• Surprise: Characters surprised by a basilisk meet its gaze.
• Petrifying touch: Anyone touched by a basilisk is turned to stone (save vs petrify).
• Petrifying gaze: Anyone meeting a basilisk’s gaze is turned to stone (save versus petrify). Unless averting eyes or using a mirror, characters in melee are affected each round.
• Averting eyes: –4 penalty to-hit; the basilisk gains a +2 bonus to attack.
• Mirrors: The reflection of a basilisk is harmless. Fighting by looking in a mirror incurs a –1 penalty to attack. If a basilisk sees its own reflection (2-in-6 chance), it must save or be petrified.
