Hearing the war cry from behind her, Nydilind will turn to see the attackers. Deciding that people running towards her with weapons drawn, yelling, while she is trapped don't likely mean to give her a hug, she prepares to defend herself.

OOC:
I'm not sure if she would have initiative, so what she will do depends on that. If she goes before the attackers, she will take a shot with her bow before they approach. If she can't get off a clear shot for any reason, or if they approach before she can take a shot, she'll go with two weapon attacks using the short sword and dagger.

If she can get the shot off with the bow, she also has the point blank feat, so if they are within 30 feet, she's got an additional +1 to hit, for a total of +6.
