Ice Climbing - Good Luck and Bad Dreams

Went to climb good luck and bad dreams, but pillar cracked all the way across kicking into it. May have been solid and just needed to resettle after cold night, but opted for the mixed start. Climbed bad luck and good dreams and continued to the top. Ice was brittle. Started day at -16 and got up to -9 degrees. 0-5cm of snow on ground with hoar frost.
