If you are wearing the Ebony Mail when you install this, please unequip it and then equip it again.

The Complete Alchemy and Cooking Overhaul mod has a bug where the Ebony Mail's poison cloak effect stops working if the wearer is a vampire/undead or has 100% poison resistance or immunity. I've posted a bug report but until it gets fixed I made a fix for myself and I'm sharing it with everyone who might need it. Flagged as an ESL. Load it after CACO, obviously.
