Arcane Aperture

Casting Time:

Action

Range:

Touch

Components:

V, S, M (a key)

Duration:

Concentration, up to 1 hour

When you cast this spell you touch a door, marking it as your destination door. The target door must be manufactured and not a natural opening such as a cave.

For the duration of the spell you can use your action to touch a flat solid surface that is on the same plane of existence as the target door. When you do so, you create an arcane door which remains open until the spell ends. If you use this action again before the spell ends, the previous arcane door disappears.

Looking through the arcane door allows you to see through the destination door. The arcane door is large enough to allow Medium creatures to pass through unhindered, emerging instantly out of the destination door. The destination door remains unaffected, and cannot be used to travel back to the arcane door.

You can use only one Arcane Aperture spell at a time. If you cast this spell again, the effect of another Arcane Aperture spell ends.

At Higher Levels

When you cast this spell using a spell slot of 4th level or higher, the duration increases by 1 hour for each slot level above 3rd. When you cast this spell using a spell slot of 9th level, the spell does not require concentration and lasts until dispelled, or you dismiss it (no action required).
