So. On group resource stuff: there’s no 100% standard thing; a lot of groups centralise stuff. If your group hand you potions and stuff you may well end up getting about as much back as you gave them. Not everyone does it that way, though. (And I tend to assume good faith on stuff so if everyone else is all “that’s really weird” maybe trust them. )
Resource choice: the classic Dawnish warrior pick is a military unit - very thematically appropriate, and if you don’t have a strong idea of what else you want, I think it beats all the other choices on those grounds.
Skills: think about what weapons you want to fight with. Shields are great, polearms are great, two-handers can do SHATTER which is great. Fighting with a weapon in each hand is… difficult, but if you can do it it can work.
This comes down to what kit you have available, really. You can just go with a one-handed weapon and buckler, but as a frontliner you might want one of the other things.
If you can get hold of a shield or polearm, that’s your first two points spent to be able to use it.
(Important note: whether something is a “polearm” or “two-handed weapon” is all about length - 42-60" for two-handers, 60-84" for polearms - rather than shape. A 72" sword is a polearm as far as the rules care.)
Other skills: Heroic skills are a classic in Dawn, and one of the main ways to up your combat potential. You can get 2 hero points for 1xp, and then add a third for another 2xp (and a fourth for 3xp). All these hero skills cost a point to use; you get your points back overnight, and there are potions to recharge them.
Weapon calls are pretty handy, especially SHATTER if you’re using a weapon between 42" and 60" (and therefore the right size to use the Shattering Blow skill).
Hero skills also allow self-healing. Second Wind gives 3 hits back as long as you still have at least 1 left, so it’s good for staying in and winning fights. Unstoppable gives 1 hit back when you’re on 0, so it’s really good for staying alive if you get dropped and left behind. I thought that meant Second Wind would be more fun for me until I started getting annoyed by my unusually high rate of character death, but that’s a bit beside the point - you can decide for yourself if you’re more interested in winning fights or surviving them.
You can also pick up a bit more of a support role - Get It Together gives an ally 3 hits back, Stay With Me gives an ally on 0 hits one back. I think Stay With Me is a lot better for the simple reason that you know when you need to use it, because your mate is lying on the floor dying. It’s a very good skill for daring rescues, which are exactly the sort of thing the Dawnish like to make their name with!
Onto stuff that isn’t fuelled by hero points!
Endurance is handy for that bit of extra fighting power; it starts looking better than the self-healing if you’re getting healed a lot. Might be worth asking your group - if they have a Physick or some healing magicians it’s really handy, especially if you can get a few more ranks from magical items.
Fortitude helps you not die - a decent way to spend a spare point.
Another way to spend a spare point, but one that requires a bit more confidence with some roleplay and is a bit less fighty: Chirurgeon. This lets you take a character from 0 hits to 1 hit with 30 seconds of Doing Medicine. It’s only 1xp and great for keeping your mates alive (more of those Daring Rescues), but it takes you out of the thick of the fighting for a chunk of time, which may not be what you’re after.
Off the top of my head, a build:
2: Shield Use or Weapon Master
1: Hero Points
2: Another Hero Point
2: Second Wind or Unstoppable
1: Fortitude or Chirurgeon
That’s just one example - another would be Weapon Master (2), 3 hero points (1+2 as above), Shatter and Endurance, making you a touch tougher and able to break an enemy’s defence quite easily.
I can help more specifically if you have any specific thoughts on what you want, especially if you know what weapons you might be using.
Thiiiiiiiis got long. I tend to get quite into it when explaining stuff - not sure if I need to apologise or not.
