I sneak off to the shadows, to stab the drow from behind. [Rogue]

You decide to take out the leader first, and shimmy behind the group.

As the arrogant drow is still goading and mocking the others, you try to go as unnoticed as possible, along the steep precipice to the right of the wide path, which you have followed so far below.

If you could just get behind her. A quick dagger to one of her vitals might turn arround this dangerous encounter in one fell swoop. Maybe her spiders won't even fight without their mistress, you ponder, as you duck behind a rock fomation and out of sight, having to tiptoe along the narrow edge of the precipice, and the looming darkness below you.

Roll dexterity.
