Dimensional Lock

My party is about to enter the Guiltspur Depths in part 5 of the Shattered Star AP, Into the Nightmare Rift. This entire part of the dungeon is subject to the spell Dimensional Lock:

You create a shimmering emerald barrier that completely blocks extradimensional travel. Forms of movement barred include astral projection, blink, dimension door, ethereal jaunt, etherealness, gate, maze, plane shift, shadow walk, teleport, and similar spell-like abilities. Once dimensional lock is in place, extradimensional travel into or out of the area is not possible.

A dimensional lock does not interfere with the movement of creatures already in ethereal or astral form when the spell is cast, nor does it block extradimensional perception or attack forms. Also, the spell does not prevent summoned creatures from disappearing at the end of a summoning spell.

My first question is, does this spell prevent teleport etc within the area, say from one side of a room to another, or does it only prevent it from entering and leaving the targeted area?

I would have thought the former, but am happy to be proved otherwise.

My second question is on summoned creatures. In the description above, it states that "the spell does not prevent summoned creatures from disappearing at the end of a summoning spell". Does that mean that they can't be summoned into an effected area in the first place?

Regards

Prux.


I would say that it blocks teleportation to the other side of the room.

The reason is that if you look up teleportation's general rules under the conjuration school section early in the CRB, it mentions that teleportation always briefly passes through the astral plane.

Thus, you left the area (into the astral plane) then you came back into the area, on the other side of the room. So you are blocked for leaving and entering the area.

However, if there exists some teleporting spell (not actually in the teleport subschool, but moving people around anyway) that doesn't mention going through another plane, then I would say that would not be blocked within a locked area. But I can't think of any such spell.

To answer the first question, yes, Teleport is blocked whether it is from one side of the room to the next if the whole room is Dimensional Locked and it prevents Teleport into or out of the same area.

As for the second question, you cannot summon a creature into a Dimensional Locked area but they can leave when their time is up. This is a game mechanic to avoid shenanigans with permanent or long duration Dimensional Lock or Dimensional Anchor from allowing summoned creatures to stay longer than the duration of the spell or forever. So, yes. they cannot be summoned in the first place.


The Astral Plane is used for the Teleport spell (CRB, pg 440), so no, they could not teleport (or use any similar ability) within the Dimension Locked area, as that would involve extradimensional travel.

As for Summoning, I'd say that it blocks such powers when they're cast inside it. However, if there was a Summoner character in the party, I might at least relent to the point of giving them (and only them) what's basically a Spell Resistance roll to overcome the lock each time they try to summon something, simply because they have so few other powers and, ideally, a player shouldn't be made functionally useless for an extended period of time. That's... kind of anti-fun, y'know? XD I'd probably flavor it as "mastery of Summoning" allowing them the chance to try and overcome the lock.


Oh forgot the second half of the question.

It should block summoning spells yes, unilaterally

CRB summoning spell rules:

Quote:
A summoning spell instantly brings a creature or object to a place you designate. When the spell ends or is dispelled, a summoned creature is instantly sent back to where it came from

Very clearly entering/exiting the area, which is blocked. Exiting is given an explicit exception by Dimension Lock, so that's okay, but entering isn't. So no summoning spells will bring anything in.

If it's an Summoner, they still have things useful to do even if their Summoning SLA's and spells are blocked. They can still bring their Eidolon into the area, they just can't summon it once they're inside. APG Summoners also have powerful spells at their disposal.


Depends, in part, on the exact build for the Summoner in question. XD I have a Master Summoner right now, for example, and they'd be TOTALLY useless in a Dimension Locked area. If they can be effective - "if" being the most important word here - then I probably wouldn't give them the boost. Otherwise, I would.
