These will appear to be a set of magic leather boots which form-fit to any wearer. During testing, they will allow the character to climb walls and ceilings like a spider, moving along vertical and horizontal surfaces at up to 1/2 normal speed. When first used when really needed, however, the boots cast a Paralysis spell on the user (no Save), and stick them to the floor or ground as if glued there. The effect lasts 1d10 rounds.
Any attempt to climb walls while wearing them after this, either from using the magic of the boots, or through any other means, will result in Paralysis again. The boots can only be removed at this point through a successful Remove Curse spell.
