What's the point of leveling him up without abilities? Plus, the wasps don't stack above the limit; he currently has one, and even if the story phase is skipped, only one will be restored, up to a maximum of two. Remember, they would have been wiped out on the wall back then.
Looks like we need to run and try to attack the Observers. With a double turn, they should perform well as sappers. Otherwise, if we stand still, we'll all be slowed down and end up spending even more time in the red zone.
