Maybe already discussed about Jack, but.. with new rules, Bandage basic action got off then Fixable no make sense. Maybe to "fix" it:
"when successfully uses the Bandage basic action" ---> "when one or more wound tokens are removed by any source" (heal type support actions, heart results from successfully attack rolls, potions...)
"remove two wound tokens instead of one" ---> "remove one extra wound token"
Perhaps he going to be overpowered because of his Bumper Crop, healing himself 3 wounds while heals nearby heroes 2 wounds.
