Wesarin grants these deadly throwing knives to her favorite assassins and to representatives with vital missions. They function as regular throwing knives, but if the knife deals 0.5 damage or more, it infects the target with -2 Int, -2 Wis, 2d4 damage per round, and 3d4 fatigue per round for 2d4 rounds.
Miasmic Knives are great for assassins. Would your assassin worship Wesarin to get a few? What kinds of enemies would you use them on? Mind Weave Divine Artifacts are very different than enchanted items. They can do a much wider range of things. Any you would like to see? Comment below and let us know!
