I think I would allow solid mirages pretty early if that is the direction you want to take it in.
You would have to channel the Overdrive, but you could do other things while channeling the Overdrive as long as nothing breaks your connection.
There would also be some kind of indication on your character and whoever you are using it on.
Romans 8:31 What, then, shall we say in response to this? If God is for us, who can be against us?
1 Corinthians 13:1-3 If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.
