Domain of Sanctification

This spell is performed as a Holy/Druidic Ritual. You inscribe a large glyph covering an area 10 ft in diameter on an object or surface. After casting, the glyph will remain in effect indefinitely unless:

• Magically dispelled
• Access to the deity/natural essence^ in the area is cut off
• The surface or object is moved more than 10 feet from where you cast this spell
• The glyph is destroyed

If any of these occur the domain and its effects will fade over 2 days. 

The ritual must be performed in an area with access to the casters deity/natural essence^. (At the DM's discretion) For example this spell cannot be performed in areas under the domain of other deities for clerics or separate from the natural essence of a druids chosen circle. The sanctification domain is overlayed over any existing domains/area effects and does not dispel them. But once in place, a sanctified domain will prevent new domains/area effects antithetical (up to DM interpretation) to the casters deity/natural essence^ being created within. Repeat castings allow for additional creatures to be added to the effect.

The glyph is easy to find but hard to decipher and requires a successful Intelligence (Cleric: Religion, Druid: Nature) check against your spell save DC to identify.

This glyph is powered by the energies of a cleric's deity or a local source of a druids 'natural essence'^.  The surrounding area within a 200 ft diameter sphere is sanctified as holy land under the domain of the casters deity/natural essence^. This sanctification prevents any other caster with a different deity/natural essence from casting Domain of Sanctification while within range. Any Cleric/Druid of the same deity/natural essence^ is empowered while within the sanctified domain and gains Advantage when casting non-attack spells within it. Any Cleric/Druid of a different deity/natural essence^ is suppressed while within this foreign domain and suffer Disadvantage when casting non-attack spells within it.

Choose one or more of the following types of creatures: celestials, elementals, fey, fiends, or undead.

• The creature can’t willingly enter the sphere by nonmagical means. If the creature tries to use teleportation, interplanar travel, or is compelled magically to do so, it must first succeed on a Charisma saving throw.
• Targets within the sphere can’t be charmed, frightened, or possessed by the creature.
• The creature has disadvantage on attack rolls against targets within a 10 ft cylinder around the glyph itself.

This spell is intended to interact independently for Clerics and Druids, being different forms of magic. So, Cleric domains affect other Clerics and cleric deities only; and Druid domains only affect other druids and their natural essences*. It has been written to try and accommodate both flavours with the same core mechanics.

^ The 'natural essence' for a druid can be interpreted as needed, as a starting point should be the essence of the chosen land type (Circle of the Land), or essence of the moon (Circle of the Moon). 'Access' to these natural essences requires the immediate surroundings of the caster have a significant presence of that essence: land types should be present when casting (Eg. in a forest/glade), elemental/ethereal essence types should be directly exposed to it (Eg. bald hill exposed to the moon).
