Mariner's Bane

A clear liquid, almost indistinguishable from salt water, this poison was often used to eliminate naval targets of opportunity by less than savory pirates, assassins, and admirals. The chief ingredients are salt water, wood collected from the hold of a wrecked ship- usually one sunk in battle, the bloodier the better, but any suitably tragic accident will suffice-and any one of a number of slightly more Conventional poisons (the inventors swear by distilled Wyvern or Manticore venom for the best results). The poison is added to the salt water and a ritual calling on the vengeance of the sea for the victims of the shipwreck performed, at which point the wood from the wreck is added. The result is a poisonous substance that is almost impossible to determine as a poison, instead taking on the characteristics of fresh seawater.
Although indistinguishable from salt water by any normal inspection, a detect Poison and Disease spell will reveal the true nature of this substance. The target must make a DC 15 WIS saving throw. On a failed save the target becomes obsessed with water (especially the ocean) for 1 hour. The target must use its action to move towards or into the nearest large source of water that it knows of. Once submerged in water, the target must make a DC 13 WIS saving throw on each turn spent submerged and poisoned. On a failed save the target attempts to breath in water and drown itself resulting in 3d10 necrotic (?) damage. On a successful save the target is no longer under the influence of the obsession with water.
