Demonic Leftovers

The Demonic Leftovers, nicknamed this by the original Charmed Ones (Piper, Paige, and Phoebe), were several different weapons left behind by demons and other evil beings who were vanquished by them. The sisters rarely used these weapons, but were not hesitant to reach for them in a time of need.

They have yet to be seen in Destined, and it is unknown if the family still owns these weapons. However, it is possible that if they did still own the trunks that they would have newer weapons and armor.

Charmed
The original Charmed sisters, Paige, Piper, and Phoebe, kept the leftovers in a chest in the attic of the Halliwell Manor. Included in the chest were an axe, presumably from a tracer demon, a mace, and a Darklighter crossbow which was stolen from a Darklighter.

They used these weapons to protect themselves when both their identities and powers were temporarily stolen by the Stillman sisters.
