Corruption. The next character wounded by the attack (on whom a corruption card has not already been played this turn) receives 2 corruption points (place this card with the character).
Discard Icy Touch if it is not played with a character. During the organization phase, a character with this card may tap and attempt to remove it. Make a roll (or draw a #): if this result is greater than 6, discard this card.

discarded without effect.

First problem.
One of effects of Icy Touch is increasing a prowess of attack? Should it happen only once, even if multiple Icy Touch are in play?

Second problem.
Icy Touch is not played on character. It may be placed on character, if conditions are met.
So "(on whom a corruption card has not already been played this turn)" should not prevent next copy of Icy Touch from being placed on character, and should not prevent from playing another corruption card on this character in the same turn.
