Snare

This spell enables the druid to make a snare which is 90% undetectable without magical aid. 

The snare can be made from any supple vine, a thong, or a rope. When the snare spell is cast upon it, the cordlike object blends with the background of its location. One end of the snare is tied in a loop which will contract about 1 or more of the limbs of any creature stepping inside the circle (note that the head of a worm or snake could also be thus ensnared). 

If a strong and supple tree is nearby, the snare will be fastened to it, and the dweomer of the spell will cause it to bend and then straighten when the loop is triggered, thus causing 1-6 hit points of damage to the creature trapped, and lifting it off the ground by the trapped members (or strangling it if the head/neck triggered the snare). 

If no such sapling or tree is available, the cord-like object will tighten upon the members) and then enwrap the entire creature, doing no damage, but tightly binding it. 

The snare is magical, so for 1 hour it is breakable only by storm giant or greater Strength (23); each hour thereafter, the snare material loses magic so as to become 1 point more breakable per hour — 22 after 2 hours, 21 after 3, 20 after 4 — until 6 full hours have elapsed. At that time, 18 Strength will break the bonds.

After 12 hours have elapsed, the materials of the snare lose all of the magical properties, and the loop opens, freeing anything it had held. 

The druid must have a snake skin and a piece of sinew from a strong animal to weave into the cord-like object from which he or she will make the snare. Only mistletoe is otherwise needed.

The material of the noose can be cut with any magic blade, or a non-magical sharp instrument with a "to hit" bonus of +2 or better.
