Yeah, post when you want and work off each other in battle. Make sure you don't control the other people though and try to have your character react in the way they should react, even if it means them getting hit and possibly hurt. It is the danger room after all. Remember, they have a team mate with healing ability and the teachers won't let them get killed in training.<br/><br/>As for whether their powers will work, I'm sure that even the characters themselves don't know, but that is sort of the point here. To push them to their limit or past it to really see what they are capable of. To really encourage them to let loose with their powers and to explore with their abilities. Be creative with them and really explore the possibilities.
