Question that came up in a recent game: can Three Bells trigger even if one or more players do not have any characters?
The card text, for reference: "Pay 1 and exhaust The Three Bells to have each player choose and sacrifice a character."
My read is no, but I can see it either way. According the FAQ 1.5, "A player cannot trigger a card effect that requires him to choose a character, support card, or story card if there is no card of that type that he is able to choose." However . . . that may mean only that the triggering player must be able to choose a character; that is, a player may be able to trigger it if he has a character but his opponent does not (although it would be a rare case where that would be beneficial).
Next question: can Ipiutak fire off Three Bells?
My read is no, but again, I think it's close. Ipiutak reads "after a character you control was chosen as the only target of a triggered effect . . . " As far as I can tell, Three Bells will have two targets chosen (by two players). An alternate reading, however, would see Three Bells as triggering two effects, each of which has one character as the only target, which would allow Ipiutak to respond.
Finally, not a Three Bells question, but related: can Ipiutak fire off Temple of R'lyeh?
My read again is no, but again, I think it's vague. Temple clearly chooses the opponent as the target, with the opponent then sacrificing a character. There's only one character that is ultimately impacted, but I think technically it's not a target, as "choose" is not used in conjunction with it - unless it's implied?
