So I've been trying to play about with the Queen Larva (or Larva Queen, which ever way round it is) and I cant get the consume ability to work. I can go into a critter but when I take control it doesn't have the button to consume. I've gone into Data and added the ability and the button but its not there. Is it maybe an issue with the unit changing hands?
Will I need to do anything to replace the Larva once she consumes or will the ability take care of all that for me?
You can open the Blizzard mission featuring the queen to have a look how Blizzard used it themselves. Since there is no way to add an ability to a unit at runtime, I am pretty sure all available targets would need the consume ability beforehand.
