Critical Success The creature is unaffected.
Success The creature takes (3d10+5) cold damage.

Critical Failure
Disable DC 53 arcana (legendary) to draw a fiery counteracting glyph over each snowflake, or Dispel Magic (9th rank, counteract DC 48)
Miniature snowflake-shaped glyphs on the ground cause a layer of ice to ripple over the floor of the room and sound a silent alarm.
