This is the third of the astral combat spells. Tied to the realm of water, it draws its powers from your affinity to this realm to fire a multitude of icy darts at your opponents. The chill that this causes can affect the throats of your opponents silencing some them for a short while. When they are silenced they cannot cast spells or do anything involving speech. In casting blackice you have to give up a small portion of health as well as magic to cast the spell. You may specify the target type, but if you specify player or all you do not include yourself.
