Darkstaff (5e Equipment)

Staff, rare (requires attunement by a spellcaster)

This staff was crafted centuries ago, weaving together the wispy strands of shadow itself into a twisted black staff. You can use an action to speak this staff's command word and throw the staff on the ground within 10 feet of you. The staff becomes a shadow under your control and acts on its own initiative count. By using a bonus action to speak the command word again, you return the staff to its normal form in a space formerly occupied by the shadow.
On your turn, you can mentally command the shadow as a bonus action if it is within 60 feet of you and you aren't incapacitated. You decide what action the shadow takes and where it moves during its next turn, or you can issue it a general command, such as to attack your enemies or guard a location.
If the shadow is reduced to 0 hit points, it dies and reverts to its staff form. The staff then shatters and is destroyed. If the shadow reverts to staff form before losing all its hit points, it regains all of them.
Spells. This staff has 20 charges. While holding this 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 and spell attack bonus: black tentacles (3 charges), darkness (6 charges), eldritch blast (11th level version, 5 charges), etherealness (1 charge), raise dead (5 charges), remove curse (3 charges).
