Rope trick

When the rope trick spell is cast upon a piece of rope from 5 to 30 feet long, one end of the rope rises into the air until the whole rope hangs perpendicular, as if affixed at the upper end. The upper end is, in fact, fastened to an extradimensional space. The spellcaster and up to seven others can climb up the rope and disappear into this place of safety where no creature can find them. The rope can be taken into the extradimensional space if fewer than eight persons have climbed it; otherwise, it simply stays hanging in the air.

Spells cannot be cast across the interdimensional interface, nor can area effects cross it. Those in the extradimensional space can see out of it as if there were a 3-foot × 5-foot window centered on the rope. Creatures in the extradimensional space will not run out of air while the spell lasts. The persons in the extradimensional space must climb down prior to the end of the spell, or they are dropped from the height at which they entered the extradimensional space. The rope can be climbed by only one person at a time.

Note: This version of rope trick originally appeared in the 2nd Edition Player's Handbook for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
