Description: This spell magically holds shut a door, gate, chest, window, or shutter and locks it. You can freely pass your own arcane lock without affecting it; otherwise, a door or object secured with this spell can be opened only by breaking in or with a successful dispel magic or knock spell. If these spells are cast at a higher level than your arcane lock spell, they automatically open the lock, otherwise a spell attack against your DC is necessary to do so. Doors locked by this spell gain a +10 bonus to their break DC.
Level 0: At level 0, this spell opens and shuts doors, chests, windows, or other containers provided they weigh less than 30 lbs. At this level, doors are not held shut, nor can the spell open a door that is stuck, locked, barred, or held shut.
Leveling: At level 2, when cast with 25 gp worth of gold dust, this spell becomes permanent. Level 4: If anyone besides you opens the door by any means, including through the use of dispel magic or knock, the door explodes outward dealing 5d6 points of force damage to all within 20 feet of the door (Dex save for half).
