Questions about ring gates


Rules Questions


Ring gates seem like a really fun, but confusing item. Reading through the description I was left with several questions that I can't find an answer too. Any help is appreciated.

1. Can you see through a ring gate? If so is it one way or bidirectional? I assume yes because you can cast spells through it.

2. Speaking of spells. Do you calculate LoE and LoS using the gate or does the exit gate need to be in range of the spell from you? If I have an unseen servant carry the ring is its effective range now 100 miles?

3. What about area spells and emanations? If I cast lightning bolt can it pass through the ring?

4. Pressure differences. Would a ring gate at the bottom of a lake shoot out water? Would the solid stream be a continuous item or would it clip at 100 lbs?

5. What happens when something goes in the exit side? Does it pass through harmlessly? What about if someone sticks their arm in the exit side and leaves it there? How would that affect normal use?

I am sure I will think of more. But if anyone knows about the above it is appreciated.


Ring Gates:
-----------------------------------------------------
These always come in pairs—two iron rings, each about 18 inches in diameter. The rings must be on the same plane of existence and within 100 miles of each other to function. Whatever is put through one ring comes out the other, and up to 100 pounds of material can be transferred each day. (Objects only partially pushed through and then retracted do not count.) This useful device allows for instantaneous transport of items or messages, or even attacks. A character can reach through to grab things near the other ring, or even stab a weapon through if so desired. Alternatively, a character could stick his head through to look around. A spellcaster could even cast a spell through a ring gate. A Small character can make a DC 13 Escape Artist check to slip through. Creatures of Tiny, Diminutive, or Fine size can pass through easily. Each ring has an “entry side” and an “exit side,” both marked with appropriate symbols.
-----------------------------------------------------

There's arguments for some of these, so I'll just lay out some thoughts.

1. Can you see through a ring gate? If so is it one way or bidirectional?

Could be either way. Despite saying you can cast spells through it, or attack through it, that doesn't mean you can see. You could cast a touch spell and reach through, or you could stick a hand in and fire a lightning bolt (possibly even cast the lightning bolt through it, but that's a different question).

Quote:
... a character could stick his head through to look around.

You wouldn't need to stick your head through to look around if you could see through it. Although, it could be read as letting you stick your head in and look around the ring gate to see a different angle that isn't in the field of view, it's possible that this is meant to mean you can't see through it and need to risk putting your head through.

Quote:
2. Speaking of spells. Do you calculate LoE and LoS using the gate or does the exit gate need to be in range of the spell from you?

If you allow spells to be cast through the gate, ie. if you cast a lightning bolt (120 foot line) from 20 feet away that passes through it, (rather than stick your hand through and cast it), then it would still travel 100 more feet, even though the actual distance it would be away from you would be more than the 120 foot range allowed by the spell normally.

Quote:
3. What about area spells and emanations? If I cast lightning bolt can it pass through the ring?

If you allow spells to travel through the gates, then emanations should as well. I personally don't like the possible ramifications, but that's more personal than rules objective.

Quote:
4. Pressure differences. Would a ring gate at the bottom of a lake shoot out water?

I wouldn't think so. Almost all the text talks about objects being 'put through', 'placed', 'pushed', or 'cast' through the rings. I don't think it implies incidental atmosphere or environment.

Problems:
--------------------------------------------------
If that were so, your GM would have to calculate the weight of air (about 0.08 lbs per cubic foot). That means about 1,250 cubic feet of air could pass through a ring gate before they shut down. Then they'd have to figure out how much cubic feet of air would naturally drift, flow, or get blown through an 18 inch ring each round. Even if you assumed only 1 cubic foot of air transferred through a ring each round, that means you'd have 625 rounds (because there's two rings, so air would be moving through each one and coming out the exit side of the other, and the transferred weight is total between the gates). At 10 round per minute, that means each gate would only stay open a maximum of 63.5 minutes (about 1 hr), assuming nothing else went into each ring.
Then, if someone did want to pass something through, say 45 minutes in, the GM would have to calculate the current transferred weight to make sure the new items weren't too much. That all seems a bit far-fetched and problematic.
-------------------------------------------------------

Probably best to just restrict it to things that are purposefully placed or put into the ring gates.

5. What happens when something goes in the exit side? Does it pass through harmlessly? What about if someone sticks their arm in the exit side and leaves it there?

I certainly don't think it would be harmful. If it severed limbs or caused an explosion, I think that would be mentioned.

Most likely, it works just like sticking your hand through a normal ring. It would just pass through (and pulling your arm back through would be fine). If you somehow had an 18 inch across arm (or close to it), then it would plug up and prevent anyone from putting anything into the entry side while your arm was there, requiring them to either push it back through or sever your arm.
Otherwise, you could just make it impassible while the gates are open, that would be easiest, but might lead to some players trying to use it as a shield or other form of defense to deflect bullets or spells or something.


Thanks for taking the time to respond. A lot of what you said aligns with my initial impressions.

1. Spells require you to see your target so yes, you can see though them, I would assume both ways

2. I agree with Pizza Lord on this one.
3. Again, I agree with Pizza Lord.
4. yes, gates work both ways, pressure is the same as pushing something through, but remember only 100 pounds per day. So only about 12 gallons of water from the bottom of the ocean.
5. Something must happen when you enter the exit side. otherwise you couldn't retract your arm once you reach through. I view it as each one has a side A and a side B, what goes in side A on one comes out on side B on the other and vice versa.


Ring Gates $40000. Different than in 3.5(were smaller, long distance) and now not very useful for the price.

See that would make sense. But the way the item is written is that there is an exit and an entrance on each ring. So if you go into one ring's exit how does that affect someone using the entrance that goes out through that exit?

If it were A to A and B to B for each ring it would make a ton more sense.


Gate which is the spell in the item's requirements.

Permanency is the other spell but gate is not in the RAW list. Teleportation Circle is on the list at $22500. So for double the price you can transport a significant amount (med creature with gear per round) to and fro.

chalk it up to a poorly written item. All I know is that since it specifically mentions putting your head in, you have to be able to retract it. that means that if you put things into the "Exit" on one, they come out the "enter" on the other.

So I don't care how you label them, the gates are 2 way, in and out, one side of gate A is linked to a side of Gate B, and most likely the other side of Gate A is linked to the other side of Gate B. the only other reasonable conclusion is that the gates only have a single functioning side and things can go in and out freely between the two.


it is probably enlightening to read the item AND the spell used to create it. See my above two posts. *-<8^)

I saw it more as going through a push door with no handle on the other side. You can open the door, poke your head out, pull it back with no issue. But if you put something through or walk out the door and the door closes you can't come back in that door and need to go in the entrance on the other side.

I will definitely agree on it being poorly worded. Thanks for the feedback!


To try and answer question 4, I direct you to Pathfinder Campaign Setting: Dragons Unleashed page number 7,

"One ring gate; when activated, it gushes salt water at an
incredible rate and pressure, as if the other ring were
deep in a vast ocean (worth 20,000 gp)."

I hope that helps.

My responses for what they're worth.

1. Can you see through a ring gate? If so is it one way or bidirectional? I assume yes because you can cast spells through it.

GM call but I'd say yes. I don't recall seeing a "default" portal description anywhere but most descriptions I've seen have you viewing an "otherwordly" environment on the other side however there are some you can't see through.

2. Speaking of spells. Do you calculate LoE and LoS using the gate or does the exit gate need to be in range of the spell from you? If I have an unseen servant carry the ring is its effective range now 100 miles?

Use yourself as the origin point as usual but calculate distance through the gate not around it. It is essentially a shortcut though abuse of this may have a GM introduce their own rules. Generally speaking however that is . . .

You|Otherside

Not

You . . . . . . . . . . . . . . . . . . . . . . . Otherside

The gate negates the distance between otherwise spells would fizzle and stop as soon as they hit it because of the distance. As long as your spell is cast THROUGH the gate not around it though you can do that too.

3. What about area spells and emanations? If I cast lightning bolt can it pass through the ring?

As above yes. I don't recall any portal rules but the whole point of these items is to negate that inbetween distance or you couldn't reach an arm through either.

4. Pressure differences. Would a ring gate at the bottom of a lake shoot out water? Would the solid stream be a continuous item or would it clip at 100 lbs?

Yes it would go through as the pressure difference is "pushing" objects through the gate. Note the 100lbs limit is per day and doesn't apply to objects partially through then pulled back. So you would have 100 lbs of water (or other) gush out each day then cut off as the portal becomes unuseable when you hit that limit.

5. What happens when something goes in the exit side? Does it pass through harmlessly? What about if someone sticks their arm in the exit side and leaves it there? How would that affect normal use?

This is sort of difficult to describe, easier to draw it works like this.

-> Entry ring oneExit ring two ->
-> Exit ring one ->

This image is what you'd see (smaller ring) if you look through the Portal entry. Around you and around the ring is a forest through it is a mountain range. I'll use this one to show how it'd look as someone comes thorugh from the exit side. of the second ring. There's a ring (or in this case square) in the air, a field in and around it and this strange free person just appearing there out of thin air.

Now if you walk around the ring and look through the exit side of the first ring you will see the forest., stick an arm through it and someone on the entry side will see your arm sticking out of their mountain range view but they'll also see you standing behind the ring assuming your tall enough to look over the top and from your perspective you've stuck your arm through a ring . big whoop. You can stick your arm through harmlessly and leave it there it'll only cause an issue in the person using the ring has to squeeze past it. From the entry side there's an arm in front of them they need to pass to get to the portal and from ring 2 side there's your bisected arm in their exit way.

I wouldnt recommend it though as if they decide to push your arm from that sliced off but not bleeding stump they're looking at rather than the side their hand will wind up inside your arm and the GM will need to work out what happens then.

Edit
Swapped Dr Strange book stealing for a better image showing the view from the exit side. In fact here's another one.

Not entirely happy with either image for the exit side but they give the idea. Looking through the ring you see what's there where you are, someone coming out of it is basically sliced off where they pass through the portal and you can't see it. Stick something through from the exit side and your looking at your arm through a ring and from the entry side you see another land but still your just sticking an arm through from your perspective.

Things to remember:

In real life:
A cubic foot of water weighs approximately 62 lbs.
A cubic foot of water will have approximately 7.5 fluid gallons (US).
A gallon of water (US) weighs approximately 8.3 lbs.

In Pathfinder (as per create water):
A cubic cubic foot of water weighs 60 lbs.
A cubic foot will have approximately 8 gallons.
A gallon of water weighs 8 lbs.

So we'll go with the Pathfinder stuff.
A ring gate is 18 inches in diameter (1.5 feet across).
Can't really tell how much water comes through per round (that depends all on pressure). But we can safely assume it will be at least 12 to 18 inches; so a 1 to 1.5 cubic feet of water.

That means, if we assume that an equal cubic amount of water is pressed, pushed, or pumped through the gate, you're looking at approximately 60 pounds (1 cubic foot) to 90 pounds (1.5 cubic feet) of water coming through per round.

You'll end up with about 12 gallons of water coming out. The force or pressure will vary, but it probably won't be much unless the ring gate is at a depth with incredible pressure (assuming a normal sea-level pressure on the other side).

12 gallons is how much a create water spell from a 6th level caster makes, or a 1st-level one casting it 6 times in a row (it's a cantrip, so free).

The ring gates aren't staying open very long. About 2 rounds and then they're done for the day.
