the easiest to get to hit and damage with would be INT, since artificers can get Insightful Strikes at level 3 and not be restricted by weapon choice, a huge plus. The obvious pairing with this would be wizard for the EK tree and several nice caster options. So bard gives you Swashbuckling, Wizard gives you a wide range of spells and buffs as well as inscription for a fair amount of flexibility, Art gives you nominal perks related to scolls and wands as well as insightful strikes. Overall giving you that nice jack of all trades, easy meta magic feats, but taxing on the melee feats. DC's won't be superb, and you won't be the best at defense or offense.
So the question is, would such a split really be worth it, what race gives you the best potential, and which level split fits together without crippling the build. 6 bard gives you full access to th SB tier 5, 10 bard gives you 4th level spells, 3 art for trap skills and IS, 7/9/11 for 4th/5th/6th level wizard spells respectively. I haven't had much dealing with the Wizard class so anyone with knowledge of how useful the EK tree with SWF/SB would work endgame and the potential benefits of the wizard splash would be appreciated. I feel like even if this split might not work well past 20, it might be a good TR jumper, allowing nice progression from 1-20 without too much requirement. Though art is a premium class.
