Just to be sure - you are overcome, you DONT pass. You pass on the next turn if you are STILL overcome, so there is one last chance for somebody to do their magic to help you.
Then you pass and NOTHING will make you unpass. Right?
Correct. Regardless of voluntary or forced passing, passing is until the end-of-the-round. Btw. before the passing (voluntary or forced), the last visible penalty of the Raider on the right is triggered... one last time.
Don't forget your uncollected defense-symbols of a passed Samurai still trigger their respective penalties, when the round is over and evaluated.
