Savage Worlds Showdown is the skirmish rules to PEGINC's Savage Worlds RPG. They have free test drive rules for their RPG that help out a bit. You can grab 'em here:
http://www.peginc.com/Downloads/SWEX/TD06.pdf1 - Here's what the Test Drive rules say about Toughness "Toughness is equal to 2 plus half the character’s Vigor. Add the bonus granted by armor worn on the torso to this value, but remember it may not count if attacks target other parts of the body. (Half of Vigor d6 is 3 + 2 + 2 (chain armor) = Toughness of 7.)"
2 - Fear exists in the Showdown rules. It's listed as a spell on page 18 and it's game effects are on page 34. Looks like they forgot to include the point cost - it is the Alpha version of the new Showdown rules ... I'd go with 5 points - same as having the spell.
