And finally here is character #3.
Marta is a Human Sanctified Slayer-Ravener Hunter Inquisitor connected to the Pharasman cathedral in Lepidstadt. Ravener Hunter gives her 2 revelations from an Oracle mystery. She's taking Battle and grabbing Skill at Arms for her first one to get proficiency in martial weapons and heavy armor. She'll be using a greatsword, and possibly a reach weapon depending on party specifics. She'll switch to plate armor as soon as she can afford it. At 8th level she can take Weapon Mastery to get both Weapon Focus and Greater Weapon Focus if her attacks's accuracy is lagging. If not, she can take War Sight to roll initiative twice. She will also have Studied Target to keep her accuracy up. The idea is to use flat bonuses as much as possible to limit the amount of spells needed for self-buffing so she help out with healing some. If I keep combat feats simple, which is possible with a strength build, I might be able to work in the 2 feats needed for good mundane healing as an alternative to more magic coming from someone.
Between heavy armor, Toughness & Power Attack, and strength over wisdom stats, she should be sturdy enough to be on the front line as a matter of course. Oh, and Marta will have sneak attack dice for those times when it's possible to pull it off.
