Hold Portal

(Spell, Abjuration)
Cast ◆◆ Verbal, Somatic, Focus
Range 30 feet; Target one portal
Duration sustained, up to 10 minutes

You magically seal shut a door, gate, window, or shutter. The portal must be closed for this spell to work. As long as the portal is not lodged open and could normally be closed with a single action, you may magically swing closed the portal as part of this spell.

While sealed, the door acts just as if it were securely closed and barred. A knock spell or a successful dispel magic can negate this spell. Destroying or forcing open the portal ends the spell. Add 5 to the normal DC for forcing open the portal.
