Man, I wish I had spoiler tags on this site, or I'd have responded earlier. To get rid of the listed Flaws:
Nervous Wreck: Use 10 Vis on the unit.
Despondent: Give 10 20 stat buffs or other beneficial effects to the unit. (Doesn't count self-only buffs like the Hunter's Take Aim and the Skirmisher's Work Up, and doesn't count pure healing effects, but does count mixed healing/buff effects like the Hunter's Healing Herb and the Cleric's Inoculate.)
