just wondering what happens to yubots if the user is IM-2 from weapons such as riotstoppers. are they still able to move and act?
You can still spend Orders on the controller+servant, but obviously the controller won't be able to perform most Skills. Note that the Yudbot doesn't have the Engineer or Doctor Special Skill, and it's the controller actually performing those Skills, so this won't be possible: Q: Can I use G: Servant to cancel Immobilized state from his linked Engineer? A: No. As the G: Servant trooper doesn’t have the Engineer Skill it is the G: Servant’s Controller who is performing the Engineer Skill, and this cannot be done while in Immobilized state.
