Brandon went about his search so badly that he got rewarded with a<div class="spoiler_container"><div class="spoiler_header" onclick="hideSecond (this);" role="button">burst of acid</div><div class="spoiler_body">dex DC 12 vs 7(3) acid damage</div></div>in his face.  At least no one else was close enough to get hurt by it, even if a few drops came within inches of the goblins feet.<br/><br/>The bat finds its way back to its nest and wont be any trouble for a while.<br/><br/>As for the chest itself, it appears undamaged from the acid burst and there's no indication whether the trap was a one time thing or if it resets itself afterwards.
