*facepalms*<br/><br/>I forgot the 1 CL requirement for the PrC! My bad! Well, you could go swashbuckler/bard (or sorc) and then level dip dragonmark heir and then enter storm sentry if possible and then windwright captain.<br/><br/>So kind of swashbuckler 3/bard or sorc 2/dragonmark heir 1/storm sentry 1/windwright captain 1. Complex class levels wise but fairly simple. Sorc would allow get electricity spells (while bard gives good skills, better saves and ofc inspire courage feature). But Vandros is marshal and so he can provide all party buffs needed (changed one minor auras to motivate intelligence so he can competently roll knowledge rolls and do amazing crafting rolls).<br/><br/>Also for added spell-alike ability flair you could get arcane stunt variant of swashbuckler to get some nifty spell-alike ability uses. Although build wise you would depend Dex, Int and Cha (all three attributes good for swashbuckler but also depends on sorc and dragonmark stuff).
