Poisonous Quiver

Attacks using projectiles stored in this quiver are
considered magical. Once per day, as a bonus
action you may speak the Command Word
"poison" and the next projectile pulled from the
quiver will be coated in poison. If the projectile
hits for damage, the creature must succeed on a
Constitution saving throw or take 2d12 poison
damage and is Poisoned until the end of it's next
turn. A creature that succeeds takes half as much
damage and isn't Poisoned.
Requires Minor Attunement.
