Dagger of Venom
Rare magic weapon (dagger)
Property: You gain a +1 bonus to the attack rolls and the damage rolls you make with this dagger. The saving throw DC of any poison you apply to the dagger increases by 2. Once per day, you can use an action to cause thick, black poison to cover the dagger’s blade. The poison remains for 1 minute or until you hit with an attack using this weapon. When you hit a living creature with this weapon while it’s coated in this poison, the creature must make a DC 15 Constitution saving throw. On a failed save, it becomes paralyzed for 1 minute.
The black, obsidian blade of this weapon is serrated on one edge. Its pommel is carved to resemble two fanged serpents that twine together, their outstretched heads forming the blade’s quillon. Anyone wielding the blade notes a bitter, acrid scent from it. A dagger of venom is most often crafted for the use of a yuan-‐ti or a powerful assassin. Each of these weapons has a distinct pattern to its blade or pommel that indicates its original owner. Assassins’ guilds and yuan-‐ti cults prize these blades as relics. If news of such a dagger reaches them, they send agents to collect the weapon by trickery or force.
