can tyrus be attacked by monsters in Blood and Betrayal? if so the OL could win in one foul swoop. the reason i ask is it doesn't say he is a hero unless i missed it. we haven't started yet so this will affect the outcome.

Tyrus can be attached in the first encounter, because the quest rules say to treat Tyrus "as a hero figure...".

However, he's not a hero figure during the second encounter, and thus cannot be attacked.
