I remember in Minechem we could spike foods with stuff like cyanide and (I think) lysine. Could this potentially return?

It could potentially return. I'm not fully decided on if I want to re-implement this feature and if so how I would do it.

Alright, thanks for the prompt response. I was curious.

Sorry if this is semi-dead, but I am currently working on an add-on that will (hopefully) include this! before I sink a ton of time onto it, have you changed your mind on adding it, Dark_arcana?

There's currently no plans to add this as a feature to the current version, so if you're interested in making an addon for it, please go right ahead!
