The alchemy specific magical poison, which requires a tear to make, and which NOBODY uses since achilles has a 22% dehaste vs the poisons 20%. Add to that the fact that a sin already has to juggle multiple weapons to apply a full compliment of debuffs, so there's zero reason to even add this expensive debuff poison into the mix.
For this item to have a purpose the delve should be at least 30%, which is available on MANY styles in the game already. my 2c
