Maybe I'm being too nice, but I'm going to interpret this favorably and assume that Dorgath was still checking the passageway..."Let's go then." Same plan as before we were ambushed regarding the door.
That last one is right, you can make a cursory check as you walk along, but a full check takes additional time.How much would it slow us down to check the walls/passages as we travel for secret doors? Or can I do a "cursory" check as we walk along, at maybe some minus number, if doing a full check will take too much time?
