My friend plays as Michael McGlen most of the time

Now one game, he decided to draw an injury card

He drew Concussion, -1 Focus

His base focus is 1, and he gets -1

Does this mean he can never move his skills again until he retires/devoured/remove concussion by encounter?

That is more or less correct, however there are things that can increase his focus again. Camilla's Ruby (unique item) or Corina Jones (Ally, DH expansion) can do it. There is also a Cotdp ally, Sarah Danforth, I think, who gives +1 focus and draw an Exhibit item.

My friend will scream at Cthulhu if he gets Concussed then.

heh heh if you think that's bad listen to this one.

I heard from a friend that in one of his games Luke was forced to come out of his first gate with a very strong monster on it completly ill equipped to fight it. He had Wrack but those who know the spell know that it only works after getting in a fight with the monster so he was still stuck there. He had maximized his sneak (I can hear the veteran's chuckling as they can see where this is going) in hopes of passing a sneak check to get away.

After a few turns of trying and failing he just took the hit and went to the hospital. Oh course he got concussed. Now Luke also has 1 focus but he only has 3 max speed. Since his sneak was currently maxed... lets just say he wasn't going to be doing very much that game.

Pfft, at least he could camp there, looking for the encounter that allows him to remove an Injury .

That's rich coming out of you. Every turn wasted looking for the doctor is a turn the Ancient One have time to wake up. And from what I know, you count yourself as lost if it wakes up.

Well, you do have 3 more investigators to go around, but if playing a 4-player game, the player stuck at the Hospital might be unhappy of course. Of course, taking an Injury/Madness is an option, rarely are you forced to take one.

And final combat is draw or loss .
