I finally took everyone's advice and got an authenticator, then I got game mail that I'd earned a companion. Ho-K, so? Other than getting in the way, what do they do? I know it sounds nuts, but whenever I have a permanent or temporary companion (e.g. the kid from 'take your rugrat to work' week). I play differently - 'protecting" the tag-along and fighting defensively rather than aggressively. Dumb, huh?
Question - can the companion be hurt or attacked, or are they somehow immune?
