note....there are MANY "a wary guard" ...but the one that is Capitalized (A Wary Guard)(should be a Kobold) is the trigger mob for Sirana, the Knife Mistress.
Say, "understand" to "A Wary Guard" and she will spawn.
As a dr00d, I pac'd the 2 mobs surrounding it, then waited for the pather gnome to pass, then did trigger then pulled to the corner right by where it spawned. Fun fight. Have your group heals ready!
