Magic items are considered to be unique – you can only have one of each in your army unless otherwise stated in the magic item's rules. Whilst I describe the magic items in this appendix as 'common' I mean to say that they are common to all armies in the Warhammer world and not that they are commonplace in any sense. Even the least potent magic item is a dangerous device, steeped in the fickle powers of sorcery, and is extremely rare. A fortunate hoarder of trinkets can consider himself lucky to see one example of a particular 'common' magic item in his lifetime, if at all.
