If Larian wants to force us to run ... there are other (and much better) means to achieve that ...
Personaly i would choose endless spawn ...
Since the event triggers ... every next round another two Cambions would show up ... i gues no party would stick around longer than two turns.

Using that (forcing us to take certain direction) as an argument for restricting us from accesing essential mechanics of our companions, during TUTORIAL seems a little miss. :-/
