Staff of Binding

Made from stout oak with steel bands and bits of chain running its entire length, the staff feels oddly heavy. This staff has 10 charges for the following properties. It regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff constricts in upon itself and is destroyed. Spells. While holding the staff, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC: arcane lock (2 charges), hold monster (5 charges), hold person (2 charges), lock armor* (2 charges), or planar binding (5 charges). Spells marked with an asterisk (*) can be found in Deep Magic for 5th Edition. Unbound. While holding the staff, you can use your reaction to expend 1 charge and gain advantage on a saving throw you make to avoid being paralyzed or restrained.
