Spell Cast Dependant Status?

There may be two ways to go about making the status effect incurable. The first (and easiest) way would be just to hijack a current status effect slot. This would likely entail re-writing the effect entirely to match what you want, and then just don't allow any items or spells to cure it.

This is kind of what I expected to Hear in response to my Question, but I'm not sure that I can make it Fit my Vision, ya know? But I suppose even Visions can be Revised... But it does open up New Possibilities.

As far as transferring it (which is the gist I'm getting from your poison example)

Yeah, okay. In Retrospect, that was totally a Stupid Example, and would obviously cause confusion. I apologize.

Okay. So this is what I want, Actually.

Terra is Stricken with CountDown at the Beginning of Every Battle. Only a Successful Cast (ie, a Hit) of Drain will Cure it. Or Resetting the Count would actually be Perfect.

That would make it Necessary to, On Some Occasions, cast it on an Ally. Which, yes, makes for a fun Plot Thread.
