Bug Patrol Skirmish, round one - part one (Erin, Matilda, Sanae)
The lightning reflexes of the bug catch all three of the women by surpirse. Although they spot it some distance away, it closes that gap in what seems like the blink of an eye. The creatures flies in low over the brush, one claw lashing out as it streaks nearly straight into Erin before she can even raise her Thunder Staff. Fortunately, the foliage prevents the creature from getting a clean strike and it only bruises the artificer (3 hp damage). Erin manages to aim the Thunder Staff at the monstrous vermin, which responds by bringing its mandibles together with a terrible SNAP on the outstretched arm. Although the jaws bite deeply into her flesh (10 hp damage). , Erin is able to fire the weapon more or less directly into the creature's mouth (I went ahead and rolled the attack - a confirmed critical hit!). She actually sees the creature's carapace bulge slightly as the bubble of force bursts within it and it drops into the bushes, momentarily senseless.
Overhead, all of you can still hear the other insect on the far side of the leafy forest ceiling, sounding like an oversized angry hornet.
Matilda and Sanae, since the creature won the initiative, you can alter/take your actions for this round. If you wish to pinpoint the location of the other bug, you may take a move action and make a Listen check (DC 8) to do so.
