Vault Seal

You inscribe an arcane sigil on a door, gateway, or vault entrance, sealing it with a potent magical barrier.

The sealed entry cannot be opened by mundane means.

• Teleportation and Divination spells targeting within the sealed area fail unless the caster succeeds on a DC 18 spellcasting ability check.
• Dispel magic can end the effect provided the caster makes a successful DC 18 Arcana check to Unweave the spells magics. On A Failed Dispel Magic check the caster takes 4d6 psychic damage.
  
  *Additionally any attempt to disrupt or dispel this "Vault Seal" are immediately known to the spells caster.

This spell affects objects, Areas and structures only, never creatures. (Dm discresion what is an appropriate target for the spell)
