hey hermit boy, that sounds like a fun one. good luck to you.
regarding the bard, you'll find that early on their stamina is a problem. but later, they'll have more (just from levelling up), and your spellcasters will gain access to the stamina spell, which can recharge them easily (not to mention the plethora of potions you'll eventually stock up on!)
if you had made the bard female, there are a number of items that regen stamina more quickly, but they are for females only - perhaps something to keep in mind for your next group
in the meantime, if you want to build up your bard's internal reserves, there are 3 stats that contribute to stamina: strength, piety, and vitality. bards can make admirable front line bashers, so many people choose to build strength. however, if your bard is mostly throwing from the back, you might choose vitality instead.
