Shadowmeld

Is there any way to have both a shadowmeld that works at night and one that works during the day in a single map? I cant even be sure you can do it during the day, ie changing programming or lighting or some other nonsense. There's no available data of the sort in the ability editor tab so im a bit confused. Anyone know anything?

I'm not sure how you would make a shadowmeld that works during the day, but if you can make one, you can set it so when it's day, a trigger removes the Shadowmeld (Night) and adds the Shadowmeld (Day) ability to the specified unit(s). I remember that in Reign of Chaos, I made a ring (based on the One Ring from LotR) that mae you invisible whenever you weren't moving, day or night. However, I can't seem to remember how I did it, or if you can even do it in TFT. Sorry I can't be of more help right now, but I'll keep looking for some way and let you know if I see one.
