So, I'm playing a cleric of death (sort of a holy hospice worker), and she's one of the most responsible characters in the party, and I always end up being the tin dog and guarding the caravan we've been hired to guard while everyone else goes to find the wizards who've been stalking us or investigate the burning building that another party member just blew up. Any ideas on how I can justify an über responsible character following everyone else off to do interesting things and leaving the caravan to possibly get looted?
