Passwall

A passwall enables the spell caster to open a passage through wooden, plaster, or stone walls; thus he or she and any associates can simply walk through. 

The spell causes a 5-ft wide by 8-ft high by 10-ft deep opening. Note several of these spells will form a continuing passage so that very thick walls can be pierced. 

The material component of this spell is a pinch of sesame seeds.
