The caster of this spell creates a solid bridge of crystal that spans over any one gap. The bridge is always 5 feet wide and can span a gap of up to 10 feet per caster level. The bridge must connect to two solid surfaces or the spell fails. The bridge itself can hold up to 2,000 pounds plus 100 pounds per caster level. The color and appearance of the bridge is determined by the caster when the spell is cast.
