My character, Lyra, is more or less a support character, or at least I've given her abilities that let her function in that role. All of her first level spells can be used to help other people in the party, especially Mage Armor and Cure Light Wounds. She can also use Heavenly Fire five times a day, which gives her a 30ft radius 1d4 healing ability, but only for good characters, which at least seems to be most of us? (It also does 1d4 damage against evil creatures, which is a neat bonus.) She's also got Bit of Luck, she can use once per day to let someone roll a d20 twice and take the higher result, and Karmic Blessing, which lets her temporarily turn someone's skill into a class skill.
As for actual combat abilities, she's mostly just got her crossbow, which at least lets her keep some distance between herself and enemies. Unerring Weapon will help with that, though, since the crossbow has a greater critical threat chance (19-20 instead of just 20) and that spell makes it easier to confirm a critical hit.
And since we're going to be traveling a lot, I gave her the trait Starchild, which basically makes her a living compass, and gives me a +4 bonus on rolls to avoid becoming lost.
Her stats are mostly pretty good, but she's pretty frail in terms of strength and constitution (and only has 5 health, and can't use physical armor) so she'll need to avoid getting hit too much.
