Another Daggerheart but a bit different...

Broadsword is an Agility based weapon that considering your Trait distribution would get +0 on attack rolls. Also since the burden is 1-hand, you can equip a secondary weapon or off-hand(Shield) if you'd like. Since you have I am your Shield, you might benefit from a Round Shield(if not Tower for +2 Armor slots at the expense of 1 Evasion).

Rise Up is a level 6 Domain card. You can't have that at level 1. Had you done +2 into Strength(due to being the Spellcast Trait for Seraph), I might had recommended Bare Bones(Valor) because it gives you a Damage Threshold of 9/19(10/20 with level 1 bonus) and an Armor score of 3 + Strength(+2) = 5(and more with off-hand Shield). All it'd cost you is not having Armor and a Domain card slot.

You wouldn't tank damage as well as a Stalwart Guardian but another reason id recommend +2 Strength is because your Class Feature(Prayer Dice) is based on it. The higher your Strength, the more Dice you get per session to spend and they can be used as you see fit. Prayer dice, to me, is probably the strongest Class Feature in all of Daggerheart but that's just my opinion.

I like this, yes pls Hades!

I'll switch the domain card and edit it tommorrow morning.

1. No, feel free to go wild with Ancestry but I haven't looked to see what Expansion added.
2. Shooting guns is rather subjective. Ranger can fire arrows at multiple targets via Hope Feature, Spellcasters(Sorceress, Wizard, Druid and even Bard) can do so with Spells, and certain Martial classes can beat the snot out of people(Brawler Class in Expansion is basically a glorified Monk while Warrior, Guardian and Seraph can bash heads too).

I suppose there is the Blunderbuss(Tier 2 Finesse Weapon). Only class that uses Finesse for spells is Rogue(afaik, haven't looked at Expansion beyond Brawler, which has no Spellcast trait like Guardian and Warrior) but I'm not sure Rogue is to your liking. Rain of Blades is like shooting a gun I guess. *Shrugs*
