Gate of the Faithful

3rd-level abjuration

Casting Time: 1 minute
Range: 30 feet
Components: V, S
Duration: 8 hours
Classes: cleric, paladin

You infuse a door, gate, portal, or opening such as an archway or colonnade in your stronghold with a magical field that repels creatures that do not worship your deity.

Creatures that share your patron or wear its holy symbol can move through the gate of the faithful without impediment, but other creatures attempting to enter the gate are pushed back 5 feet and stunned for 1 round (Constitution saving throw negates). Creatures failing their saves thereafter are poisoned for 1 round (Constitution saving throw negates) if they move or begin their turn within 10 feet of the gate of the faithful. Once a creature successfully saves against this spell, they can freely move through the gate.
