Untie

When the untie spell is cast, the caster selects an object-thread, string, cord, or so on -- that is knotted or tied. The spell removes the knot or tying. This spell cannot remove both a knot and a normal tying (normal knot or one caused by a tie spell), but it causes the former to disappear, so that only a normal tying remains. This spell has no effect on magical objects.

Note: This spell originally appeared in this form in Unearthed Arcana for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
