Stargate (3.5e Equipment)
From D&D Wiki
Stargate A recent creation by the Foundryhouse of the small city of Morely the Stargate is an new method of transporting people from one place to another. These are becoming quite popular as people save up and afford their own, so that their town feels like it is next to a city.
The Gate itself is just a magical ring with 9 lights around the edge, when powered it creates a tunnel to another gate that allows for relatively safe passage to another gate(It must link to another Gate).
However the gate must be powered to be used, it takes 9 lvls of spells(Or limited use magical abilities or items) to power the gate.
15000GP (to craft need Craft Wonderous Item, Craft Staff, and the spell Gate as well as having apprenticed with a Master Gatebuilder.(Craft Cost=1200XP and 7500 GP))
|Highest lvl spell||1st||2nd||3rd||4th||5th||6th||7th||8th||9th|
|Time open||1 Min||5 Min||10 Min||30 Min||1 hour||3 hours||6 hours||12 hours||24 hours|
Depending on the highest lvl of spell spent the gate opens for a longer amount of time (though the gate that open it can close it at will) but for every increment that the gate is open the chance increases that something bad will happen.
To look at the chart above... Time open= How long the gate will be open before it collapses of it's own accord
Mishap= The increasing chance that something bad will happen
End chance= The mishap chance just before the gate closes of it's own accord
WCS= The worst case scenario at this power lvl, assuming all goes wrong.
The longer the gate is open the more likely and the worse the event is that could happen, for every group of objects that moves through the gate roll for the current mishap chance, if there is a mishap then assume that it is the 1st one in the WCS row, if the power is higher though roll a 50% chance that the mishap gets worst, then again and again, until it either doesn't get worse, or you are at the same spell lvl.
Example- Tim the Telemage is using a Stargate, he is sending a few supply wagons through, so her uses a 7th lvl spell to power the gate, this gives him a good 6 hours to get them through. 4 hours pass as he sends one after another through until he decides to go through himself. 4hours at 6%/hour is 24% mishap chance. So as he steps through he rolls it, and gets an 18, so a mishap happens.
Starting out at 100 miles off target Tim rolls another 50% and gets 25, this turns it to 1000miles... but he rolls again and he gets 35, so it changes to random plane. He shudders and rolls again, getting 26, so instead it aims to deep underground, another roll of 49 says that he is going to space, and that 10 says Amnesia with a will save... he's sweating as he rolls the next one but a 55 saves the day.
He rolls his 7th lvl save for that lvl, and manages to pass it, so no amnesia for him today, but the DM now gets to pick anywhere to put the erstwhile mage, it seems that he isn't getting to the other Stargate any time soon.
