So my friend plays Greyjoy, Raiders and boats he calls it.
He has Naval Escort. It's really powerful and the way that he uses it seems really broken but at the same time I don't think he's using it incorrectly.
Basically he kneels 2-3 warships to give 2-3 of his guys 2-3 strength but he still has a few warship locations remaining. When/If he's about to lose a challenge he will then kneel his other warship locations to give his guys another 1-2 strength boost and then usually wins the challenge by giving one of his guys +4 or +5 strength.
A strict reading of the card sounds like he can do that.
So my question is, can he really do that or does kneeling more warships overwrite the previous use of Naval Escorts ability?
