Staff of the Adder (2014 Dungeon Masters Guide)

uncommon · Wondrous Item · Requires Attunement by a cleric, druid, or warlock

You can use a bonus action to speak this staff's command word and make the head of the staff become that of an animate poisonous snake for 1 minute. By using another bonus action to speak the command word again, you return the staff to its normal inanimate form.

You can make a melee attack using the snake head, which has a reach of 5 feet. Your proficiency bonus applies to the attack roll. On a hit, the target takes 1d6 piercing damage and must succeed on a DC 15 Constitution saving throw or take 3d6 poison damage.

The snake head can be attacked while it is animate. It has an Armor Class of 15 and 20 hit points. If the head drops to 0 hit points, the staff is destroyed. As long as it's not destroyed, the staff regains all lost hit points when it reverts to its inanimate form.

Versatile

This weapon can be used with one or two hands. A damage value in parentheses appears with the property—the damage when the weapon is used with two hands to make a melee attack.
