Hold Portal (1st level mage)

Casting Time: 1 action
Duration: 1 min./lv.
Range: 100 ft + 10'/lv.

This spell magically holds shut a door, gate, window, or shutter of wood, metal, or stone. The magic affects the portal just as if it were securely closed and normally locked. A knock spell or a successful dispel magic spell can negate a hold portal spell. Add 5 to the normal DC for forcing open a portal affected by this spell.
