BBEG has cast Forbiddance on his lair to prevent players teleporting in or out, but the BBEG needs an escape hatch.
The spell says "prevents creatures from accessing the area by way of the Astral Plane, Ethereal Plane, Feywild, Shadowfell, or the plane shift spell." but that doesn't seem to mean that you can't exit it that way?
Can you use etherealness to exit an area of Forbiddance?
It is up to the DM to interpret this, but I have the feeling that the spell is worded specifically to prevent teleportation into the area only, not out the area.
I believe the wording of Forbiddance is pretty clear.
"For the duration, creatures can't teleport into the area or use portals, such as those created by the gate spell, to enter the area." and "...prevents creatures from accessing the area by way of..."
Nothing in its wording mentions preventing teleportation out, or using portals to leave, or use planar spells to leave.
Spells like Dimensional Anchor or Dimension Lock haven't made it to 5th edition yet, I believe. Possibly by design choice.
If you cast forbiddance every day for 30 days in the same location, the spell lasts until it is dispelled, and the material components are consumed on the last casting.
How does that last part work? I mean, I get it, it means that the spell only requires a single use of the material components, but... just... how??? How does the spell know you're going to cast it it multiple times in the exact same place? And even then, what happens on day 1-29? Will it not function then? But what if I cast it once, with the intent of only having it last that one day, then the next morning I think "whelp, I like it here, I'm going to cast it again"?

The castings of Forbiddance from day 1 to 29 do not consume the material component when the effect of the spell becomes permanent (until dispelled), then the material is consumed.
Like Filcat said. Spells with Material components do not consume those components unless they explicitly say so. Forbiddance's normal casting does not, so you can cast it as many time as you want with only one ruby and relevant paraphernalia, unless you cast it once per day for 30 days at the same area; when you do the 30th time, and the spell becomes semi-permanent, your ruby etc. are gone.

Ah, yeah I missed the part that the material component is normally not consumed :) Thanks!
