IRE Asks: What unique artefact would you own?  Dwarf Priest
Lamp of Mookie:   Every time you rub it, a female 18 year old
novice is created, ready and willing to "learn."  Seconding lamp
of mookie    My own aethership!  Is something I wouldn't mind
having.  Mulligan. Redeemable for one do-over. Resets.  Senses
ripped soul and transports you immediately into a safe location.
Pendant of Psychometry. Sense the history of any item. Where it
came from, who held it last, past owners...  The Lucretian
Index. The book of books.  A ring that allows a Shaman to Curse
right through cursewards.    Mandala of Circadian Might. Alter
the time of day in your room, area, continent, or plane.  Some
kind of lobster-gun, or something. Aim it at someone to turn
points of their physiology into a crustacean carapace. Hitting
their legs would weaken them obviously but if you hit their arms
by mistake, those claws could be trouble.  Giant fireworks.
Like, giant.  A portrait of profound perfection, to take damage
in my place.
