Query, I'm looking for examples from other GMs for some of the weirdest, greatest or most powerful artifacts (be they chaos, xenos or unknown origin) as ideas for a plot I'm working on. They don't have to be weapons or armour no they can be anything. I'm just wondering what custom items some of you have come up with or experienced. The more the better, as I need a few ideas to give myself a selection when the relevant time comes.
Some I already have come up with or brainstormed with others for example (feedback welcome):
The Tome of Dimannius - A deep blue bound grimoire, this item when opened appears to contain almost infinite knowledge. It is said that its discoverer Adept Dimmanius, spent many years reading through it. Each time it was opened, pages would change and new information would be available to quench the thirst of the eternal scholar. Anything from arcane secrets and lore through to basic manuals and childrens stories, the information would be endless. Over time though such knowledge would come at a terrible price and Dimmanius eventually became obsessed with the book, first becoming reclusive before even going so far as to forgo sleep or even sustenance, not willing to part with his tome. Before his death, observers noted that for the final few months of his life it appeared the adept had even lost all sight or the capacity of speech, so focused on his reading that nothing else mattered.
Effect: Spending an hour reading through the book grants +30 to any single lore test however the reader must make a Willpower test with a -10 penalty for each time with the first test starting at +30. Should they fail this test they compulsively spend another hour reading another section and must retest.
Explanation: Basically it's that whole "know lots but it'll come back to slowly bite you". Get them obsessed with reading to the point they become frail and distracted with life in favour of reading.
Deathless Armour - Appearing as black shadowy armour, this suit of finely crafted metallic armour seems to bind effortlessly onto the body of its wearer, moulding itself as it is placed. It is said that the wearer of such armour is able to endure any assault, stand immune to any blow and laugh in the face of their adversaries. They become so sure of their immunity that over time it becomes almost impossible to remove...or is that the armour not wanting to be removed?
Effect: The deathless armour acts as unique armour which can never be penetrated, it always fits the wearer perfectly no matter how large or small they are and has no weight. Should the wearer be struck on any body part which has a piece of the armour equipped, they ignore the attack completely. Additionally once all parts are in place the suit counts as fully environmentally sealed, allowing the wearer to survive any hostile environment for an indefinite length of time even the heart of a volcano or the chill of space. The problem is though, once added it can never be removed without removal of the limb. Additionally it is not power armour and does not contain any of the nutrient capabilities or recycling capacity.
Explanation: Immunity from everything, it's like King Midas. The problem is though that you cant take off what you add. No more will you feel the wind on ones skin, if the helmet goes on then forget eating. Nice little double edged sword. Cant die from wounds but you can die from lack of nutrition or other issues...
Warp Walker Gauntlet - Dark Mechanicus experts fashioned this device using a powerful warp manipulator and a small fragment of technology fashioned from a Necron Deathmark. Observing the deathmark's ability to permanently locate and find any target wherever it may hide in warp or real space, they managed to find a way to utilise this basic tracking component into a small detachable item the size of a coin. Once planted and active, the beacon transmits a unique signal upon which the gauntlet is able to locate and instantaneously transport the wearer from their source to the locator and back again. It may also be able to recall the locator. However caution is advised as the unknown nature of Xenos technology means its reliability is questionable.
Effect: The gauntlet is worn on either arm as a bracelet like item and may be worn over or under existing armour. It provides no AP value. When first acquired, the GM is encouraged to roll 2D10 to determine the number of charges it has and keep the number hidden. The locator is a small item and may be placed anywhere and activated as a half action. It emits an almost undetectable signal which can only be devised using specialist auspex. The gauntlet may then be activated as a full action, should the locator be active, the wearer is transported to the precise location of the locator beacon irrespective of where it actually is. This may place the wearer in a difficult situation if it is on a hostile environment. Transporting the user to and from the locator requires one charge per journey as well as recovering the locator however longer journeys may require more at GM discretion. Should the number of charges reach zero then the gauntlet ceases to function and cannot be recharged.
Explanation: A quirky little thing, with this you could cross the entire galaxy almost instantly if you can get the locator there...problem is though that you dont know if you have enough charges to get you back again or where the locator ended up!
And those are some initial ideas...any more though?
