D&D 5E Mordenkainen's MOBILE Mansion? Opinions wanted

[AaronOfBarbaria]

A portal for an MMM spell has to be drawn on a solid surface big enough to be used as a door for the caster.

That's an interesting house-rule; certainly makes it clear where the spell can be cast... but, drawn with what? Do you still require the material components mentioned by the spell text (an ivory carving of a portal, a bit of marble, and a tiny silver spoon) in addition to the drawing materials?

A portal for an MMM spell has to be drawn on a solid surface big enough to be used as a door for the caster. It is always fixed and immobile relative to the frame and surface it is painted on...

Demiplane specifies that, this edition of MMM doesn't, but it would certainly fix the OPs problem.

Rubble rost raggy!

I think we need a new spell: Mord's Mobile Home. But you can only summon it while in Mord's Trailer Park.

If you upcast it at a higher level you can get Mord's Double Wide.

Just as a note, Leomund's Tiny Hut specifies an IMMOBILE dome in the spell description, while neither Mordenkainen's Private Sanctum and Magnificent Mansion make any mention of being immobile.

Which still brings up the question "immobile in comparison to what?".

That's in Mobile, AL, right?

Maybe not physically drawn per se, but the portal has to have a clear set of dimensions on a solid surface, even if it is a shadow or the border formed by the seams of mortar in a brick wall, or the lines formed by cracks in plaster. There has to be some kind of visual delineation for the caster to focus on. You could not make a portal on the surface of a pool of water. It has to be an object you could in which you could install a door. But if you wanted to have a clever way to conceal a door, you could put it in a stone circle where a panel of light hits a specific spot once a year. The caster would have to be there that day to enchant the pattern of light hitting the monolith so it becomes a physical door. Anyone looking for the door would have to know when to look for it...

^^^Yeah, what she said.

Could you inscribe a permanent teleportation circle on the top of an enclosed wagon? That seems a little more abusive, kind of defeating the point of teleportation circle.

For Mordenkainen's magnificent mansion, I'd rule that any place big enough to support a physical door to a physical room qualifies. So, a rowboat -- no. Ship -- yes. Wagon -- maybe, if it was an enclosed wagon and the door was on the back; that seems like it could hold a door and a room. But like a dinky little wagon full of watermelons -- no, it would tip over from the weight.
