Khakkhara (5e Equipment)
From D&D Wiki
A khakkhara, sometimes known as a shakujo, is a specially-constructed ringed staff used as a holy symbol or weapon sometimes used by monks. The staff's rings serve two main purposes: to warn small creatures to move from the wielder's path to avoid being accidentally trodden on, and to alert the faithful that there is a priest nearby.
While you are carrying a khakkhara, you have disadvantage on Dexterity (Stealth) checks.
As a weapon, a khakkhara is treated as a quarterstaff. When you make a melee attack with a khakkhara, you can try to slam the staff's rings into the opponent's face; on hit, the attack deals 1d4 bludgeoning damage instead of the normal damage for a quarterstaff, and the target must succeed on a DC 10 Constitution saving throw or be blinded until the end of its next turn.
