Zaikk's Talon is a magical item in Divinity: Original Sin 2
"The Black Ring have long studied the toxins that fester in the desiccated bodies of the Undead. Their charismatic necromancer Zaikk Dtell was the first to discover that by breaking off just one withered finger, a scheming villain can turn a potion of healing into one of poison..."
Zaikk's Talon is a magical tool that is used to turn healing potions into poison potions of the corresponding level, or to turn normal food & drink items into poisoned versions of themselves. This is useful for undead characters since poison heals them. Zaikk's Talon is never consumed, so there is no need to carry more than one. While it counts as a poison source for consumables, it doesn't work when combined with weapons, so you'll need to continue to use other poison sources to enchant weapons with the poison effect.
Where to find:
- Zaikk's Talon can be found in the Hollow Marshes on the isle of Fort Joy.
- Can be purchased from Zaleskar
