D&D General Keys for Planar Portals

[JediSoth]

Planescape used a variety of different things to active portals in Sigil (and elsewhere in the planes) ranging from the mundane (a rusted key) to the metaphorical (the bottled sigh of a forgotten hero).

What are some other good planar portal keys?

(IIRC, there isn't an official list; it was pretty much GMs discretion)

1. The final acorn from a dead oak
2. A leaf from Yggdrassil
3. A cobblestone from an endless street

4. A discarded bit of smelly Vogon underwear.
5. A source of Brownian motion.
6. Salted nuts that have, themselves, traveled across planes.

7. A teardrop from a drowned efreeti noble
8. A three-sided square
9. A horseshoe from a nightmare

 

[Malmuria]

10. A stolen tiefling baby
11. An ample amount of garbage
12. The feeling of lassitude

For more metaphorical planar actuators, I suggest watching Everything, Everywhere, All At Once. They get pretty wild.

13. A love-letter that reached the wrong recipient.
14. A recited nursery rhyme that terrified you as a child.
15. A freezing breeze on a midsummer day.
