Tie

By means of the tie spell, the caster can magically cause the object of the magic -- thread, string, cord, rope, or even cable -- to tightly knot itself to either its other end or an end of a similar object within 1 foot of it. The resulting knot is a normal one, such as a square knot, half-hitch, running bowline, or so on, whatever common knot is desired.

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.
