The subject can climb and travel on vertical surfaces or even traverse ceilings as well as a spider does. The affected creature must have its hands free to climb in this manner. The subject gains a climb speed of 15 feet and a +6 bonus on Climb skill checks (+10 on Climb checks to traverse a vertical or horizontal surface, even upside down). A spider climbing creature retains its Dexterity bonus to Armor Class (if any) while climbing, and opponents get no special bonus to their attacks against it. It cannot, however, use the run action while climbing.
Per AD&D: During the course of the spell the recipient cannot handle objects which weigh less than 50gp, for such objects will stick to the creature’s hands/feet, so a magic user will find it virtually impossible to cast spells if under a spider climb dwoemer.
