                  Vicious Night Shadow Bat

                  This mob does not report x,y coordinates (loc). If this is true, this mob cannot be located using World Search.

                  A Word About Common Drops: Every mob in the game has a chance to drop Sigils, Health Potions, Mana Potions, Ammunition, Runes and Festival Items, as well as a few rarer items such as Amulet of Light Amulet of Light. For this reason, we discourage listing them in the Known Drops section. See Common Drop Table for more information. Exception: All mobs always drop the same Production Rune and we will list it. Also see Bloody Gallery (Zone Loot Table) for more information about common drops in this zone.
