This part makes no sense to me.
"In most circumstances, Wounds are a shared Consequence that players overcome as a group.A Risk with a Consequence of 10 Wounds, for example, can be overcome by any and all players.
"If the Consequence is not fully over come... all Heroes are dealth the remaining Wounds.
"A Hero who wishes to protect her friend can choose to take some or all of the Wounds that would be applied to her ally, so long as the Hero is in a position to help and spends one or more Raises.
If the wounds are a shared Consequence, why would you ever spend Raises to take another heros Wounds, rather than reduce the shared Consequence with your Raises. It seems one Raise at the shared Consequence stage reduces the whole parties potential Wounds by one, but once you get to dealing remaining Wounds as damage to individuals the same one Raise, just shifts Wounds rather than elimiates them. So your ally takes one less but you take one more.
