Coin Thunderspear:
Craft and profession are always class skills, for everyone.
This gm has decreed that you need 8 hours "sleep" for recovering magic regardless of options that would normally reduce that, such as elves or rings of sustenance, so keep that in mind.
That said, pick something evocative of your character, something through which you can show who your character really is.
Anyone that needs to recover spells, yes you need 8 hours and not doing strenous activities. Elves still need 8 hours but only sleep 4 of them. Rings of sustenence doesn't effect it-it just makes it so you don't need food or water and only need 2 hours of sleep but the rest of the time if recovering spells you still need to rest and do non-strenous things like talking, relaxing, doing odds and ends, ect. It was a big debate about it but it just states you need less sleep, that's it. Its pretty good if your the scout of the group and need less time to sleep and as long as your not doing anything that provides strain its not bad a all. Warforged don't sleep which is good.
Could be a fisherman, painter, scuplting....
I thought you were going to do the craft (Weaponsmith) or Blacksmith and profession (Weaponsmoth) or blacksmith? You can take another craft skill but that does require ranks. Ballest who was here took up carpentry. Coin's a trapmaker and woodworker. Cumandria is a cook. Faolan is a stablehand. Zhera is a jeweler. And Fenris was a hunter/trapmaker.
