Bumping this to ask a question about how this ruling is treated now. I looked at the online REG and found this:
Set-aside enhancements
A set-aside enhancement has the phrase “set a (type of character) aside” in its special ability. A set-aside enhancement can be played on a character of matching brigade in your territory during your Preparation Phase or Discard Phase. Its special ability activates even though it is played outside of battle. You may also play them in battle according to the rules of initiative. You can direct the effect of the set-aside card to any character you own and currently control. You may set aside a character with multiple set-aside cards if they are played at the same time.
Is this an error, or are we currently allowed to play multiple set-asides at the same time and target the same character with them?
Also, if I put a Hero in Kerith Ravine, can I play as many set asides as I want on him during the same turn?
