Darkest Depths

This spell opens up a yawning pit into the icy depths of the sea, sucking the target down into it. Every half-hour, an attempt is made to escape, and someone who can move freely underwater (such as via the waveborne skill or the Sunset sigil) may escape by simply swimming upwards. The pressure of the water ensures that anyone who cannot breathe underwater is unable to do much but struggle. It is entirely possible to drown in this place.
