Voadam
Legend
We found one in an old Warhammer game (1st edition). The one player to draw from it got the experience one, something like 10,000 xp. The GM did not convert to the different scale of WFRP xp. In WFRP each 100 xp advances something and you earn about that much a night. So this petty thief became a master thief master alchemist, master priest of the thief god instantly basically going from a 4th to 5th level NPC equivalent character to an epic spellcasting one. While everyone else remained as they were.
