i'm sure this has been asked before but, for the part that states "If opportunist tokens are removed when another character makes an attack, deal the character 1 unavoidable damage after the action resolves."
who takes the damage, the character assigned this feat or the "another character" using this option...oh yea and can a figure with indomitable benefit from the willpower prerequisite?

Prerequisites: Charge or Running Shot or Willpower; point value of 50 points or more.

Choose a character.

If the character has zero action tokens at the end of your turn (before tokens are removed from characters), put an opportunist token on this card if there are four or fewer opportunist tokens on this card.

When the character or an adjacent character makes an attack, after making the roll you can remove any number of opportunist tokens from this card and modify the result of the attack roll by +1 for each token removed. If opportunist tokens are removed when another character makes an attack, deal the character 1 unavoidable damage after the action resolves.
