An ROUS is probably not an issue.
And, again, even 1st-level adventurers are trained with a basic proficiency in whatever weapon they wield - sword or spell. They are not utter noobs, not commoners, and should not be threatened by vermin. The game is Dungeons & Dragons, not Cornfields and Cottontails.
