The Conjurers Dagger This dagger was originally used in magic shows, but was later adapted for actual combat. It has a number of magical enhancements - it ceases to exist when not needed and hidden about the person and can be drawn from anywhere where it will automatically form in the owners hand. It has uncanny accuracy when thrown, but actually teleports directly into the target instead of crossing the space between them. It can also be transformed into doves, roses, playing cards or a white rabbit.

Your search for "Mix tape" produced the following result:

Doomforall's Personal Mix-tape - Appears to literally be Doomforall's personal mixtape. It seems to contain artists including Florence + The Machine, Alela Diane, Coldplay, Muse and lots of odd bits and bobs from elsewhere. The only unusual thing about it seems to be that during battle it will transform into dramatic classical music with lots of percussion to set the mood.
