Flavor

A door, gate, or shutter is held fast by unseen force, resisting all but the strongest shove.

Mechanics

Magically holds shut one portal (door, gate, window, shutter) of up to 20 sq. ft./ within 20 yds./level for 1 /level. A creature can force it with a successful or a knock spell; a wizard of higher level than the caster can open it at will, and dispel magic ends it. No (verbal only).
