As I add more items to my Planescape campaign that have powers based on certain planar keywords in the area, I decided it was time to expand on the idea that certain spells can temporarily apply new keywords, as well as to add a new spell to do that directly and efficiently.

The following spells (generally spells of 2nd level+ that have an area and a duration) may temporarily add a keyword to a location. This is generally within the spell’s area of effect while it is active (though for some, the spaces adjacent to the spell effect also count).

Spells do not benefit from their own added keyword (e.g., Darkness does not immediately add the Dark keyword and then also increase in potency because of that keyword).

Spells in realms that have an opposed keyword may simply disable the opposed keyword in their area, rather than adding the keyword (e.g., casting Daylight in a Dark realm). (Some countering keywords make more obvious sense than others to ensure there was a way to counter every keyword.)

Planar Haven

4th-level transmutation

Casting Time: 1 action
Range: Self (20-foot radius)
Components: S, M (an icon worth at least 100 gp crafted of materials native to a realm that has the desired keyword and designed to reflect that keyword)
Duration: Concentration, up to 8 hours

You surround yourself with a bubble of adapted reality, imposing some of the resonance of another realm upon the place you are standing. Within the area of effect, which moves with you, the selected keyword is added to those of the realm (or an opposed native keyword is suppressed within the area). If the realm has an environmental effect linked to a keyword (e.g., ongoing fire damage in a Hot realm), that effect is suppressed within the area when the keyword is countered (at the GM’s option, particularly intense or iconic effects may only be reduced). Similarly, if the realm lacks a desirable feature, adding a relevant keyword may add it to the area (e.g., Tempestuous to add breathable air to a realm that is otherwise void, or Fluid to permit liquid water to exist in a realm that otherwise makes it evaporate quickly).

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you may add an additional keyword for each additional spell level over 4th level. You require a separate icon for each keyword, and cannot “double up” to remove a keyword and then add its opposite.

This spell is available to all spellcasting classes.
