Bat
Bats live in Bat Cave: its 8 areas have them from level 60 up to level 330.
Their experience and gold are 1.35 times a Slime’s of the same level and colour. Any Bat can drop Bat Wing, a material only Bats give. A Metal Bat’s HP doesn’t grow the way the others’ does: it’s just 4 times its level, and almost nothing gets past its defence (see Metal monsters). Metal Bats only appear in dungeons, never in areas: see Waves and time.
