I’m against making this apply for all compounds, as at that point we might as well remove the general “storage” concept entirely.
It was brought up before that oxytoxy could use this kind of storage as fundamentally the created toxin ought to be stored in the oxytoxy “vacuoles” before emitting it.
The one problem I see with this design is that it makes storage even less important. Already players mostly ignore the vacuole or other ways to increase their storage. Doing this change would make storage even less important. Does anyone have thoughts about those points?
